Which of the following defines the scope and limits of a test process?

The concept that defines the scope and limits of a test process is the test plan. A test plan outlines the objectives, resources, schedule, and specific activities that will be carried out during testing. It identifies the boundaries of the testing effort, specifying what will be tested and what will not, often referred to as the "in-scope" and "out-of-scope" items. By doing so, it ensures that all stakeholders have a clear understanding of the focus of the testing activities, thus helping manage expectations and resource allocation effectively.

In contrast, a test strategy provides a higher-level overview of the testing approach and how testing aligns with the business goals, but it does not delve into specific details about how each test will be executed. A test environment refers to the setup required to conduct tests, including hardware, software, and network configurations, and does not define the testing scope. Test design involves the process of identifying and specifying the test cases based on requirements and designs but does not define the overall parameters and limitations of the test process itself.
