Test coverage gaps occur when critical code paths lack real assertions or contain stub files. Audit your test inventory to identify untested paths, empty test files, and areas missing executable specifications that validate actual behavior.

Stub tests contain placeholder code without meaningful assertions; executable tests run real assertions against actual behavior. Real tests verify concrete outcomes and catch regressions, while stubs create false confidence in coverage metrics.

Prioritize critical paths—core business logic and error handling—before peripheral features. Build a gap analysis identifying untested critical paths, then enforce quality gates ensuring each new test contains non-empty assertions targeting real behavior.

Yes. Enforce maintainable test structures with explicit quality gates that require passing tests, meaningful assertions, and coverage of critical paths. This ensures your test suite remains executable and reliable across updates.

High coverage metrics can mask stub files and empty tests that don't validate real behavior. True coverage requires executable tests with assertions that actually run—turning specifications into verifiable, maintainable code.

Establish readable test structures with explicit quality gates and enforce standards preventing stub files. Regular audits identify gaps in critical paths, ensuring new tests target real behavior and remain maintainable under continuous development.
