What does "test coverage" refer to in evaluation?

• A. Frequency of test executions
• B. Extent to which tests address defined requirements
• C. The number of tests conducted
• D. Budget allocated for testing

Answer: (B)

Test coverage specifically refers to the extent to which tests address defined requirements. This concept is critical in evaluation as it helps to determine how comprehensively the testing process validates that a system or product meets its specifications and requirements. A high level of test coverage ensures that various aspects of the system are examined, reducing the likelihood of undiscovered defects and increasing confidence in the product’s reliability and performance.

In test planning, establishing adequate coverage allows testers to identify gaps where requirements may not have been adequately validated through testing. Thus, it significantly impacts the overall quality assurance process.

The other options do not capture the essence of what test coverage means. For instance, the frequency of test executions pertains more to the testing schedule rather than ensuring all requirements are adequately tested. The number of tests conducted provides a quantitative measure but does not necessarily reflect whether all requirements are being met. Lastly, the budget allocated for testing relates to resource considerations and does not directly pertain to how thoroughly the requirements are addressed within the tests performed.
