1
00:00:00,000 --> 00:00:03,480
Hey everyone, welcome y'all.

2
00:00:03,480 --> 00:00:08,000
So from today, I'm going to start a new series on manual software testing on YouTube live

3
00:00:08,000 --> 00:00:13,960
sessions and especially beginners, they have requested to upload a new series on manual

4
00:00:13,960 --> 00:00:19,960
software testing, especially manual testing concepts and manual testing process and Jira

5
00:00:19,960 --> 00:00:23,520
and as well as agile process along with some project.

6
00:00:23,520 --> 00:00:25,520
So I'm just plan for that.

7
00:00:25,520 --> 00:00:27,780
And from today, we are going to see.

8
00:00:27,780 --> 00:00:32,020
So especially for today, we are going to start some basic concept from manual testing.

9
00:00:32,020 --> 00:00:36,180
Okay, now let's get start.

10
00:00:36,180 --> 00:00:41,420
So manual testing, we are going to learn in three different phases, or we can say modules.

11
00:00:41,420 --> 00:00:48,140
The first module, the first module testing concepts, your first module, we are going

12
00:00:48,140 --> 00:00:50,180
to learn testing concepts.

13
00:00:50,180 --> 00:00:51,620
So what is testing concept mean?

14
00:00:51,620 --> 00:00:56,300
Basically, this is all completely theoretical concept is okay, but I don't want to get you

15
00:00:56,300 --> 00:00:57,300
bored.

16
00:00:57,300 --> 00:01:01,860
So I'll interact more and I'll give practical experiences and some scenarios also, don't

17
00:01:01,860 --> 00:01:02,860
worry.

18
00:01:02,860 --> 00:01:04,940
So testing concept, this is module one.

19
00:01:04,940 --> 00:01:09,540
In this particular module, we are going to learn some very basics of testing, like what

20
00:01:09,540 --> 00:01:10,900
is software testing?

21
00:01:10,900 --> 00:01:12,660
What are the different levels of testing?

22
00:01:12,660 --> 00:01:16,300
What are the different types of testing we have to conduct on your application?

23
00:01:16,300 --> 00:01:17,380
Like what is software?

24
00:01:17,380 --> 00:01:19,780
What are the different types of software are available?

25
00:01:19,780 --> 00:01:23,180
And SDLC, SDLC, like a lot of things are there.

26
00:01:23,180 --> 00:01:27,620
So we are going to learn some basic concept from testing, because before going to conduct

27
00:01:27,620 --> 00:01:31,900
testing, we have to know what kind of testings are there and how we have to conduct those

28
00:01:31,900 --> 00:01:33,100
testings.

29
00:01:33,100 --> 00:01:34,620
So that is a theoretical part.

30
00:01:34,620 --> 00:01:36,700
Okay, so testing concept.

31
00:01:36,700 --> 00:01:39,900
And if I just look at the curriculum, so the basic concept will be there, like what is

32
00:01:39,900 --> 00:01:46,780
software testing, types of softwares, and software quality, what is project and product,

33
00:01:47,540 --> 00:01:53,820
testing, and SDLC, SDLC, a lot of things are there, and test design techniques.

34
00:01:53,820 --> 00:01:56,940
These are very, very important topics which we are going to discuss.

35
00:01:56,940 --> 00:01:59,900
And white box testing, black box testing, what is there?

36
00:01:59,900 --> 00:02:01,580
And functional and non-functional testing.

37
00:02:01,580 --> 00:02:04,540
So all these things we are going to discuss as part of module one.

38
00:02:04,540 --> 00:02:07,580
So this is mostly theoretical part, okay?

39
00:02:07,580 --> 00:02:11,620
Because before jumping into the practical part, we have to know some basic concepts

40
00:02:11,620 --> 00:02:13,140
theoretically.

41
00:02:13,180 --> 00:02:17,860
So almost four to five sessions we are going to spend on this particular module, software

42
00:02:17,860 --> 00:02:19,420
testing concepts.

43
00:02:19,420 --> 00:02:23,260
So this is the first module, theoretical part, okay?

44
00:02:23,260 --> 00:02:29,100
Then basically this module says like what, like what to test, okay?

45
00:02:29,100 --> 00:02:33,660
And the second module is a practical part, okay?

46
00:02:33,660 --> 00:02:37,860
Second module is a practical part, software testing project.

47
00:02:37,860 --> 00:02:43,660
So here we are going to start a project along with some concepts, like how to write, how

48
00:02:43,660 --> 00:02:48,220
to analyze the requirements, how to write the test plan, how to write the test cases,

49
00:02:48,220 --> 00:02:53,980
how to execute our test cases, and we are going to learn about bugs, bug or defect lifecycle,

50
00:02:53,980 --> 00:02:55,580
how to report the bugs.

51
00:02:55,580 --> 00:02:58,280
So these concepts are purely practical part.

52
00:02:58,280 --> 00:03:06,460
So in this module, we are going to learn project, and this is purely practical orientation.

53
00:03:06,500 --> 00:03:09,660
And here we are going to learn how to test, okay?

54
00:03:09,660 --> 00:03:14,540
In the first module, we are mainly focusing on what to test, because the theoretical part.

55
00:03:14,540 --> 00:03:18,420
In the second module, we are going to test, like we are going to test the application

56
00:03:18,420 --> 00:03:20,900
directly, like how to test.

57
00:03:20,900 --> 00:03:23,300
So what are the different techniques are available, right?

58
00:03:23,300 --> 00:03:26,860
How to write the test cases, how to review the test cases.

59
00:03:26,860 --> 00:03:30,660
So these things will be part of module number two, testing project.

60
00:03:30,660 --> 00:03:36,300
I'm going to introduce one e-commerce application, and I'll also show you the FRS document and

61
00:03:36,300 --> 00:03:40,860
the requirement document, how we'll get the requirement from the customers, and then how

62
00:03:40,860 --> 00:03:45,420
to write the test cases, how to review them, how to execute bug life cycles.

63
00:03:45,420 --> 00:03:47,700
Everything will be part of this model testing project.

64
00:03:47,700 --> 00:03:51,760
So here you will get the practical experience, okay?

65
00:03:51,760 --> 00:03:55,900
So this is a model number two, because we cannot directly jump into project because

66
00:03:55,900 --> 00:03:57,940
before that, we need to know some basic concepts.

67
00:03:57,940 --> 00:04:01,460
If you know the what part, then we can jump into how part.

68
00:04:01,460 --> 00:04:03,220
So what to test and how to test.

69
00:04:03,220 --> 00:04:06,680
So second module mainly focus on how to test.

70
00:04:06,680 --> 00:04:13,420
And once these two modules are completed, then the module three is for agile process.

71
00:04:13,420 --> 00:04:17,980
This is purely process oriented, because in the nowadays, all the companies are using

72
00:04:17,980 --> 00:04:20,520
agile process, okay?

73
00:04:20,520 --> 00:04:24,660
And you have to know this process until unless you know this process, it is very difficult

74
00:04:24,660 --> 00:04:26,900
to survive in the company.

75
00:04:26,900 --> 00:04:31,460
So previously waterfall model, spiral model, there are traditional models are available

76
00:04:31,700 --> 00:04:35,140
because these are process model, because if there is any company, there should be some

77
00:04:35,140 --> 00:04:37,360
process followed by people, right?

78
00:04:37,360 --> 00:04:42,860
So here agile process, which is very, very important, and most of the companies are following

79
00:04:42,860 --> 00:04:44,280
agile process.

80
00:04:44,280 --> 00:04:49,900
So here in module three, we are going to discuss agile process, like how we will get the requirements,

81
00:04:49,900 --> 00:04:54,980
how to write the stories and epics, how we can do the backlog plan or sprint plan, how

82
00:04:54,980 --> 00:04:56,280
the cycles will go on.

83
00:04:56,320 --> 00:05:01,500
So how we can interact in the project, interact within the project team, scrum, all these

84
00:05:01,500 --> 00:05:04,440
things we are going to discuss as part of agile process.

85
00:05:04,440 --> 00:05:09,720
And here itself, I'm going to discuss about one important tool called Jira.

86
00:05:09,720 --> 00:05:15,760
So Jira is basically agile test management tool, or we can say agile tool.

87
00:05:15,760 --> 00:05:20,360
And in this particular application, we can track everything in the software development

88
00:05:20,360 --> 00:05:25,600
from the beginning from the requirement to till we deliver the software to the customer,

89
00:05:25,600 --> 00:05:29,720
everything we can track into this particular tool, even testers and developer, each and

90
00:05:29,720 --> 00:05:35,560
every activity, like test cases, test plans, execution status, reports, everything we can

91
00:05:35,560 --> 00:05:37,980
manage in this tool, okay?

92
00:05:37,980 --> 00:05:41,600
And previously, before these tools are available in the market, people are using like Excel

93
00:05:41,600 --> 00:05:46,680
sheets and Word documents, instead of that, we can track everything in the tools, okay?

94
00:05:46,680 --> 00:05:51,320
So this is agile process, we are going to discuss, which is Jira tool, there are a lot

95
00:05:51,320 --> 00:05:55,560
of concepts are there guys, so I'm not writing in detail because I already have the curriculum

96
00:05:55,560 --> 00:05:56,560
here.

97
00:05:56,560 --> 00:06:00,480
So I share this curriculum later, you guys can go through the topics, okay?

98
00:06:00,480 --> 00:06:06,080
So these are the three different modules which we are going to cover as part of manual testing.

99
00:06:06,080 --> 00:06:10,160
So with this Jira tool, we will able to complete manual testing, okay?

100
00:06:10,160 --> 00:06:16,920
And apart from that, in addition, I'm also going to share you the SQL videos, because

101
00:06:16,920 --> 00:06:22,160
SQL is not part of our code, because SQL itself will take 10 to 15 sessions.

102
00:06:22,160 --> 00:06:27,320
So I'm going to provide the video sessions or recorded video sessions, apart from this

103
00:06:27,320 --> 00:06:32,200
manual testing course, okay, you guys can go through the SQL videos, and that is also

104
00:06:32,200 --> 00:06:34,840
very important for testing prospectivity, okay?

105
00:06:34,840 --> 00:06:39,200
So if you go for an interview, people will ask you some questions from SQL also, along

106
00:06:39,200 --> 00:06:40,800
with the manual testing.

107
00:06:40,800 --> 00:06:43,440
So that is also very, very important, right?

108
00:06:43,440 --> 00:06:47,880
So that will be going to share after completion of manual testing, right?

109
00:06:47,880 --> 00:06:50,960
So this is a part of manual testing curriculum.

110
00:06:50,960 --> 00:06:55,080
And once you completed manual testing, then I'll share automation testing and everything,

111
00:06:55,080 --> 00:06:56,080
okay?

112
00:06:56,080 --> 00:06:58,980
That is a different curriculum we are going to learn, all right?

113
00:06:58,980 --> 00:07:02,320
So for today's session, I'm going to start with the module one.

114
00:07:02,320 --> 00:07:05,720
So are you guys clear so far, everyone, about this curriculum?

115
00:07:05,720 --> 00:07:08,080
Can you please come from in the chat window?

116
00:07:08,080 --> 00:07:12,880
So if you ask any questions, guys, so please interact in the chat window immediately.

117
00:07:12,880 --> 00:07:15,720
And every time I'll ask the confirmation from you guys.

118
00:07:15,720 --> 00:07:20,880
So please put in the chat window, okay, all right.

119
00:07:20,880 --> 00:07:25,080
So let us start with a few, some basic concepts from manual testing, okay?

120
00:07:25,080 --> 00:07:26,800
So today's introduction session.

121
00:07:26,800 --> 00:07:31,940
So I'm just going to cover some basics, basics, like what is software, what is software testing,

122
00:07:31,940 --> 00:07:34,920
and why do we need to software testing, all these things, okay?

123
00:07:34,920 --> 00:07:39,800
So first, let us start with what is software and what are the different types of software?

124
00:07:39,800 --> 00:07:44,600
So people who are completely beginners, okay, and they don't have any ID background, I'm

125
00:07:44,680 --> 00:07:48,520
going to start from very, very basic, guys, from the scratch.

