Ideally, UAT testing should provide the opportunity to uncover any remaining bugs, and to test usability directly in the operational environment. These tests should generate a confident certainty that the software will function as designed when it goes live. However, this isn't always the case.
All successful applications have certain traits in common. They are easy to configure, they have intuitive interfaces that are easy to learn and they are friendly to operating systems and other software. Most importantly, they smoothly fulfill user requirements. The key to fulfilling those requirements is a well planned, well administered development cycle.
User Acceptance testing is the final stage in quality assurance and quality is no longer simply, “Does it work?” Usability has become a part of functionality. While function and regression tests validate functional specifications, User Acceptance Testing validates both the quality of the interface and the suitability of the application for its intended purpose.
There are several important distinctions between Bugwolf's gamified approach to manual exploratory testing and most conventional "crowdsourced" approaches...
User Acceptance Testing (UAT) has grown out of the Agile Testing framework and has become more important as the importance of the user has increased. The basis of Agile Testing is using self-organizing and cross functioning teams that can evolve solutions through adaptive planning and method evolution.
User acceptance testing was traditionally carried out just before the software went live. This has changed. Modular testing has now spread UAT throughout the development cycle. However, the purpose of UAT remains the same, although the spreading of user acceptance testing across development has increased the challenges faced by testers.
