At what stage in the UAT lifecycle are successful and failed tests reported?

The stage in the User Acceptance Testing (UAT) lifecycle where successful and failed tests are reported is during test execution. This phase involves the actual running of test cases that have been designed previously. During this stage, testers will take the developed test scripts and execute them against the actual software.

As testers execute the tests, they document the outcomes, which include noting whether a test passed or failed based on the predefined acceptance criteria. This reporting is crucial because it provides immediate feedback regarding the functionality and performance of the application, allowing stakeholders to assess whether the software meets user requirements.

In contrast, the other stages focus on different aspects of the UAT process. Defect management involves logging, categorizing, and addressing any issues found during testing but does not focus on the execution phase itself. Test design is concerned with creating the test cases prior to execution, and test strategy outlines the overall plan and approach for testing but does not involve the actual reporting of results. Therefore, the execution phase is the critical stage for reporting on test outcomes.
