hello and welcome to this episode of ask Raghav In QA and in Testing in general we do functional testing where we check our application meets all the functional requirements, but what if a person with some special needs have to use our application there may be a person with some visual impairment or there maybe a blind user there may be a person with some auditory or hearing issues or maybe some cognitive issues now accessibility testing is all about making sure that people with some special needs can use our application that we can use and make sure that our application is accessible to everyone, it is a non-functional testing and here we can use tools like speech recognition software, so for example there can be a person with some visual issues or impairment, so in that case there must be some speech recognition software that the person can just speak, and the software should be able to understand and take the command from the user.
