Test adequacy is verified by analyzing code diffs to identify missing regression coverage, ensuring bug fixes are pinned by tests that would have failed prior to the fix. It evaluates branch coverage and validates that new logic branches are explicitly tested.

Superficial test coverage often stems from weak assertions and brittle test patterns. Evaluating test effectiveness against production diffs identifies missing branch coverage, mock boundary integrity issues, and nondeterministic flake triggers that mask real interface changes.

Mock boundary integrity is analyzed during code review to identify brittle mocks that mask real interface changes. The evaluation checks if tests properly validate public API contract changes and new logic branches rather than relying on shallow mock implementations.

Nondeterministic flake triggers are detected by analyzing test patterns for improper async handling and shared state. The review process validates that test suites provide meaningful failure signals rather than passing inconsistently due to hidden state dependencies.

Automated test review validates branch and contract coverage by evaluating the effectiveness of new tests against production diffs. It explicitly checks that new logic branches and public API changes are covered, ensuring meaningful failure signals for feature implementations.

You should audit tests when adding bug fixes or new features to ensure they provide meaningful failure signals. The audit identifies weak assertions, missing regression pinning, and brittle patterns that fail to verify critical edge cases against actual production diffs.
