Tests that check real behavior, not your mocks.
Guides developers to write tests that verify real behavior without unnecessary mocks or test-only production methods.
When to use it
Use when writing or changing tests, adding mocks, or considering test-only methods in production code.
It changes how the agent writes and modifies project tests by requiring real-behavior assertions, informed mocking, and separation of test utilities from production classes.
