What document defines the tests to be executed for end user testing after the development phase?

The document that specifically outlines the tests to be executed for end user testing after the development phase is the UAT (User Acceptance Testing) plan. This plan serves as a crucial roadmap for validating whether the developed software meets the business requirements and is acceptable for end users.

The UAT plan typically includes detailed information on test cases, the criteria for acceptance, the intended scope of testing, and the responsibilities of the end users involved in the testing process. It ensures that all necessary scenarios are covered, allowing users to verify that the system performs as expected in real-world situations.

In contrast, the other options do not focus on this aspect of testing. The process definition document details the workflows and processes to be automated, serving to outline what needs to be automated rather than how it will be tested. The application tracker is generally used for monitoring progress and issues within an application but does not define test cases. Meanwhile, the solution design document describes the technical aspects of the solution being developed, including architecture and components, rather than the specific tests for user acceptance. Thus, the UAT plan is essential for guiding end users on what tests need to be executed and ensuring thorough validation of the system before it goes live.
