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

The master test plan is a comprehensive document that outlines the overall testing strategy and planning for a project. It serves as a blueprint for the entire testing effort and should detail key aspects that will guide the testing process.

Focusing on regression testing in the master test plan is essential because it encompasses how testing will be conducted after changes or modifications to the codebase. Regression testing ensures that new code changes do not adversely affect the existing functionality of the software. Detailing an approach to regression testing helps stakeholders understand how the integrity of the software will be maintained throughout its development lifecycle, ensuring that previously working features remain functional after new updates.

In contrast, while a list of test data, test point allocation, and a collection of user stories are important elements in the testing process, they do not provide the broad strategic overview that the master test plan aims to convey. Test data is typically more operational and would be managed at a lower level, while test point allocation focuses on assigning specific test cases. User stories represent requirements but do not directly relate to the overarching testing strategies that the master test plan should contain.