126
00:07:48,520 --> 00:07:50,080
And you don't need to worry about anything.

127
00:07:50,080 --> 00:07:54,400
If you just know how to use MS Word document, Excel sheet, that is that knowledge is enough

128
00:07:54,400 --> 00:07:59,040
and basic internet knowledge is enough to start learning this concept, okay?

129
00:07:59,040 --> 00:08:01,600
So you don't need to worry and afraid of anything.

130
00:08:01,600 --> 00:08:03,280
I'll go from very basic.

131
00:08:03,280 --> 00:08:08,320
If you have not understood anything, please use chat window to post your questions, okay?

132
00:08:08,320 --> 00:08:11,700
All right, so this is a small presentation I have.

133
00:08:11,700 --> 00:08:13,400
So later I'll share this presentation.

134
00:08:13,960 --> 00:08:16,520
Okay, first, let us see the concepts.

135
00:08:16,520 --> 00:08:20,680
And one more thing is for every concept, guys, after explanation at the end of the session,

136
00:08:20,680 --> 00:08:25,320
I will also share the presentation as well as notes and materials, and don't worry.

137
00:08:25,320 --> 00:08:27,960
So you guys can go to them, all right?

138
00:08:27,960 --> 00:08:32,580
So first, let us start with what is software, like what is the types of software?

139
00:08:32,580 --> 00:08:35,920
So everywhere we hear, we heard this term software.

140
00:08:35,920 --> 00:08:41,920
What is software, software, simple definition, everyone know about software, but if you come,

141
00:08:41,920 --> 00:08:45,840
if I ask the definition, most of the people cannot answer this question.

142
00:08:45,840 --> 00:08:48,240
Software, everybody knows the software, we are daily,

143
00:08:48,240 --> 00:08:50,880
entirely every day we are using software,

144
00:08:50,880 --> 00:08:53,920
mobiles or computers, everywhere we are using software.

145
00:08:53,920 --> 00:08:56,080
But what exactly software means?

146
00:08:56,080 --> 00:08:58,800
So if you say definition of the software,

147
00:08:58,800 --> 00:09:03,580
the software is a collection of computer programs,

148
00:09:03,580 --> 00:09:07,760
a collection of computer programs that helps us to perform a task.

149
00:09:07,760 --> 00:09:10,880
Suppose if you want to perform some task, guys,

150
00:09:10,880 --> 00:09:14,560
suppose if you want to do some manual task, right?

151
00:09:14,560 --> 00:09:17,000
So through the mission, I want to do the task.

152
00:09:17,000 --> 00:09:20,200
So that mission needs some software, okay?

153
00:09:20,200 --> 00:09:23,240
So for example, if I take a mobile app, mobiles, right?

154
00:09:23,240 --> 00:09:24,720
So if you have only mobile, right?

155
00:09:24,720 --> 00:09:26,160
We cannot do anything with mobile.

156
00:09:26,160 --> 00:09:29,560
In that mobile, there should be some apps or some software should run.

157
00:09:29,560 --> 00:09:32,560
And with that software, we are doing all the things, right?

158
00:09:32,560 --> 00:09:34,480
Suppose if I take some WhatsApp or LinkedIn,

159
00:09:34,480 --> 00:09:36,480
whatever apps you have in the mobile,

160
00:09:36,480 --> 00:09:39,280
if I don't have those apps, can you use your mobile?

161
00:09:39,280 --> 00:09:40,200
No, right?

162
00:09:40,200 --> 00:09:42,800
So you need to have some software in that.

163
00:09:42,800 --> 00:09:45,320
And then only we can use a mobile.

164
00:09:45,320 --> 00:09:48,160
Similarly, software is a collection of computer program.

165
00:09:48,160 --> 00:09:51,640
How the software will be developed,

166
00:09:51,640 --> 00:09:54,040
which is basically a collection of programs.

167
00:09:54,040 --> 00:09:57,000
And the developers will write a number of programs

168
00:09:57,000 --> 00:09:59,680
and collectively we can call it as a software.

169
00:09:59,680 --> 00:10:01,160
So what is a program?

170
00:10:01,160 --> 00:10:03,600
Program is something called as a coding,

171
00:10:03,600 --> 00:10:06,400
like they will write some instructions to the computer.

172
00:10:06,400 --> 00:10:10,000
So the instructions can be understandable by the computer.

173
00:10:10,000 --> 00:10:13,040
And collectively we can call it as a software.

174
00:10:13,040 --> 00:10:16,080
Software is a collection of computer programs

175
00:10:16,080 --> 00:10:17,840
that help us to perform a task.

176
00:10:17,840 --> 00:10:21,400
If you want to perform some task, we can use a software.

177
00:10:21,400 --> 00:10:23,120
Okay, simple definition.

178
00:10:23,120 --> 00:10:24,360
But in the market,

179
00:10:24,360 --> 00:10:27,120
there are different type of softwares are available.

180
00:10:27,120 --> 00:10:29,600
There are different types of softwares are available.

181
00:10:29,600 --> 00:10:32,480
So mainly there are three categories.

182
00:10:32,480 --> 00:10:35,040
One is system software.

183
00:10:35,040 --> 00:10:37,040
Okay, let me just write some notes here.

184
00:10:37,960 --> 00:10:39,440
Okay, so types of softwares.

185
00:10:39,440 --> 00:10:43,400
System software, and programming software,

186
00:10:43,400 --> 00:10:44,800
and application software.

187
00:10:44,800 --> 00:10:46,880
So these are the three different

188
00:10:46,880 --> 00:10:48,500
types of softwares are available.

189
00:10:49,380 --> 00:10:51,520
Three different types of softwares are available.

190
00:10:51,520 --> 00:10:53,840
One is system software.

191
00:10:53,840 --> 00:10:55,880
I'll tell you what is system software.

192
00:10:55,880 --> 00:10:58,200
Second one is the programming software.

193
00:10:58,200 --> 00:11:00,600
And third one is the application software.

194
00:11:00,600 --> 00:11:02,640
System software, programming software,

195
00:11:02,640 --> 00:11:04,920
then application software.

196
00:11:04,920 --> 00:11:07,240
So what is system software means?

197
00:11:07,240 --> 00:11:09,840
Normally device drivers, operating systems,

198
00:11:09,840 --> 00:11:11,940
servers, utilities, these are all

199
00:11:11,940 --> 00:11:14,680
comes under system software.

200
00:11:14,680 --> 00:11:16,000
What does it mean?

201
00:11:16,000 --> 00:11:19,800
Suppose you have your desktop or laptop, okay?

202
00:11:19,800 --> 00:11:22,960
And you are connecting all the accessories to your computer.

203
00:11:22,960 --> 00:11:26,120
You are connecting keyboard, you are connecting mouse, right?

204
00:11:26,120 --> 00:11:28,200
You are connecting some other screens,

205
00:11:28,200 --> 00:11:31,460
or you're connecting printer to your computer, right?

206
00:11:31,460 --> 00:11:34,000
So these are different accessories or devices

207
00:11:34,000 --> 00:11:36,300
are connecting to your computer.

208
00:11:36,300 --> 00:11:39,060
But if you want to use those devices,

209
00:11:39,060 --> 00:11:42,300
we need to install some additional drivers.

210
00:11:42,300 --> 00:11:44,580
Or sometimes your computer also will come

211
00:11:44,580 --> 00:11:46,260
along with the drivers.

212
00:11:46,260 --> 00:11:49,660
And those drivers also comes under the system software.

213
00:11:49,660 --> 00:11:54,240
And basically these softwares are used to run the systems.

214
00:11:54,240 --> 00:11:56,460
Okay, suppose if you connect,

215
00:11:56,460 --> 00:11:59,720
suppose if you have connected your keyboard to the computer,

216
00:11:59,720 --> 00:12:02,800
how your computer will able to identify your keyboard,

217
00:12:02,800 --> 00:12:04,380
the instructions are coming from keyboard.

218
00:12:04,380 --> 00:12:06,040
It doesn't know basically, right?

219
00:12:06,040 --> 00:12:08,120
So there should be some software.

220
00:12:08,120 --> 00:12:09,840
The computer should have some intelligence

221
00:12:09,840 --> 00:12:12,280
to identify your keyboard, to identify your mouse,

222
00:12:12,280 --> 00:12:14,640
you identify your monitor and everything.

223
00:12:14,640 --> 00:12:17,920
So that is basically comes under the system software.

224
00:12:17,920 --> 00:12:21,000
So device drivers and operating system.

225
00:12:21,000 --> 00:12:23,480
Operating system is what Windows, Linux, Mac.

226
00:12:23,480 --> 00:12:25,560
So these are all operating systems.

227
00:12:25,560 --> 00:12:26,760
So you have a computer,

228
00:12:26,760 --> 00:12:29,080
but if you don't have any operating systems,

229
00:12:29,080 --> 00:12:31,840
how can we use or how can you install other softwares

230
00:12:31,840 --> 00:12:33,840
without using operating system?

231
00:12:33,840 --> 00:12:37,080
Because first, as soon as you start your computer,

232
00:12:37,080 --> 00:12:39,080
operating system must be there.

233
00:12:39,080 --> 00:12:41,000
So on top of operating system,

234
00:12:41,000 --> 00:12:44,080
we are going to install other softwares, right?

235
00:12:44,080 --> 00:12:45,300
That is the base.

236
00:12:45,300 --> 00:12:46,280
Once you have computer,

237
00:12:46,280 --> 00:12:47,840
you need to install some operating system.

238
00:12:47,840 --> 00:12:49,340
It can be anything.

239
00:12:49,340 --> 00:12:51,520
So that is also comes under the system software,

240
00:12:51,520 --> 00:12:55,080
because if you want to run or start system,

241
00:12:55,080 --> 00:12:56,880
we need some operating system.

242
00:12:56,880 --> 00:12:59,840
So there's a reason which is comes under system software

243
00:12:59,840 --> 00:13:03,480
and server some utilities files or some utilities means,

244
00:13:03,480 --> 00:13:05,800
suppose if you write something, right?

245
00:13:05,800 --> 00:13:08,400
If you write some text or if I write some document,

246
00:13:08,400 --> 00:13:13,240
internally, the computer software is able to recognize it.

247
00:13:13,240 --> 00:13:15,120
So to run special software,

248
00:13:15,120 --> 00:13:17,400
we need to also have some utilities.

249
00:13:17,400 --> 00:13:19,560
So these are all comes under system software,

250
00:13:19,560 --> 00:13:23,120
device drivers, operating systems, servers, utilities,

251
00:13:23,120 --> 00:13:24,880
all these things are comes under system.

252
00:13:24,880 --> 00:13:26,800
So basically the system software

253
00:13:26,800 --> 00:13:31,040
will be used to run the systems, okay?

254
00:13:31,040 --> 00:13:33,040
That is a one category of softwares.

255
00:13:33,080 --> 00:13:35,800
And the second category is a programming software.

256
00:13:35,800 --> 00:13:38,000
So what is programming software means?

257
00:13:38,000 --> 00:13:41,000
Compilers, debuggers, interpreters.

258
00:13:41,000 --> 00:13:44,100
So these are all examples of programming software.

259
00:13:44,100 --> 00:13:47,360
That means, suppose developers are writing the code

260
00:13:47,360 --> 00:13:50,820
or some program, how program will be executed?

261
00:13:50,820 --> 00:13:53,820
How the program will be produced some output?

262
00:13:53,820 --> 00:13:55,520
Suppose when I use a computer,

263
00:13:55,520 --> 00:13:57,360
we are giving some input to the computer,

264
00:13:57,360 --> 00:13:59,320
we are getting some output.

265
00:13:59,320 --> 00:14:01,720
So who is processing internally?

266
00:14:01,720 --> 00:14:03,400
When I give some input to the computer,

267
00:14:03,400 --> 00:14:05,800
someone should be there to process that input

268
00:14:05,800 --> 00:14:07,480
and produce the output.

