Prioritize tests by behavior and risk rather than line coverage. Reject tests that only mirror implementation. Keep negative cases, malformed data, authorization, timeouts, and duplicates visible.
Objective
improve meaningful coverage.
Context
behavior contract, existing tests, coverage and mutation or failure history.
Decompose
identify risk gaps, write boundary and negative tests, run mutation or fault tests, delete redundant tests.
Criteria
tests fail for the targeted defect and do not merely mirror implementation.
Review
reject tests that assert mocks rather than behavior.
Output
gap matrix, new tests, remaining untested risks.
Handoff checklist
- Targeted failure demonstrated
- Negative paths included
- Tests assert behavior
- Remaining gaps are named
