What should be addressed in detail in the master test plan?

The master test plan serves as a comprehensive document that outlines the testing strategy for a project. It is essential for guiding the testing efforts and ensuring that all necessary elements are covered for successful execution.

The inclusion of an approach to regression testing in the master test plan is crucial because regression testing is a key aspect of software testing. It verifies that recent changes to the code (such as bug fixes or new features) do not adversely affect the existing functionality of the software. By detailing the regression testing approach, the master test plan ensures that the team is aligned on how to execute these tests, what types of tests will be conducted, the environment settings, and any specific tools or frameworks that will be utilized. This structured approach helps in identifying risks associated with new changes and ensures that the quality of the software product remains intact over time.

In contrast, while the other options might be relevant to the overall testing context, they do not encompass the high-level strategy and planning required in the master test plan as thoroughly as a regression testing strategy does. For example, a list of test data is more operational than strategic, test point allocation might refer to task assignment rather than strategy, and user stories pertain more to the functional requirements rather than the testing approach itself.