269
00:14:07,480 --> 00:14:08,880
And that thing will be done

270
00:14:08,880 --> 00:14:11,840
by the compilers, debuggers, interpreters.

271
00:14:11,840 --> 00:14:16,040
So these are the softwares which will do some processes

272
00:14:16,040 --> 00:14:18,080
when you run your program.

273
00:14:18,080 --> 00:14:21,200
Normally developers work with these programming software.

274
00:14:21,200 --> 00:14:23,440
So whatever the programs they have run

275
00:14:23,440 --> 00:14:26,240
to execute the programs and providing the output,

276
00:14:26,240 --> 00:14:28,480
the compilers, debuggers, interpreters

277
00:14:28,480 --> 00:14:29,800
will be used internally.

278
00:14:29,800 --> 00:14:32,080
So that comes under the programming software.

279
00:14:33,000 --> 00:14:35,280
And the last one is application software.

280
00:14:35,280 --> 00:14:37,680
So this is a very, very important area

281
00:14:37,680 --> 00:14:39,720
where we have to focus on.

282
00:14:39,720 --> 00:14:40,840
Application software.

283
00:14:40,840 --> 00:14:42,320
So application software is nothing

284
00:14:42,320 --> 00:14:44,880
but the users will use that applications

285
00:14:44,880 --> 00:14:46,940
or users will use that software.

286
00:14:46,940 --> 00:14:49,680
For example, web applications.

287
00:14:49,680 --> 00:14:52,280
So every day we are using web applications

288
00:14:52,280 --> 00:14:56,400
in case of Facebook or LinkedIn or Amazon or online portals.

289
00:14:56,400 --> 00:14:59,140
Everything comes under web applications.

290
00:14:59,140 --> 00:15:00,540
And mobile apps.

291
00:15:00,540 --> 00:15:02,060
Suppose you are using mobile

292
00:15:02,060 --> 00:15:04,260
and you have N number of apps in your mobile.

293
00:15:04,260 --> 00:15:07,740
All those things are comes under application software.

294
00:15:07,740 --> 00:15:09,140
And desktop applications.

295
00:15:09,140 --> 00:15:10,860
So desktop application means what?

296
00:15:11,700 --> 00:15:13,220
You can install those applications

297
00:15:13,220 --> 00:15:15,300
in your laptop or your computer

298
00:15:15,300 --> 00:15:19,060
like MS Word document, Excel, Outlook, Notepad, calculator.

299
00:15:19,060 --> 00:15:22,260
So these are all comes under desktop applications.

300
00:15:22,260 --> 00:15:25,100
So basically there are three kinds of applications,

301
00:15:25,100 --> 00:15:26,780
application softwares.

302
00:15:26,780 --> 00:15:28,780
One is web applications,

303
00:15:28,780 --> 00:15:31,820
mobile applications, desktop applications.

304
00:15:31,820 --> 00:15:33,420
These are the three categories.

305
00:15:33,420 --> 00:15:34,420
So web applications,

306
00:15:34,420 --> 00:15:35,780
if you want to work web applications,

307
00:15:35,780 --> 00:15:37,700
we need to have an internet, okay?

308
00:15:37,700 --> 00:15:40,780
Because through internet we can access those applications.

309
00:15:40,780 --> 00:15:42,860
And actual applications will be installed

310
00:15:42,860 --> 00:15:45,460
somewhere in the remote servers.

311
00:15:45,460 --> 00:15:46,300
And mobile apps.

312
00:15:46,300 --> 00:15:48,140
So everybody will know about this.

313
00:15:48,140 --> 00:15:49,440
So from the Play Store,

314
00:15:49,440 --> 00:15:52,100
we can download and install mobile apps and we can use it.

315
00:15:52,100 --> 00:15:54,540
They are all comes under application software.

316
00:15:54,540 --> 00:15:56,260
And desktop applications means

317
00:15:56,260 --> 00:15:59,580
the application which we can install on your local machine.

318
00:15:59,580 --> 00:16:00,580
Even without internet,

319
00:16:00,580 --> 00:16:03,180
also we can use desktop applications.

320
00:16:03,180 --> 00:16:05,780
So like I'm using Notepad to typing something.

321
00:16:05,780 --> 00:16:07,700
This is a desktop application.

322
00:16:07,700 --> 00:16:09,700
So calculator is a desktop application.

323
00:16:09,700 --> 00:16:12,420
Your paint is a desktop application.

324
00:16:12,420 --> 00:16:14,940
So all these comes under desktop applications.

325
00:16:14,940 --> 00:16:18,180
So these are all comes under application software

326
00:16:18,180 --> 00:16:21,140
because as a user, I can use these applications.

327
00:16:21,140 --> 00:16:23,140
I can use this software,

328
00:16:23,140 --> 00:16:25,820
but I cannot directly use programming software

329
00:16:26,420 --> 00:16:27,260
and system software

330
00:16:27,260 --> 00:16:29,140
because these are the internal softwares

331
00:16:29,140 --> 00:16:31,100
which we cannot see them.

332
00:16:31,100 --> 00:16:34,780
But these softwares are used to run your systems.

333
00:16:34,780 --> 00:16:39,780
But application software, we have to use on daily usage.

334
00:16:39,780 --> 00:16:41,140
And we can do some tasks

335
00:16:41,140 --> 00:16:43,700
by using these application softwares.

336
00:16:43,700 --> 00:16:46,180
Okay, suppose if you go for amazon.com.

337
00:16:46,180 --> 00:16:47,540
So that is an online application.

338
00:16:47,540 --> 00:16:48,740
That is a software.

339
00:16:48,740 --> 00:16:51,460
What we can do, we can search for the product.

340
00:16:51,460 --> 00:16:53,640
We can add to cart and we can do the payment.

341
00:16:53,640 --> 00:16:55,740
So these are activities we can do.

342
00:16:56,580 --> 00:16:59,740
Similarly, banking applications, financial applications.

343
00:16:59,740 --> 00:17:01,900
So educational institution applications.

344
00:17:01,900 --> 00:17:03,740
So all these comes under web applications,

345
00:17:03,740 --> 00:17:05,180
mobile apps, desktop applications.

346
00:17:05,180 --> 00:17:07,460
So every day on day-to-day basis,

347
00:17:07,460 --> 00:17:09,460
we are working with these applications.

348
00:17:09,460 --> 00:17:12,860
So these are all comes under application software.

349
00:17:12,860 --> 00:17:16,820
Our testing is also mainly focused on application software.

350
00:17:16,820 --> 00:17:19,940
We are going to test the application softwares.

351
00:17:19,940 --> 00:17:22,700
Okay, so this is basically understanding

352
00:17:22,700 --> 00:17:25,420
the basic understanding of what is software,

353
00:17:25,460 --> 00:17:27,420
the types of software.

354
00:17:27,420 --> 00:17:31,740
Okay, so the next thing is, what is software testing?

355
00:17:31,740 --> 00:17:34,060
So we understood what is software testing,

356
00:17:34,060 --> 00:17:36,020
software types of software testing.

357
00:17:36,020 --> 00:17:39,500
Now we need to understand what is software testing.

358
00:17:40,280 --> 00:17:41,980
Okay, so next one, what is software testing.

359
00:17:41,980 --> 00:17:43,660
We already know what is software.

360
00:17:43,660 --> 00:17:46,300
Now we need to understand what is software testing.

361
00:17:46,300 --> 00:17:49,000
And then why the software testing is required.

362
00:17:49,960 --> 00:17:52,900
So this is one of the important, interest question also.

363
00:17:52,900 --> 00:17:54,500
Like what is a software testing.

364
00:17:55,780 --> 00:18:00,700
So normally, when you purchase any product, right?

365
00:18:00,700 --> 00:18:02,420
So what you will do,

366
00:18:02,420 --> 00:18:04,940
you will do some basic functionalities working or not.

367
00:18:04,940 --> 00:18:07,860
So let me just give you one example.

368
00:18:07,860 --> 00:18:11,380
Suppose you want to buy a mobile.

369
00:18:11,380 --> 00:18:13,740
Okay, so before buying a mobile,

370
00:18:13,740 --> 00:18:16,820
you will have some budget, okay?

371
00:18:16,820 --> 00:18:19,140
And with that budget, within that budget,

372
00:18:19,140 --> 00:18:22,380
you are expecting some features to be there in your mobile.

373
00:18:22,380 --> 00:18:23,660
Okay, you have some budget

374
00:18:23,660 --> 00:18:25,620
and you are expecting some features.

375
00:18:25,620 --> 00:18:28,220
Some functionality should be there in your mobile.

376
00:18:28,220 --> 00:18:29,580
And with that input,

377
00:18:29,580 --> 00:18:33,340
you are searching for different brands in a market.

378
00:18:33,340 --> 00:18:36,460
And finally, you search some brand and some model

379
00:18:36,460 --> 00:18:39,520
and you bought it, okay?

380
00:18:39,520 --> 00:18:41,100
And you spend some budget

381
00:18:41,100 --> 00:18:42,660
and also you're expecting something

382
00:18:42,660 --> 00:18:45,060
should be there in your mobile.

383
00:18:45,060 --> 00:18:47,140
And once you bought your phone,

384
00:18:47,140 --> 00:18:49,260
you started using your mobile

385
00:18:49,260 --> 00:18:52,780
and then you started finding some bugs

386
00:18:52,780 --> 00:18:53,820
or issues in your mobile.

387
00:18:53,820 --> 00:18:55,420
So something is not working

388
00:18:55,420 --> 00:18:58,140
or on or off is not properly working, right?

389
00:18:58,140 --> 00:18:59,860
Our screen is not properly appearing.

390
00:18:59,860 --> 00:19:02,320
Some apps are striking.

391
00:19:02,320 --> 00:19:05,140
So if you find these kinds of issues in your mobile,

392
00:19:05,140 --> 00:19:06,760
how you will feel,

393
00:19:06,760 --> 00:19:09,360
definitely you will start frustrating with that product,

394
00:19:09,360 --> 00:19:10,200
right?

395
00:19:10,200 --> 00:19:12,180
So why these things, this thing is happened

396
00:19:12,180 --> 00:19:15,920
because of lacking of testing.

397
00:19:15,920 --> 00:19:18,860
Because you bought a mobile, you bought a product,

398
00:19:18,860 --> 00:19:20,560
but this is buggy product.

399
00:19:20,560 --> 00:19:22,540
So you have some issues with that product.

400
00:19:22,540 --> 00:19:24,020
Why these issues are there in the product?

401
00:19:24,020 --> 00:19:27,620
Because testing is not properly conducted, right?

402
00:19:27,620 --> 00:19:29,220
Each and every function,

403
00:19:29,220 --> 00:19:32,260
each and every feature is properly working or not.

404
00:19:32,260 --> 00:19:34,140
It is not properly tested.

405
00:19:34,140 --> 00:19:36,860
So that is the reason you start frustrating

406
00:19:36,860 --> 00:19:38,620
with that product, right?

407
00:19:38,620 --> 00:19:41,500
Same thing will happen with the software also.

408
00:19:41,500 --> 00:19:44,180
Same thing will happen with the software also.

409
00:19:44,180 --> 00:19:45,580
But who is using software?

410
00:19:45,580 --> 00:19:49,220
So for example, let us say some bank, okay?

411
00:19:49,220 --> 00:19:52,440
So let's say I have something called xBank.

412
00:19:52,440 --> 00:19:55,000
So this bank is doing some transaction

413
00:19:55,000 --> 00:19:57,620
on day-to-day basis manually.

414
00:19:57,620 --> 00:19:59,360
And after a few days,

415
00:19:59,360 --> 00:20:04,200
this particular bank wanted to automate the process.

416
00:20:04,200 --> 00:20:05,560
The bank automate,

417
00:20:05,560 --> 00:20:08,760
the bank, this particular bank wanted to automate the process.

418
00:20:08,760 --> 00:20:09,920
Means what?

419
00:20:09,920 --> 00:20:12,560
Whatever the transactions they are doing manually,

420
00:20:12,560 --> 00:20:16,320
they want a software and using that software,

421
00:20:16,320 --> 00:20:19,520
they wanted to do those tasks, okay?

