What it does
Find the untested code paths that actually matter, not just the coverage percentage. Use after adding tests.
Coverage Gaps
Coverage % is a vanity metric. Hunt the gaps that bite:
- Error paths, the 500, the timeout, the empty/null input, the malformed payload. Almost always untested.
- Boundaries, 0, 1, max, off-by-one, empty collection.
- Branches, every
if/elseandcatchexercised, not just the happy line. - Concurrency / order, anything stateful tested in isolation AND in sequence. Skip tests that assert a constructor sets a property, worthless. Test behavior, not implementation. Output: the 3-5 highest-risk untested paths, ranked by blast radius, with the test to add.
