Which method ensures that tests are actually validating the code?
Show answer Hide answer
Answer: C. Code coverage
Explanation
Code coverage measures the percentage of source code executed by test cases to validate logic. High coverage guarantees that test suites exercise critical paths and catch hidden programming errors. Tracking executed statements confirms that tests actually validate the underlying code implementation. Test coverage metrics analyze how thoroughly automated test suites execute source code statements. Statement, branch, and path coverage represent common measures used by testing tool suites. Low coverage percentages reveal untested code regions that may harbor latent defects.
Development teams set minimum code coverage thresholds as a prerequisite for merging pull requests. Analyzing coverage reports helps testers write targeted unit tests for overlooked conditional branches. Ensuring high code coverage improves overall software reliability and reduces production bug rates. Control structure testing designs test cases based on the logical flow of program control paths. Complex path testing focuses on executing intricate nested loops and conditional branch combinations. Quality assurance of software is a broad management discipline rather than a specific test validation method.
