What is the activity of establishing or updating a test plan known as?

The activity of establishing or updating a test plan is known as test planning. This process involves defining the scope and objectives of testing, determining the resources required, developing a schedule, and identifying the risks associated with the testing process.

Test planning is crucial as it provides a structured approach to how testing will be conducted, ensuring that all necessary aspects are considered before the actual testing begins. A well-prepared test plan serves as a roadmap for the testing team, guiding them through the execution of test cases, managing resources, and communicating expectations to stakeholders.

In contrast, test control refers to the ongoing monitoring and adjustment of the test process to ensure that it stays on track, while test design involves the creation of test cases and test scripts based on the requirements and specifications. Test execution is the process of running the tests and capturing the results. Each of these activities is vital, but they occur at different stages in the testing process, establishing the distinct role that test planning plays in ensuring the overall quality and success of the testing effort.