422
00:20:19,520 --> 00:20:21,000
Through the software.

423
00:20:21,000 --> 00:20:22,160
And what this bank?

424
00:20:22,800 --> 00:20:23,640
So bank is nothing but what?

425
00:20:23,640 --> 00:20:26,840
This is a small company, okay?

426
00:20:26,840 --> 00:20:28,840
And this particular company or bank

427
00:20:28,840 --> 00:20:32,520
will approach an IT company, okay?

428
00:20:32,520 --> 00:20:34,260
Will approach an IT company.

429
00:20:35,340 --> 00:20:38,200
And once they approach this IT company,

430
00:20:38,200 --> 00:20:40,520
they will explain their requirement.

431
00:20:40,520 --> 00:20:43,400
So what exactly they do in their organization.

432
00:20:43,400 --> 00:20:46,600
So what kind of operations or actions or tasks they do

433
00:20:46,600 --> 00:20:49,020
on day-to-day basis in their organization.

434
00:20:49,020 --> 00:20:50,880
So they will explain the entire,

435
00:20:50,880 --> 00:20:52,560
the process, the requirement,

436
00:20:52,560 --> 00:20:54,540
everything into this IT company.

437
00:20:55,440 --> 00:20:57,840
Along with that, the budget,

438
00:20:57,840 --> 00:21:00,040
what is the budget they have

439
00:21:00,040 --> 00:21:03,240
and within what time they need the software.

440
00:21:03,240 --> 00:21:06,340
So all these things will be explained to this IT company.

441
00:21:07,220 --> 00:21:09,280
Now, what IT company will do is,

442
00:21:09,280 --> 00:21:14,000
IT company will review and understand their requirement

443
00:21:14,000 --> 00:21:16,000
and their budget and time.

444
00:21:16,000 --> 00:21:18,000
So by considering them,

445
00:21:18,000 --> 00:21:21,000
they will agree to develop the software

446
00:21:21,000 --> 00:21:24,040
which will fulfill their tasks, okay?

447
00:21:24,040 --> 00:21:25,760
Instead of doing manual transaction,

448
00:21:25,760 --> 00:21:29,220
they can do automate using particular software.

449
00:21:29,220 --> 00:21:32,920
And so after reviewing those requirements by IT company,

450
00:21:32,920 --> 00:21:36,640
they agree to develop a software, okay?

451
00:21:36,640 --> 00:21:38,240
And what IT company will do now,

452
00:21:38,240 --> 00:21:41,920
IT company will develop the software,

453
00:21:41,920 --> 00:21:46,920
will develop the software and it also to be tested, okay?

454
00:21:47,080 --> 00:21:49,920
Test the software and after testing,

455
00:21:49,920 --> 00:21:54,920
then deliver the software to the company called xBank.

456
00:21:55,440 --> 00:21:57,380
So this is actual process.

457
00:21:57,380 --> 00:22:01,480
So some company will approach the IT company

458
00:22:01,480 --> 00:22:05,160
by saying all their requirement, budget and time.

459
00:22:05,160 --> 00:22:09,520
And based on that, IT company will agree the requirement,

460
00:22:09,520 --> 00:22:10,440
agrees the proposal

461
00:22:10,440 --> 00:22:13,160
and then they start developing the software

462
00:22:13,160 --> 00:22:14,800
and they will recruit some number of people,

463
00:22:14,800 --> 00:22:17,920
developers, testers, designers, program managers,

464
00:22:17,920 --> 00:22:19,240
all these people.

465
00:22:19,240 --> 00:22:22,040
And they take some time to develop the software.

466
00:22:22,040 --> 00:22:26,600
And then finally, before delivering the software to the bank,

467
00:22:26,600 --> 00:22:29,400
we have to conduct the testing here.

468
00:22:29,400 --> 00:22:32,520
So after development, testing comes into picture.

469
00:22:32,520 --> 00:22:34,060
So why we need to do the testing?

470
00:22:34,060 --> 00:22:35,520
What is testing here?

471
00:22:35,520 --> 00:22:37,080
Why we are conducting testing here?

472
00:22:37,080 --> 00:22:41,100
Because we have to release the quality product

473
00:22:41,100 --> 00:22:42,120
to the customer.

474
00:22:42,120 --> 00:22:44,880
We have to deliver the quality product to the customer.

475
00:22:44,880 --> 00:22:49,620
So that is the main intention of doing software testing, okay?

476
00:22:49,620 --> 00:22:53,460
So software testing will play very, very important role

477
00:22:53,460 --> 00:22:56,200
because if you deliver the buggy product to the customer,

478
00:22:56,200 --> 00:22:57,280
it'll start frustrating it

479
00:22:57,280 --> 00:23:01,280
because he spent a lot of budget, a lot of time, right?

480
00:23:01,280 --> 00:23:05,840
So this is our responsibility, the company responsibility

481
00:23:05,840 --> 00:23:09,200
to provide the quality product to the customer.

482
00:23:09,200 --> 00:23:11,440
It should not have any bugs.

483
00:23:11,440 --> 00:23:14,920
It should work according to customer requirement.

484
00:23:14,920 --> 00:23:17,560
So all these things we have to take care

485
00:23:17,560 --> 00:23:21,520
while performing the testing, the software, okay?

486
00:23:21,520 --> 00:23:23,060
So what is software testing?

487
00:23:23,060 --> 00:23:25,440
So software testing is very, very important

488
00:23:25,440 --> 00:23:29,120
before delivering the software to the customer, okay?

489
00:23:29,120 --> 00:23:30,820
Now, what is software testing?

490
00:23:30,820 --> 00:23:35,000
The software testing is a part of software development.

491
00:23:35,000 --> 00:23:36,600
Here, development means what?

492
00:23:36,600 --> 00:23:38,680
Not only writing the code, okay?

493
00:23:38,680 --> 00:23:40,640
We have to test the software,

494
00:23:40,640 --> 00:23:42,040
whether it is working according

495
00:23:42,040 --> 00:23:43,780
to customer requirement or not.

496
00:23:43,780 --> 00:23:46,440
If you're not conducting testing, what happens?

497
00:23:46,440 --> 00:23:48,920
Definitely the product is having some bugs

498
00:23:48,920 --> 00:23:51,200
because there is no guarantee

499
00:23:51,200 --> 00:23:54,040
like developers will do everything perfectly fine, right?

500
00:23:54,040 --> 00:23:55,080
There should be some bugs.

501
00:23:55,080 --> 00:23:57,060
There will be some gaps.

502
00:23:57,060 --> 00:23:59,320
So we have to test the software.

503
00:23:59,320 --> 00:24:01,320
We need to identify the bugs

504
00:24:01,320 --> 00:24:03,600
and the developers again will fix those bugs.

505
00:24:03,600 --> 00:24:06,300
And finally, we will deliver the quality product

506
00:24:06,300 --> 00:24:09,000
to the customer, okay?

507
00:24:09,000 --> 00:24:13,080
So the testing is a part of the development process.

508
00:24:13,080 --> 00:24:15,000
We'll understand the customer requirement.

509
00:24:15,000 --> 00:24:18,080
We will design it, then coding, then testing,

510
00:24:18,080 --> 00:24:20,720
and finally delivering the software to the customer.

511
00:24:20,720 --> 00:24:22,860
So these things will come into picture.

512
00:24:22,860 --> 00:24:27,160
So now, if I just look at what is software testing,

513
00:24:27,160 --> 00:24:28,820
let me write some notes here.

514
00:24:31,520 --> 00:24:36,040
So what is software?

515
00:24:36,040 --> 00:24:37,780
We understood what is software.

516
00:24:37,780 --> 00:24:40,980
Now we are understanding what is software testing.

517
00:24:40,980 --> 00:24:43,440
So software testing is a part

518
00:24:43,440 --> 00:24:45,620
of software development process.

519
00:24:46,820 --> 00:24:50,500
Software testing is an activity to detect

520
00:24:50,500 --> 00:24:52,620
and identify the defects in the software.

521
00:24:52,620 --> 00:24:55,040
So this is the main intention of the tester.

522
00:24:55,040 --> 00:24:56,940
What is the job of tester means?

523
00:24:56,940 --> 00:24:59,300
He has to identify the defects

524
00:24:59,300 --> 00:25:02,220
and he has to make sure our application

525
00:25:02,220 --> 00:25:04,060
or software is working according

526
00:25:04,060 --> 00:25:06,020
to customer requirement or not.

527
00:25:06,020 --> 00:25:07,780
Because initially customer will provide you

528
00:25:07,780 --> 00:25:10,500
some requirement, the functionality.

529
00:25:10,500 --> 00:25:13,260
And our software also should perform the same thing,

530
00:25:13,260 --> 00:25:14,980
whatever the customer is expecting.

531
00:25:15,940 --> 00:25:17,980
Suppose the customer is said something

532
00:25:17,980 --> 00:25:20,580
and we develop the software for something else.

533
00:25:20,580 --> 00:25:22,020
It doesn't work, right?

534
00:25:22,020 --> 00:25:25,660
So the main intention of software testing is

535
00:25:25,660 --> 00:25:29,220
it is a activity to detect and identify the defects.

536
00:25:29,220 --> 00:25:31,860
We have to execute some test cases.

537
00:25:31,860 --> 00:25:33,060
I'll tell you what is the test case

538
00:25:33,060 --> 00:25:34,340
and how to execute all these things.

539
00:25:34,340 --> 00:25:36,300
So the main intention of software testing is

540
00:25:36,300 --> 00:25:40,920
we have to find the defects in the software, okay?

541
00:25:40,920 --> 00:25:43,900
And the main objective is to release the quality product

542
00:25:43,900 --> 00:25:46,340
to the client or customer.

543
00:25:46,340 --> 00:25:49,160
So this is basically what is software testing.

544
00:25:49,160 --> 00:25:52,020
So testing is a part of software development.

545
00:25:52,020 --> 00:25:55,760
Testing is an activity to find the defects in the software.

546
00:25:55,760 --> 00:25:57,780
The main objective of testing is

547
00:25:57,780 --> 00:26:01,780
to release a quality product to the customer or client.

548
00:26:01,780 --> 00:26:06,740
So this is all about what is software testing.

549
00:26:06,740 --> 00:26:08,780
The next one is what is quality.

550
00:26:08,780 --> 00:26:11,700
So here we are talking about the quality.

551
00:26:11,700 --> 00:26:12,620
What is quality?

552
00:26:13,660 --> 00:26:15,100
Every day we are talking about quality.

553
00:26:15,100 --> 00:26:16,100
If I buy something,

554
00:26:16,100 --> 00:26:18,460
we are always expecting the quality, right?

555
00:26:18,460 --> 00:26:20,420
But what exactly quality means?

556
00:26:20,420 --> 00:26:21,940
The main objective of testing is

557
00:26:21,940 --> 00:26:23,620
to release quality product to the client.

558
00:26:23,620 --> 00:26:24,780
But what is quality?

559
00:26:26,180 --> 00:26:27,100
So what is quality?

560
00:26:27,100 --> 00:26:31,100
So quality is something called customer justification.

561
00:26:31,100 --> 00:26:34,300
So how well our product or software is working,

562
00:26:35,220 --> 00:26:37,820
the customer will decide, okay?

563
00:26:37,820 --> 00:26:41,700
So here there are some parameter based on that we can say

564
00:26:41,700 --> 00:26:44,340
whether our software is quality or not,

565
00:26:44,340 --> 00:26:45,600
quality software or not.

566
00:26:45,600 --> 00:26:47,660
So what are those parameters?

567
00:26:47,660 --> 00:26:48,920
Let me just tell you.

568
00:26:48,920 --> 00:26:50,340
So software quality.

569
00:26:51,860 --> 00:26:53,740
So these are all very important guys,

570
00:26:53,740 --> 00:26:54,980
so beginner as a beginner.

571
00:26:54,980 --> 00:26:57,420
So please try to understand this.

