Functional User Acceptance Testing

User Acceptance Testing (UAT) is a type of testing performed by the end user or the client to verify/accept the software system before moving the software application to the production environment. UAT is done in the final phase of testing after functional, integration and system testing is done. The main Purpose of UAT is to validate end to end business flow. It does not focus on cosmetic errors, spelling mistakes or system testing. User Acceptance Testing is carried out in a separate testing environment with production-like data setup. It is kind of black box testing where two or more end-users will be involved. Need of User Acceptance Testing arises once software has undergone Unit, Integration and System testing because developers might have built software based on requirements document by their own understanding and further required changes during development may not be effectively communicated to them, so for testing whether the final product is accepted by client/end-user, user acceptance testing is needed.

A user acceptance test is the final stop in the software testing process and one of the most important stages. It helps ensure that the system is intuitive enough for a user to navigate it effortlessly, it meets the audience’s expectations, and caters to its needs. Missing out on proper UAT planning creates panic within the team when the application is about to be brought to the market. The testing process should be well-strategist and completed in advance so that the development team can fix errors and performance issues before the product’s final release ,such as:
