Testing Anti-Patterns

Your unit tests might be verifying mock behavior instead of real behavior. Testing anti-patterns like incomplete mocks or testing mock interactions create false confidence by validating that mocks were called rather than asserting actual business logic outcomes.

Common testing anti-patterns include testing mock behavior rather than real outcomes, creating test-only production code to enable mocking, and implementing incomplete mocks. These anti-patterns undermine TDD practices by failing to verify actual software behavior and deep dependency interactions.

To fix test-only production code, reason about deep dependency understanding and prefer testing at the correct integration level. Implement practical gate checks to curb unsafe mocks, enforcing TDD practices to keep production code clean and ensure tests verify real behavior.

Prefer testing real behavior in integration tests to verify deep dependencies. Before introducing mocks, reason about whether you are testing real behavior, and apply practical gate checks to curb unsafe mocks, ensuring your integration tests validate actual system interactions.

Yes, TDD practices catch issues early and keep production code clean. Guided TDD practices enforce deep dependency understanding and provide practical gate checks to curb unsafe mocks and incomplete mocks, ensuring tests verify real behavior throughout development and refactoring.