572
00:26:57,420 --> 00:27:01,300
Very simple terms, software quality.

573
00:27:01,300 --> 00:27:03,140
So why we are discussing software quality

574
00:27:03,140 --> 00:27:05,900
because our ultimate goal of testing is

575
00:27:05,900 --> 00:27:10,380
to deliver the quality product to the customer or client.

576
00:27:10,380 --> 00:27:12,180
But what is software quality?

577
00:27:12,180 --> 00:27:13,460
So software quality,

578
00:27:13,460 --> 00:27:17,140
if I say a product or software is very quality product,

579
00:27:17,140 --> 00:27:21,340
I can say based on certain parameters, okay?

580
00:27:21,340 --> 00:27:23,580
So what are those parameters?

581
00:27:23,580 --> 00:27:27,500
So the first parameter is bug free.

582
00:27:27,500 --> 00:27:29,020
So based on these parameters,

583
00:27:29,020 --> 00:27:33,100
we can say our software is quality software or not.

584
00:27:33,100 --> 00:27:36,280
The first parameter is bug free.

585
00:27:36,280 --> 00:27:38,220
What is meant by bug free?

586
00:27:38,220 --> 00:27:41,780
So our software should not have any bugs,

587
00:27:41,780 --> 00:27:46,780
but 900% software, 100% software will not be bug free guys,

588
00:27:48,040 --> 00:27:50,220
but at least one or 2%, there will be bugs,

589
00:27:50,220 --> 00:27:52,140
but they are very, very minor bugs.

590
00:27:52,180 --> 00:27:53,860
The customer process or task

591
00:27:53,860 --> 00:27:55,900
will not be impacted by those bugs.

592
00:27:55,900 --> 00:27:58,400
But 100% quality product

593
00:27:58,400 --> 00:28:03,400
cannot be always possible to release to the customer, okay?

594
00:28:04,500 --> 00:28:06,380
It is not at all possible.

595
00:28:06,380 --> 00:28:08,420
At least one or 2% bugs will be there,

596
00:28:08,420 --> 00:28:10,720
but they are very minor bugs.

597
00:28:10,720 --> 00:28:12,820
We can ignore those bugs, okay?

598
00:28:12,820 --> 00:28:15,100
And the final thing,

599
00:28:15,100 --> 00:28:16,380
the objective of testing is

600
00:28:16,380 --> 00:28:18,540
to release the quality product to the client.

601
00:28:18,540 --> 00:28:21,160
But what is the software quality?

602
00:28:21,160 --> 00:28:23,960
So software quality can be measured.

603
00:28:23,960 --> 00:28:26,960
So later I'll tell you what are the metrics we have to use,

604
00:28:26,960 --> 00:28:30,480
but mainly we can say software is a quality

605
00:28:30,480 --> 00:28:32,800
based on certain parameters.

606
00:28:32,800 --> 00:28:35,840
So the first parameter will be the bug free.

607
00:28:35,840 --> 00:28:38,900
The software should not contain any bugs.

608
00:28:38,900 --> 00:28:40,200
That's the first thing.

609
00:28:40,200 --> 00:28:43,000
Second thing, delivered on time.

610
00:28:43,000 --> 00:28:45,000
So I said before,

611
00:28:45,000 --> 00:28:48,660
when an IT company is approaching the IT company,

612
00:28:48,660 --> 00:28:51,940
so some X company is approaching the IT company,

613
00:28:51,940 --> 00:28:55,900
they have some budget and they have some time also.

614
00:28:55,900 --> 00:28:58,700
Within that time, we have to develop and test the software

615
00:28:58,700 --> 00:29:02,240
and we have to deliver the software to the company, right?

616
00:29:02,240 --> 00:29:06,140
And they spend some budget and also time.

617
00:29:06,140 --> 00:29:08,260
Suppose what happens,

618
00:29:08,260 --> 00:29:10,380
suppose development and testing is taken

619
00:29:10,380 --> 00:29:14,120
more than the committed time, then what happens?

620
00:29:14,120 --> 00:29:16,820
We have to pay to the staff also, right?

621
00:29:16,820 --> 00:29:19,660
We have to spend a lot of time, right?

622
00:29:19,660 --> 00:29:23,740
So what happens if you're not able to deliver the software

623
00:29:23,740 --> 00:29:28,140
within the time or on time, that is also considerable

624
00:29:28,140 --> 00:29:31,220
because the customer has to spend more budget

625
00:29:31,220 --> 00:29:33,020
because automatically the time is increased,

626
00:29:33,020 --> 00:29:35,420
increase like duration is increased automatically.

627
00:29:35,420 --> 00:29:37,940
You have to spend money on the staff also, right?

628
00:29:37,940 --> 00:29:39,780
Employees like developers, testers,

629
00:29:39,780 --> 00:29:41,440
who is working on that project,

630
00:29:41,440 --> 00:29:43,320
we have to pay to them, right?

631
00:29:43,320 --> 00:29:46,020
If suppose time is increased.

632
00:29:46,020 --> 00:29:48,040
So deliver on time.

633
00:29:48,040 --> 00:29:49,460
So not only back free,

634
00:29:49,460 --> 00:29:52,500
we should also deliver the software on time.

635
00:29:52,500 --> 00:29:54,180
That is one parameter.

636
00:29:54,180 --> 00:29:56,420
The third parameter is within the budget.

637
00:29:56,420 --> 00:30:00,620
Sometimes some organization will have some budget

638
00:30:00,620 --> 00:30:03,440
and once you start developing and testing,

639
00:30:03,440 --> 00:30:05,580
the budget will be increased.

640
00:30:05,580 --> 00:30:07,380
That should not be happen.

641
00:30:07,380 --> 00:30:12,380
So whatever the time and budget they have mentioned initially,

642
00:30:12,500 --> 00:30:15,940
we have to deliver the software within that particular time

643
00:30:16,860 --> 00:30:18,660
and within that particular budget.

644
00:30:18,660 --> 00:30:22,060
And then only the customer will say our product

645
00:30:22,060 --> 00:30:25,860
or our software is quality and not only back free

646
00:30:25,860 --> 00:30:29,180
and it is also depends on other factors.

647
00:30:29,180 --> 00:30:31,060
And it should be delivered on time

648
00:30:31,060 --> 00:30:33,140
and it should be within the budget.

649
00:30:33,140 --> 00:30:36,260
And finally, it should meet the requirements

650
00:30:36,260 --> 00:30:39,140
or expectations from the customer, okay?

651
00:30:39,140 --> 00:30:41,020
So whatever software we develop,

652
00:30:41,020 --> 00:30:43,860
that should fulfill the requirement of customers.

653
00:30:43,860 --> 00:30:46,620
So that's the first and most important task.

654
00:30:46,620 --> 00:30:48,340
Customers set some requirement

655
00:30:48,340 --> 00:30:50,140
and we have developed and tested software.

656
00:30:50,140 --> 00:30:53,180
It should work according to their requirement.

657
00:30:53,180 --> 00:30:54,660
So this is very, very important.

658
00:30:54,660 --> 00:30:57,060
It should meet the requirements

659
00:30:57,060 --> 00:31:00,020
or expectations from the customer.

660
00:31:00,020 --> 00:31:02,740
And finally, it should be maintainable.

661
00:31:02,740 --> 00:31:04,340
Maintainable means what?

662
00:31:04,340 --> 00:31:07,540
After installing our software in the customer environment,

663
00:31:07,540 --> 00:31:09,780
they should be able to work with that.

664
00:31:09,780 --> 00:31:11,860
And if there is any small issues,

665
00:31:11,860 --> 00:31:14,220
they should be able to resolve themself

666
00:31:14,220 --> 00:31:17,100
and should be user friendly, okay?

667
00:31:17,100 --> 00:31:20,020
In that case, we can say it is a maintainable.

668
00:31:20,020 --> 00:31:23,180
So when I deliver a software to the customer,

669
00:31:23,180 --> 00:31:27,340
if our software is fulfilling all these parameters,

670
00:31:27,340 --> 00:31:29,980
we can say which is a quality product

671
00:31:29,980 --> 00:31:33,420
or which is a quality software.

672
00:31:33,420 --> 00:31:36,460
And to make sure all these things should be there,

673
00:31:36,460 --> 00:31:38,980
we have to conduct our testing.

674
00:31:38,980 --> 00:31:40,580
So the main intention of testing

675
00:31:40,860 --> 00:31:43,740
is to deliver the quality product to the customer.

676
00:31:43,740 --> 00:31:46,940
And when we say our product or software is a quality,

677
00:31:46,940 --> 00:31:48,300
having some quality means

678
00:31:48,300 --> 00:31:50,980
which we have to follow these parameters.

679
00:31:50,980 --> 00:31:54,460
It should be, it doesn't have any bugs.

680
00:31:54,460 --> 00:31:58,100
You can say bug free and it should be delivered on time.

681
00:31:58,100 --> 00:32:00,940
It should be delivered within the budget

682
00:32:00,940 --> 00:32:03,780
and it should also meet customer requirements

683
00:32:03,780 --> 00:32:06,140
or it should work according to the customer requirements

684
00:32:06,140 --> 00:32:07,380
or expectation.

685
00:32:07,380 --> 00:32:09,580
And finally, it should be maintainable

686
00:32:09,580 --> 00:32:11,780
in their environment, okay?

687
00:32:11,780 --> 00:32:14,620
So these are the main quality standards.

688
00:32:14,620 --> 00:32:16,780
So if I say software is a quality software,

689
00:32:16,780 --> 00:32:20,540
then we have to follow these parameters, okay?

690
00:32:20,540 --> 00:32:24,540
Now here, I'm just using some terms continuous

691
00:32:24,540 --> 00:32:26,900
like project and product.

692
00:32:26,900 --> 00:32:28,820
And these terms are very, very important.

693
00:32:28,820 --> 00:32:31,180
We need to understand as a beginner.

694
00:32:31,180 --> 00:32:33,100
So what is project and product?

695
00:32:34,260 --> 00:32:35,380
Project and product.

696
00:32:35,380 --> 00:32:37,380
So people are sometimes using project.

697
00:32:37,380 --> 00:32:38,740
Sometimes they say product.

698
00:32:38,740 --> 00:32:40,780
What is project and product?

699
00:32:40,780 --> 00:32:42,140
And even in the companies also,

700
00:32:42,140 --> 00:32:43,420
there are two kinds of companies

701
00:32:43,420 --> 00:32:47,060
like service-based companies, product-based companies.

702
00:32:47,060 --> 00:32:49,540
Similarly, we have a project and products.

703
00:32:49,540 --> 00:32:51,260
So what exactly project means?

704
00:32:51,260 --> 00:32:53,260
What exactly product means?

705
00:32:53,260 --> 00:32:56,500
There is a small difference between project and product.

706
00:32:56,500 --> 00:32:58,260
So you have to understand these terminology

707
00:32:58,260 --> 00:33:02,300
which is very important before going to testing part.

708
00:33:03,300 --> 00:33:04,140
Okay.

709
00:33:05,140 --> 00:33:09,660
Let me tell you what is project and product.

710
00:33:09,660 --> 00:33:10,780
Project and product.

711
00:33:11,900 --> 00:33:14,180
Okay, so let me write some notes here.

712
00:33:15,300 --> 00:33:17,100
Very small difference, guys.

713
00:33:17,100 --> 00:33:20,700
The first one is if software application.

714
00:33:20,700 --> 00:33:23,900
So whatever software we developed and tested,

715
00:33:23,900 --> 00:33:28,060
which is for specific customer based on the requirement,

716
00:33:28,060 --> 00:33:29,860
then it is called as a project.

717
00:33:29,940 --> 00:33:31,140
Means what?

718
00:33:31,140 --> 00:33:32,860
We approach a customer.

719
00:33:32,860 --> 00:33:35,460
Customer will give you specific customer

720
00:33:35,460 --> 00:33:38,060
and customer will give you the requirement.

721
00:33:38,060 --> 00:33:40,140
Customer will spend some budget.

