When performing requirements-based testing, what is primarily utilized?

In requirements-based testing, the primary focus is to ensure that the software meets the specific requirements it was designed to fulfill. This involves identifying test objectives and conditions that are directly derived from the documented requirements of the project. By utilizing these requirements as the foundation for test cases, testers can systematically validate whether the application behaves as intended and satisfies the needs of stakeholders.

This approach emphasizes alignment with business goals and user expectations, making it an effective strategy for confirming that each requirement has been addressed in the development process. Consequently, the clarity and specificity of the requirements become crucial, as they guide the development of test scenarios that reflect what the software should accomplish.

Other options, while relevant in various contexts of testing and project management, do not serve as the primary focus in requirements-based testing. For instance, defects from previous versions can inform testing but do not directly reflect current requirements. Similarly, feedback from user acceptance tests and historical project metrics provide insights but are not specific to the requirements basis for creating test cases.
