Unit tests that catch bugs, not just run code.
Guides writing behavior-focused unit tests and configuring coverage gates that fail when coverage falls below the threshold.
When to use it
Use for unit testing, test doubles, coverage thresholds, mutation testing, fake timers, and snapshot tests with Jest, Vitest, or pytest.
It changes how the agent structures unit tests and configures and verifies coverage gates in the project.
