How does test case definition benefit the testing process?

• A. Provides a random sampling of system features
• B. Establishes clear criteria for system evaluation
• C. Increases the overall test duration
• D. Affects the visual design of the system

Answer: (B)

Defining test cases is a fundamental aspect of the testing process because it establishes clear criteria for evaluating the system. By having well-defined test cases, testers can ensure that they are measuring specific functionalities and performance criteria against predetermined benchmarks. This clarity helps eliminate ambiguity in what is being tested and allows for consistent results across different test executions.

Furthermore, clear definitions empower teams to perform systematic and focused testing, enhancing the reliability of test outcomes. It also facilitates easier identification of defects or issues by providing a structured approach to follow, which can be referenced later for validation and regression testing. A well-defined basis for evaluation is essential in ensuring that the system meets its requirements and functions as intended.

The other options do not accurately support the benefits of test case definition in the same way. Random sampling might overlook critical features, increasing test duration and affecting visual design are not benefits and could lead to inefficiencies in the testing process.
