Code Coverage

Developers should use code coverage to ensure comprehensive testing, especially in critical applications like financial systems, healthcare software, or safety-critical systems where reliability is paramount

Pros

• It helps prioritize test writing for uncovered code, supports refactoring by verifying existing functionality, and is often required in CI/CD pipelines to enforce quality gates before deployment
• Related to: unit-testing, integration-testing

Cons

• Specific tradeoffs depend on your use case
