# Unit Test Generator

For `[[behavior]]`, produce a test plan with:

1. Happy path tests.
2. Edge cases and invalid input.
3. Regression tests for previously broken behavior.
4. Mocks, fixtures, and assertions needed.
5. Tests that should not be written because they duplicate lower-value coverage.