722
00:33:40,140 --> 00:33:41,420
They will give the requirement

723
00:33:41,420 --> 00:33:42,940
and we will develop the software

724
00:33:42,940 --> 00:33:45,820
according to that particular customer.

725
00:33:45,820 --> 00:33:49,140
So whatever software we developed and tested

726
00:33:49,140 --> 00:33:52,500
according to the specific customer requirement,

727
00:33:52,500 --> 00:33:54,780
we can simply say that is a project.

728
00:33:55,780 --> 00:33:57,100
Project means what?

729
00:33:57,140 --> 00:33:59,420
The application or a software

730
00:33:59,420 --> 00:34:03,180
which is developed for specific customer requirement.

731
00:34:03,180 --> 00:34:07,380
And that software will be used by the customer himself.

732
00:34:07,380 --> 00:34:09,220
Others cannot be used.

733
00:34:09,220 --> 00:34:13,940
Okay, suppose I develop a software for an organization

734
00:34:13,940 --> 00:34:17,580
and only that organization can be used in that software

735
00:34:17,580 --> 00:34:20,180
and other organizations cannot be used.

736
00:34:20,180 --> 00:34:22,620
And those things called as a project.

737
00:34:22,620 --> 00:34:25,100
A project is a software application

738
00:34:25,100 --> 00:34:28,020
which is developed for specific customer

739
00:34:28,020 --> 00:34:32,260
based on the requirement, then it is called project.

740
00:34:32,260 --> 00:34:34,220
Okay, if the software application is developed

741
00:34:34,220 --> 00:34:38,220
for specific customer based on the requirement,

742
00:34:38,220 --> 00:34:40,020
based on the customer requirement,

743
00:34:40,020 --> 00:34:42,100
then it is called as a project.

744
00:34:42,100 --> 00:34:45,300
And only the specific customer can use this.

745
00:34:45,300 --> 00:34:47,700
But what is a product means?

746
00:34:47,700 --> 00:34:50,140
If the software application is developed

747
00:34:50,140 --> 00:34:53,620
for multiple customers based on market requirement,

748
00:34:53,620 --> 00:34:55,740
then it is called as a product.

749
00:34:55,740 --> 00:34:57,060
That means what?

750
00:34:57,060 --> 00:34:59,900
We will collect the requirements from the market,

751
00:34:59,900 --> 00:35:02,140
not from the specific customer.

752
00:35:02,140 --> 00:35:04,700
Okay, what is exactly market requirements?

753
00:35:04,700 --> 00:35:08,420
We will analyze them and we will develop a software.

754
00:35:08,420 --> 00:35:09,900
Then we'll deliver it to the market.

755
00:35:09,900 --> 00:35:10,860
And number of people,

756
00:35:10,860 --> 00:35:13,460
number of customers are using that software.

757
00:35:13,460 --> 00:35:16,380
In that case, which is called as a product.

758
00:35:16,380 --> 00:35:17,780
A product is a software

759
00:35:17,780 --> 00:35:20,940
which can be used by multiple customers.

760
00:35:20,940 --> 00:35:22,260
Project is a software

761
00:35:22,260 --> 00:35:25,180
which can be used by specific customer.

762
00:35:25,180 --> 00:35:27,340
Okay, project is a software

763
00:35:27,340 --> 00:35:29,260
which can be used by specific customer.

764
00:35:29,260 --> 00:35:32,500
We are developing it for specific customer requirement.

765
00:35:32,500 --> 00:35:34,380
Whereas product is a software

766
00:35:34,380 --> 00:35:36,860
which we can develop for market

767
00:35:36,860 --> 00:35:39,060
or based on market requirements.

768
00:35:39,060 --> 00:35:40,740
So what are the examples?

769
00:35:40,740 --> 00:35:43,260
For example, there is a bank.

770
00:35:43,260 --> 00:35:46,420
Okay, and I have developed a software

771
00:35:46,420 --> 00:35:48,940
which can do all the transactions automated

772
00:35:49,900 --> 00:35:50,940
in that particular bank.

773
00:35:50,940 --> 00:35:52,620
So that is project

774
00:35:52,620 --> 00:35:55,460
because that application or software can be used

775
00:35:55,460 --> 00:35:58,180
only within that bank, within that particular organization.

776
00:35:58,180 --> 00:35:59,820
Others cannot be used.

777
00:35:59,820 --> 00:36:02,220
So they are called projects.

778
00:36:02,220 --> 00:36:03,700
And what is a product means?

779
00:36:03,700 --> 00:36:05,620
Everyone should able to do that.

780
00:36:05,620 --> 00:36:07,780
So for example, in our mobile,

781
00:36:07,780 --> 00:36:09,780
there are so many apps will be there.

782
00:36:09,780 --> 00:36:10,940
Let's say WhatsApp.

783
00:36:10,940 --> 00:36:14,140
So WhatsApp is an application, a software application

784
00:36:14,140 --> 00:36:16,020
and everybody using it.

785
00:36:16,020 --> 00:36:18,340
So that is an example of product.

786
00:36:18,340 --> 00:36:22,100
And suppose our Microsoft products, Word, Excel, PowerPoint.

787
00:36:22,100 --> 00:36:25,620
So these are all the softwares and everybody using them

788
00:36:25,620 --> 00:36:27,940
and how they develop those softwares

789
00:36:27,940 --> 00:36:30,100
based on the customer requirement.

790
00:36:30,100 --> 00:36:32,020
And they'll analyze the requirement from the market,

791
00:36:32,020 --> 00:36:33,500
from the people,

792
00:36:33,500 --> 00:36:35,340
and they'll consolidate all the requirements.

793
00:36:35,340 --> 00:36:37,700
Accordingly, they develop the software

794
00:36:37,700 --> 00:36:40,100
and that comes under the product.

795
00:36:40,100 --> 00:36:42,700
So understand this difference, very, very important,

796
00:36:42,700 --> 00:36:44,420
the project and the product.

797
00:36:44,420 --> 00:36:46,900
So project is something which is developed

798
00:36:47,900 --> 00:36:51,540
for specific customer based on their requirement.

799
00:36:51,540 --> 00:36:54,220
And the product is a software which is developed

800
00:36:54,220 --> 00:36:56,220
based on the market requirements

801
00:36:56,220 --> 00:36:57,660
and everybody can use it.

802
00:36:58,540 --> 00:37:00,660
Okay, that is a product.

803
00:37:00,660 --> 00:37:02,460
Now, similarly, the companies also,

804
00:37:02,460 --> 00:37:04,100
two types of companies will be there.

805
00:37:04,100 --> 00:37:07,220
Like service-based companies and product-based companies.

806
00:37:07,220 --> 00:37:09,380
Service-based companies are what?

807
00:37:09,380 --> 00:37:11,980
Most of the times they will deal with the projects.

808
00:37:11,980 --> 00:37:14,060
So they will work for specific customers.

809
00:37:14,060 --> 00:37:16,500
They will work for specific clients.

810
00:37:16,500 --> 00:37:18,140
And those companies are comes under

811
00:37:18,140 --> 00:37:23,140
service-based companies like TCS, Accenture.

812
00:37:23,180 --> 00:37:25,460
Okay, so these companies are comes under

813
00:37:25,460 --> 00:37:28,100
the service-based companies or Infosys.

814
00:37:28,100 --> 00:37:30,020
These are all service-based companies

815
00:37:30,020 --> 00:37:32,740
and they will work for any number of customers

816
00:37:32,740 --> 00:37:36,180
throughout the world and product-based companies.

817
00:37:36,180 --> 00:37:38,180
The other type of companies are we have product.

818
00:37:38,180 --> 00:37:39,660
Product means what?

819
00:37:39,660 --> 00:37:41,380
A software which is developed

820
00:37:41,380 --> 00:37:43,300
based on the market requirements.

821
00:37:43,300 --> 00:37:44,980
So for example, Google.

822
00:37:44,980 --> 00:37:46,740
So Google is a product-based companies.

823
00:37:46,740 --> 00:37:48,900
There are so many Google products out there.

824
00:37:48,900 --> 00:37:51,860
Like Google Max, Google Drive, Gmail.

825
00:37:51,860 --> 00:37:53,940
These are all Google products.

826
00:37:53,940 --> 00:37:55,020
And Microsoft.

827
00:37:55,020 --> 00:37:56,980
Microsoft is also product-based company.

828
00:37:56,980 --> 00:37:59,220
So they will develop the multiple products

829
00:37:59,220 --> 00:38:02,820
on Microsoft products like MS Word, MS Office.

830
00:38:02,820 --> 00:38:05,660
These are all examples of Microsoft products.

831
00:38:05,660 --> 00:38:06,500
And Oracle.

832
00:38:06,500 --> 00:38:09,100
Oracle is also product-based company.

833
00:38:09,100 --> 00:38:11,780
Okay, so there are different type of companies

834
00:38:11,780 --> 00:38:14,580
like service-based companies and product-based companies.

835
00:38:15,580 --> 00:38:20,100
Okay, so that is all about project and product.

836
00:38:24,420 --> 00:38:28,420
Okay, and finally, why we need testing.

837
00:38:28,420 --> 00:38:30,620
We understood what is project and product

838
00:38:30,620 --> 00:38:31,860
and why we need to testing.

839
00:38:31,860 --> 00:38:32,980
So this we already covered.

840
00:38:32,980 --> 00:38:34,860
Why do we need testing?

841
00:38:34,860 --> 00:38:37,300
The ultimate goal is to release

842
00:38:37,300 --> 00:38:38,940
a quality product to the customer.

843
00:38:38,940 --> 00:38:41,940
So that's the reason we have to conduct our testing.

844
00:38:41,940 --> 00:38:44,060
And we have to ensure the software

845
00:38:45,020 --> 00:38:46,580
should be bug-free

846
00:38:46,580 --> 00:38:50,420
and it should meet the customer requirements, right?

847
00:38:50,420 --> 00:38:52,940
And also it should work according

848
00:38:52,940 --> 00:38:55,100
to the customer expectation.

849
00:38:55,100 --> 00:38:59,060
So these are the main things which you have to ensure

850
00:38:59,060 --> 00:39:00,420
while conducting the testing.

851
00:39:00,420 --> 00:39:01,900
So without testing, what will happen

852
00:39:01,900 --> 00:39:03,460
if I don't conduct any testing?

853
00:39:03,460 --> 00:39:04,660
Then what happens?

854
00:39:04,660 --> 00:39:06,980
Definitely the software contains the bugs.

855
00:39:06,980 --> 00:39:09,420
And once the customer has started using the software,

856
00:39:09,420 --> 00:39:12,940
definitely they'll first aid it with that.

857
00:39:12,980 --> 00:39:15,700
Okay, so that's the reason we have to conduct our testing.

858
00:39:15,700 --> 00:39:19,460
So we have to ensure the software doesn't have any bugs

859
00:39:19,460 --> 00:39:21,660
and we have to ensure our software is working

860
00:39:21,660 --> 00:39:23,860
according to customer requirement or not.

861
00:39:23,860 --> 00:39:26,780
So these are the two main things which we need to focus

862
00:39:26,780 --> 00:39:28,460
while conducting the software testing.

863
00:39:28,460 --> 00:39:29,500
So why do we need testing?

864
00:39:29,500 --> 00:39:32,340
Means we have to deliver the quality product

865
00:39:32,340 --> 00:39:33,180
to the customer.

866
00:39:33,180 --> 00:39:34,740
So that's the main intention.

867
00:39:36,220 --> 00:39:40,020
Okay, so finally, I'll just explain

868
00:39:40,020 --> 00:39:43,220
about these terms, error, bug and failure.

869
00:39:43,220 --> 00:39:45,460
So a lot of people exactly don't know the difference

870
00:39:45,460 --> 00:39:48,260
between these three and which is very important

871
00:39:48,260 --> 00:39:49,460
to know that.

872
00:39:49,460 --> 00:39:51,180
Error, bug and failure.

873
00:39:51,180 --> 00:39:53,100
Most of the people will think bug is nothing

874
00:39:53,100 --> 00:39:55,300
but some error or some failure.

