What does a test plan describe?

A test plan serves as a fundamental document in the software testing process, outlining the overall strategy for testing. It details the scope of the testing, describing what will and will not be tested, and addresses the approach or methodology that will be used during the testing phase. Additionally, the test plan specifies the resources needed for testing—this may include personnel, tools, and environments—and provides a schedule indicating when various testing activities will take place.

This comprehensive overview enables all stakeholders to have a clear understanding of how testing will be conducted, the objectives of the tests, and the timelines involved. By clearly defining these elements, the test plan helps ensure that the testing process is organized and aligned with project goals, ultimately contributing to the successful delivery of a quality product.
