Test Quality Analysis

Expert knowledge for analyzing and improving test quality - detecting test smells, overmocking, insufficient coverage, and testing anti-patterns.

Core Dimensions

• Correctness: Tests verify the right behavior
• Reliability: Tests are deterministic, not flaky
• Maintainability: Tests are easy to understand
• Performance: Tests run quickly
• Coverage: Tests cover critical code paths
• Isolation: Tests don't depend on external state

Test Smells

Overmocking

Problem: Mocking too many dependencies makes tests fragile.