875
00:39:55,300 --> 00:39:58,420
But there is a small technical differences there.

876
00:39:58,420 --> 00:40:01,220
Error, bug and failure.

877
00:40:01,220 --> 00:40:03,780
Now let me tell you what exactly error means,

878
00:40:03,780 --> 00:40:06,860
what exactly bug means and failure means.

879
00:40:06,860 --> 00:40:09,420
Error is nothing but a human mistake.

880
00:40:09,420 --> 00:40:11,580
If you do some task, right?

881
00:40:11,580 --> 00:40:13,340
If you do some mistake somewhere,

882
00:40:13,340 --> 00:40:16,220
that is basically called as an error, okay?

883
00:40:16,220 --> 00:40:18,260
It is an incorrect human action.

884
00:40:18,260 --> 00:40:20,700
We can simply say an incorrect human action

885
00:40:20,700 --> 00:40:22,580
is called an error.

886
00:40:22,580 --> 00:40:26,620
So suppose as a developer, he's writing some program

887
00:40:26,620 --> 00:40:29,580
and he has committed some, by mistake,

888
00:40:29,580 --> 00:40:33,860
he has typed something else and that is causing the error.

889
00:40:33,860 --> 00:40:38,260
So error is basically human mistake, okay?

890
00:40:38,260 --> 00:40:40,820
And bug, what is the bug?

891
00:40:40,820 --> 00:40:43,620
Bug is nothing but it is a deviation

892
00:40:43,620 --> 00:40:45,900
of expecting actual results.

893
00:40:45,900 --> 00:40:49,620
So for example, there is a simple,

894
00:40:49,620 --> 00:40:53,060
let's say login screen in your application, right?

895
00:40:53,060 --> 00:40:56,500
So when I provide a valid username and valid password,

896
00:40:56,500 --> 00:40:58,620
I should able to log into my application.

897
00:40:58,620 --> 00:41:00,420
Let's say Gmail application.

898
00:41:01,300 --> 00:41:02,940
So how to log into Gmail?

899
00:41:02,940 --> 00:41:05,620
I have to provide the valid username and valid password.

900
00:41:05,620 --> 00:41:08,020
So when I provide valid username and valid password,

901
00:41:08,020 --> 00:41:10,260
then I should able to successfully log in.

902
00:41:11,300 --> 00:41:13,140
But, and similarly, if I want to pass,

903
00:41:13,140 --> 00:41:16,340
let's say if I pass invalid username and invalid password,

904
00:41:16,340 --> 00:41:18,580
I should not able to log in.

905
00:41:18,580 --> 00:41:20,740
But what happening, even though if I providing

906
00:41:20,740 --> 00:41:22,660
invalid username and password,

907
00:41:22,660 --> 00:41:25,540
an application is allowing me to log in.

908
00:41:25,540 --> 00:41:28,060
Then that is a mismatch, right?

909
00:41:28,060 --> 00:41:31,420
What you are expecting by pass a validator,

910
00:41:31,420 --> 00:41:32,740
the login should be successful.

911
00:41:32,740 --> 00:41:35,700
When I pass invalidator, login should not be successful.

912
00:41:35,700 --> 00:41:37,300
That is your expectation.

913
00:41:37,300 --> 00:41:39,660
But how actually application is working?

914
00:41:39,660 --> 00:41:43,460
If I pass validator, okay, it is successfully login.

915
00:41:43,460 --> 00:41:45,660
But even if you pass invalidator,

916
00:41:45,660 --> 00:41:47,540
still it is accepting the login.

917
00:41:47,540 --> 00:41:49,380
So that is a mismatch.

918
00:41:49,380 --> 00:41:53,500
What is our expectation and how the application is working?

919
00:41:53,500 --> 00:41:55,740
So the deviation from expected behavior

920
00:41:55,740 --> 00:41:58,540
and actual behavior is basically called as a bug,

921
00:41:59,420 --> 00:42:01,940
and which is also called as a defect.

922
00:42:01,940 --> 00:42:03,580
The terminologies are different guys.

923
00:42:03,580 --> 00:42:06,260
The concept is same, okay?

924
00:42:06,260 --> 00:42:09,340
So error is a human mistake.

925
00:42:09,340 --> 00:42:11,540
Bug and defect is something different.

926
00:42:11,540 --> 00:42:13,460
So this is related to application.

927
00:42:13,460 --> 00:42:16,100
Something is not working in our application

928
00:42:16,100 --> 00:42:19,820
according to your expectation or your requirement

929
00:42:19,820 --> 00:42:21,420
or customer requirement,

930
00:42:21,420 --> 00:42:26,220
which is basically called as a bug or defect, okay?

931
00:42:26,220 --> 00:42:28,100
And the third thing is a failure.

932
00:42:28,100 --> 00:42:29,620
What is failure?

933
00:42:29,620 --> 00:42:31,620
Suppose we develop some software,

934
00:42:31,620 --> 00:42:34,620
we have tested and everything is working fine.

935
00:42:34,620 --> 00:42:35,740
And finally, what you will do?

936
00:42:35,740 --> 00:42:38,220
We will deliver the software to the customer.

937
00:42:38,220 --> 00:42:39,580
And we have installed the software

938
00:42:39,580 --> 00:42:41,260
in the customer environment,

939
00:42:41,260 --> 00:42:43,740
and they started using the software.

940
00:42:43,740 --> 00:42:46,740
And after a few days, then what happens?

941
00:42:46,740 --> 00:42:51,740
There is something which is not working in the software, okay?

942
00:42:51,940 --> 00:42:54,740
And something basically got failed, okay?

943
00:42:54,740 --> 00:42:56,820
So whatever the customer wanted to do,

944
00:42:56,820 --> 00:42:58,820
some transaction that is got failed.

945
00:42:59,780 --> 00:43:03,620
So this is basically end user action, okay?

946
00:43:03,620 --> 00:43:06,860
So the deviation identified by end user

947
00:43:06,860 --> 00:43:08,900
while using the software,

948
00:43:08,900 --> 00:43:11,540
the deviation identified by the end user

949
00:43:12,780 --> 00:43:16,260
while working with the software is called as a failure.

950
00:43:16,260 --> 00:43:21,060
Again, I'm repeating, error is a human mistake, okay?

951
00:43:21,060 --> 00:43:22,540
While writing the program,

952
00:43:22,540 --> 00:43:25,620
developer will do a lot of mistakes.

953
00:43:25,620 --> 00:43:27,460
All these comes under the errors.

954
00:43:28,500 --> 00:43:30,900
And while testing the software,

955
00:43:30,900 --> 00:43:33,380
we are checking the functionality of our application,

956
00:43:34,140 --> 00:43:34,980
whether it is working according

957
00:43:34,980 --> 00:43:36,860
to customer requirement or not.

958
00:43:36,860 --> 00:43:38,300
If something is not working

959
00:43:38,300 --> 00:43:39,860
according to customer requirement,

960
00:43:39,860 --> 00:43:42,220
which is comes under the bug or defect.

961
00:43:43,300 --> 00:43:45,660
And after releasing the product to the customer

962
00:43:45,660 --> 00:43:47,300
and the customer is using the software,

963
00:43:47,300 --> 00:43:50,380
or as a user, I'm working with the software

964
00:43:50,380 --> 00:43:51,980
in the real environment,

965
00:43:51,980 --> 00:43:53,420
where I found some bugs,

966
00:43:53,420 --> 00:43:54,700
where I found some mismatch,

967
00:43:54,700 --> 00:43:57,100
where I found something is not working,

968
00:43:57,100 --> 00:43:59,340
that is comes under the failure.

969
00:43:59,340 --> 00:44:02,660
And the error normally committed by the developers,

970
00:44:02,660 --> 00:44:05,940
bugs and defects will be identified by the testers

971
00:44:05,940 --> 00:44:08,300
at the time of testing phase.

972
00:44:08,300 --> 00:44:11,460
And failures will be there in the production environment.

973
00:44:11,460 --> 00:44:14,820
Production means in the sense, customer environment.

974
00:44:14,820 --> 00:44:17,380
And where if the customer is identified something

975
00:44:17,380 --> 00:44:18,780
or which is not working properly,

976
00:44:18,780 --> 00:44:21,700
that we can call it as a failure, okay?

977
00:44:21,700 --> 00:44:24,060
So the basic difference between error,

978
00:44:24,060 --> 00:44:27,620
bug or defect or failure.

979
00:44:27,620 --> 00:44:29,740
Okay, just understand these technologies,

980
00:44:29,740 --> 00:44:32,380
which is very, very important, okay?

981
00:44:32,380 --> 00:44:34,100
So most frequently I use these terms,

982
00:44:34,100 --> 00:44:36,940
a bug or defect, both are same,

983
00:44:36,940 --> 00:44:41,940
but error is a different, failure is a different, okay?

984
00:44:42,060 --> 00:44:43,780
So these are some basics guys.

985
00:44:43,780 --> 00:44:46,540
So why the software has bugs?

986
00:44:46,540 --> 00:44:48,500
Let me discuss one more point.

987
00:44:48,500 --> 00:44:49,900
So why the software has bugs?

988
00:44:49,900 --> 00:44:53,220
So far we are discussing like why, what is software?

989
00:44:53,220 --> 00:44:54,700
What is software testing?

990
00:44:54,700 --> 00:44:57,740
And why we need to conduct the testing, right?

991
00:44:57,740 --> 00:44:59,700
But why the software has bugs?

992
00:44:59,700 --> 00:45:01,540
So when I develop some software,

993
00:45:01,940 --> 00:45:04,980
it contains some bugs, but why we should have bugs?

994
00:45:04,980 --> 00:45:07,020
There are a lot of reasons out there.

995
00:45:07,020 --> 00:45:08,620
Why the software is having bugs?

996
00:45:08,620 --> 00:45:10,260
There are a lot of reasons.

997
00:45:10,260 --> 00:45:12,540
The mainly five reasons guys.

998
00:45:12,540 --> 00:45:14,620
The mainly three, five reasons we can say.

999
00:45:16,260 --> 00:45:21,140
Why the software has bugs?

1000
00:45:22,460 --> 00:45:23,700
So why the software has bugs?

1001
00:45:23,700 --> 00:45:25,460
So mainly five reasons.

1002
00:45:25,460 --> 00:45:30,460
The first reason is miscommunication or no communication.

1003
00:45:31,580 --> 00:45:33,140
Means what?

1004
00:45:33,140 --> 00:45:35,100
There is no proper communication

1005
00:45:35,100 --> 00:45:38,100
between the developers and testers.

1006
00:45:38,100 --> 00:45:39,020
Means what?

1007
00:45:39,020 --> 00:45:41,180
Developer will develop something

1008
00:45:41,180 --> 00:45:44,180
and tester will expecting something else.

1009
00:45:44,180 --> 00:45:46,940
Or requirement is having some functionality

1010
00:45:46,940 --> 00:45:49,780
and developer is implemented or develop some other things,

1011
00:45:49,780 --> 00:45:53,300
some other functionality and tester is expecting something.

1012
00:45:53,300 --> 00:45:57,180
So there will be gap between the documentation,

1013
00:45:57,180 --> 00:45:59,140
development and testing.

1014
00:45:59,140 --> 00:46:02,020
So that is basically comes on the miscommunication

1015
00:46:02,020 --> 00:46:03,700
or no communication.

1016
00:46:03,700 --> 00:46:06,500
So that is causing the software bugs.

1017
00:46:06,500 --> 00:46:09,380
So the requirement should be very, very clear.

1018
00:46:09,380 --> 00:46:12,340
And according to the developer should develop the software.

1019
00:46:12,340 --> 00:46:15,060
And according to the tester also should test the software.

1020
00:46:15,060 --> 00:46:17,660
Everybody should be in the proper sync.

1021
00:46:17,660 --> 00:46:20,700
And then only we can deliver the quality product

1022
00:46:20,700 --> 00:46:21,860
to the customer.

1023
00:46:21,860 --> 00:46:23,380
If there is any miscommunication,

1024
00:46:23,380 --> 00:46:25,980
suppose developer is develop something

1025
00:46:26,020 --> 00:46:29,380
and which is not communicated with the testing team.

