What is meant by "test coverage"?

• A. The extent to which testing addresses all aspects of a system's functionality
• B. The total time taken for the testing process
• C. The number of testers involved in the process
• D. The completeness of the test documentation

Answer: (A)

Test coverage refers to the extent to which testing addresses all aspects of a system's functionality. This concept is crucial in evaluating the thoroughness of the testing process. High test coverage means that more features, requirements, or paths within a system have been verified through testing, which can lead to a higher confidence level in the system's reliability and performance. In the context of software testing, it often encompasses various areas such as functional coverage, where different functionalities are tested; code coverage, which measures the percentage of code executed during tests; and requirement coverage, ensuring test cases are aligned with specified requirements. By achieving comprehensive test coverage, testers can identify defects earlier and validate that the system behaves as expected under different conditions. This is essential in ensuring product quality and minimizing the risk of failures in the operational environment, especially for complex systems where missing a critical functionality could lead to significant issues. Other options, while they may relate to aspects of testing, do not encapsulate the core idea of what test coverage represents. The total time taken for the testing process and the number of testers involved provide insights into testing efficiency and resources, but they do not define the scope of testing concerning the functionalities being assessed. Similarly, the completeness of test documentation is important for traceability and understanding
