What is a test case?

• A. A comprehensive report of system performance
• B. A defined set of conditions and inputs for evaluation
• C. A checklist for system features to be tested
• D. A summary of previous testing results

Answer: (B)

A test case is fundamentally a defined set of conditions and inputs that are used to evaluate a specific function, feature, or performance aspect of a system. It outlines the steps to be executed, the inputs to be used, and the expected outcomes, which helps in determining whether the system behaves as intended under the specified scenarios. This structured approach allows testers to systematically verify the functionality and reliability of the system. By establishing clear conditions and inputs, a test case can guide the testing process, ensuring that key aspects of the system are evaluated comprehensively and accurately. The use of test cases is critical in the testing and validation phases, as they lead to more reliable and repeatable test results. In contrast, while the other options reflect different aspects of testing and evaluation, they do not encapsulate the purpose and structure of a test case as effectively. For instance, a comprehensive report of system performance encapsulates results rather than the conditions for testing, and a checklist for system features focuses on verification rather than detailed evaluation of specific functionalities. A summary of previous testing results pertains to historical data rather than setting up conditions for new tests, which does not align with the concept of a test case.
