Which of the following is not decided in the test-planning phase?

In the test-planning phase, various critical aspects of the testing process are established to ensure that the testing is organized, efficient, and aligned with the overall project goals. One of the key activities in this phase is defining schedules and deliverables, which outlines the timeline for testing activities and what is expected to be delivered at the end of the testing process. Additionally, decisions surrounding hardware and software requirements, as well as entry and exit criteria, are essential to define what is necessary to start testing and when testing can be deemed complete.

However, the specific types of test cases typically are not concretely defined during the planning phase. Rather, these are determined later during the test design phase, where testers identify the actual test cases based on the requirements and the detailed understanding of the system. Test cases are designed considering factors such as the application's functional specifications, usability, performance requirements, and risk assessments, which require more detailed information than is typically available in the initial planning stages. Thus, while planning and strategy are a part of the planning phase, the specifics about the types of test cases to be executed are addressed later in the testing lifecycle.
