User acceptance testing

User Acceptance testing is performed considering the users environment or production environment. Test suite is prepared to be executed for user acceptance testing. User acceptance testing is performed when the system is ready for release. It is usually performed by the client or the end user as a confirmation to accept the system. All the different types of testing are completed before the user acceptance testing is done. It is a type of black box testing because the end user is usually unaware of the internal working of the system. User acceptance testing plays an extremely important role because it helps to identity the user’s perspective. If the user acceptance testing is successful, it signifies the completion of the application and introduces a sense of confidence to use the system.