1026
00:46:29,380 --> 00:46:30,220
Then what happens?

1027
00:46:30,220 --> 00:46:32,140
Tester will think in different way

1028
00:46:32,140 --> 00:46:34,420
and they do their testing their own way.

1029
00:46:34,420 --> 00:46:37,540
And tester also needs some developer's input.

1030
00:46:37,540 --> 00:46:40,540
Even developer also needs some input from the testing.

1031
00:46:42,100 --> 00:46:45,820
So everybody in the team should communicate properly

1032
00:46:45,820 --> 00:46:50,420
and that can avoid the bugs in our software.

1033
00:46:50,420 --> 00:46:52,860
That is one major reason.

1034
00:46:52,860 --> 00:46:55,860
And the second reason is the complexity of the software.

1035
00:46:55,860 --> 00:46:58,300
Suppose the software is very complex.

1036
00:46:58,300 --> 00:47:00,820
It is almost three, four, five years project.

1037
00:47:00,820 --> 00:47:03,980
And so many people are working like N number of developers,

1038
00:47:03,980 --> 00:47:06,740
N number of testers, automation people,

1039
00:47:06,740 --> 00:47:08,180
so much complexities.

1040
00:47:08,180 --> 00:47:11,780
And N number of modules are there, sub-modules are there.

1041
00:47:11,780 --> 00:47:14,860
In that case also we can miss some bugs, okay?

1042
00:47:14,860 --> 00:47:16,700
Like integration testing, unit testing.

1043
00:47:16,700 --> 00:47:18,780
There are lot of testings we will conduct.

1044
00:47:18,780 --> 00:47:21,740
And somewhere we may miss something else.

1045
00:47:21,740 --> 00:47:25,300
So that is again causing the bugs in later stages.

1046
00:47:25,300 --> 00:47:27,660
So suppose in some cases in sometimes

1047
00:47:27,660 --> 00:47:30,100
even if the software is very complex,

1048
00:47:30,100 --> 00:47:34,540
there are some chances we have some bugs in our software.

1049
00:47:34,540 --> 00:47:37,580
And the third reason is programming errors.

1050
00:47:37,580 --> 00:47:39,740
And most of the times programming errors

1051
00:47:39,740 --> 00:47:42,700
in the sense it is a responsibility of the developers.

1052
00:47:42,700 --> 00:47:45,260
So developers will write the program,

1053
00:47:45,260 --> 00:47:47,420
but the program is working fine.

1054
00:47:47,420 --> 00:47:50,020
But whatever output is producing is not correct.

1055
00:47:50,940 --> 00:47:52,820
That comes out of the programming error.

1056
00:47:52,820 --> 00:47:55,460
So for example, developer has written a program

1057
00:47:55,460 --> 00:47:56,460
to add two numbers.

1058
00:47:56,460 --> 00:47:59,220
Let us say some example, what is programming error?

1059
00:47:59,220 --> 00:48:02,780
So developer is written some programming, some program.

1060
00:48:02,780 --> 00:48:04,260
And when I pass two inputs,

1061
00:48:04,260 --> 00:48:05,740
let's say I have passed the two numbers,

1062
00:48:05,740 --> 00:48:07,940
let's say two comma three.

1063
00:48:07,940 --> 00:48:09,780
And what is the output I'm expecting?

1064
00:48:09,780 --> 00:48:12,780
Two plus three, five I'm expecting, okay?

1065
00:48:12,780 --> 00:48:15,820
And this way the program is written the code.

1066
00:48:15,820 --> 00:48:18,860
But when I run the program, what happens?

1067
00:48:18,860 --> 00:48:22,100
When I pass this input, which is giving the output,

1068
00:48:22,100 --> 00:48:23,380
but something else,

1069
00:48:23,380 --> 00:48:25,820
let us say it is giving something called 10,

1070
00:48:25,820 --> 00:48:28,060
the program is running perfectly fine.

1071
00:48:28,060 --> 00:48:29,820
But whatever the output I'm getting

1072
00:48:29,820 --> 00:48:32,020
from the program is incorrect.

1073
00:48:32,020 --> 00:48:33,860
So why this is gone?

1074
00:48:33,860 --> 00:48:35,500
Why we are getting this incorrect error

1075
00:48:35,500 --> 00:48:37,820
because of programming error.

1076
00:48:37,820 --> 00:48:42,500
So the developers will take care of this programming errors.

1077
00:48:42,500 --> 00:48:44,540
Okay, so that is one thing.

1078
00:48:44,540 --> 00:48:48,020
And the next one is a frequently changing requirements.

1079
00:48:48,020 --> 00:48:50,660
This is a major cause.

1080
00:48:50,660 --> 00:48:52,700
So sometimes what happens is,

1081
00:48:52,700 --> 00:48:54,620
like initially the customer will give you

1082
00:48:54,620 --> 00:48:57,180
a few number of requirements, okay?

1083
00:48:57,180 --> 00:48:58,900
And okay, we have started,

1084
00:48:58,900 --> 00:49:00,380
we have understood all the requirement,

1085
00:49:00,380 --> 00:49:02,580
we have started development.

1086
00:49:02,580 --> 00:49:04,660
And in the middle of the development,

1087
00:49:04,660 --> 00:49:09,660
sometime again customer come back and change their requirement.

1088
00:49:09,820 --> 00:49:12,420
But initially they said something after some time

1089
00:49:12,420 --> 00:49:14,900
after developing or during the testing phase,

1090
00:49:14,900 --> 00:49:18,540
they'll come back and ask us to change some requirement.

1091
00:49:18,540 --> 00:49:21,100
And that is also causing the bugs.

1092
00:49:21,100 --> 00:49:22,620
And sometimes it may possible

1093
00:49:22,620 --> 00:49:25,740
or it may not be possible to change the application

1094
00:49:25,740 --> 00:49:27,380
according to their requirement.

1095
00:49:27,380 --> 00:49:30,820
So even if a customer requirements are frequently changing,

1096
00:49:30,820 --> 00:49:34,660
that is also sometimes causing the bugs.

1097
00:49:34,660 --> 00:49:37,740
And the last reason, lack of skilled testers.

1098
00:49:37,740 --> 00:49:40,900
If the tester doesn't have proper skill set,

1099
00:49:40,900 --> 00:49:43,980
definitely he will miss the bugs.

1100
00:49:43,980 --> 00:49:46,740
So if the tester is not identified the bugs,

1101
00:49:46,740 --> 00:49:48,000
then what happens?

1102
00:49:48,000 --> 00:49:50,200
That will go to the next level

1103
00:49:50,200 --> 00:49:52,420
and that will come again in the production.

1104
00:49:52,420 --> 00:49:55,740
The customer will face that bug, okay?

1105
00:49:55,740 --> 00:49:57,060
So that is a problem.

1106
00:49:57,060 --> 00:50:00,460
So the tester should have proper skill set.

1107
00:50:00,460 --> 00:50:02,600
That is very, very important.

1108
00:50:02,600 --> 00:50:05,540
And a tester should have a different mindset guys.

1109
00:50:05,540 --> 00:50:06,700
So especially for tester,

1110
00:50:06,700 --> 00:50:09,560
we need to always think about in the negative way.

1111
00:50:09,560 --> 00:50:11,620
So normally people are saying positive way,

1112
00:50:11,620 --> 00:50:14,220
we need to think, but here in the testing point of view,

1113
00:50:14,220 --> 00:50:16,220
always we have to think like,

1114
00:50:16,220 --> 00:50:17,580
we have to break the application.

1115
00:50:17,580 --> 00:50:19,420
Somewhere we need to find the application.

1116
00:50:19,420 --> 00:50:20,860
If you want to find the application,

1117
00:50:20,860 --> 00:50:22,740
if you want to find some bug,

1118
00:50:22,740 --> 00:50:23,580
then what you have to do,

1119
00:50:23,580 --> 00:50:26,060
we have to provide some invalid data.

1120
00:50:26,060 --> 00:50:28,420
Okay, we have to do some unwanted stuff in our application.

1121
00:50:28,420 --> 00:50:32,540
So then whether we are providing some data to the application,

1122
00:50:32,540 --> 00:50:33,900
how it is behaving,

1123
00:50:33,900 --> 00:50:35,420
whether it is behaving according

1124
00:50:35,420 --> 00:50:37,500
to customer requirement or not.

1125
00:50:37,500 --> 00:50:38,700
So that we need to test.

1126
00:50:38,700 --> 00:50:41,680
Always our focus should be on breaking the application.

1127
00:50:42,660 --> 00:50:44,520
Okay, so if everything is working fine,

1128
00:50:44,520 --> 00:50:46,400
there is no job for tester.

1129
00:50:46,400 --> 00:50:50,360
We have to break our application with our skill set.

1130
00:50:50,360 --> 00:50:53,120
So that is exactly software tester job.

1131
00:50:53,120 --> 00:50:57,120
Okay, so for that, we need to have proper skill set.

1132
00:50:57,120 --> 00:50:58,160
Very, very important.

1133
00:50:59,100 --> 00:51:01,560
Okay, so why is the software having bugs?

1134
00:51:01,560 --> 00:51:04,460
Mixed communication or new communication?

1135
00:51:04,460 --> 00:51:07,040
And because of software complexity

1136
00:51:07,040 --> 00:51:10,140
and sometimes programming errors also causing the bugs.

1137
00:51:10,140 --> 00:51:13,380
And if the requirements also keep on changing very frequently,

1138
00:51:13,380 --> 00:51:15,260
that is also causing the bugs.

1139
00:51:15,260 --> 00:51:18,500
And finally, lack of skilled testers.

1140
00:51:18,500 --> 00:51:21,340
If the testers doesn't have proper skills,

1141
00:51:21,340 --> 00:51:24,020
then definitely he will miss the bugs.

1142
00:51:24,020 --> 00:51:26,980
And those bugs will be faced by the customers.

1143
00:51:26,980 --> 00:51:30,020
And he will start frustrating by seeing those bugs

1144
00:51:30,020 --> 00:51:32,100
in the production environment.

1145
00:51:32,100 --> 00:51:35,980
Okay, so these are all very, very important things

1146
00:51:35,980 --> 00:51:37,640
before starting the testing.

1147
00:51:38,520 --> 00:51:43,440
And then we have something called SDLC, SDLC and so on.

1148
00:51:43,440 --> 00:51:46,360
So we will discuss these things in the next session.

1149
00:51:46,360 --> 00:51:48,240
Okay, so these are the basics guys.

1150
00:51:48,240 --> 00:51:50,360
Like we have understood what is software,

1151
00:51:50,360 --> 00:51:53,280
types of softwares and what is software testing,

1152
00:51:53,280 --> 00:51:55,160
what is software quality,

1153
00:51:55,160 --> 00:51:58,200
and what are the parameters of software quality

1154
00:51:58,200 --> 00:52:00,040
and project and product.

1155
00:52:00,040 --> 00:52:02,420
And why do we need software testing?

1156
00:52:02,420 --> 00:52:03,880
And we also understood the difference

1157
00:52:03,880 --> 00:52:06,920
between error, bug and failure.

1158
00:52:06,920 --> 00:52:11,360
And finally, we have understood why the software has bugs.

1159
00:52:11,360 --> 00:52:13,360
Okay, so in the next session,

1160
00:52:13,360 --> 00:52:16,120
we are going to discuss the rest of the topics.

1161
00:52:16,120 --> 00:52:18,640
And I'm just stopping here for today, guys.

1162
00:52:18,640 --> 00:52:20,380
Now, if you have any queries,

1163
00:52:20,380 --> 00:52:22,920
you guys can post in your chat window

1164
00:52:22,920 --> 00:52:24,960
or you guys can ask me.

1165
00:52:24,960 --> 00:52:26,800
Okay, and the rest of the things

1166
00:52:26,800 --> 00:52:28,720
will continue on tomorrow's session.

1167
00:52:30,240 --> 00:52:31,320
Just a moment.
