You can evaluate test suite quality by scoring tests against Farley's eight properties: Understandable, Maintainable, Repeatable, Atomic, Necessary, Granular, Fast, and First. The review generates a structured Farley Score with per-property evidence and concrete improvement recommendations.

Dave Farley's approach assesses test maintainability and repeatability by checking if tests are easy to understand, deterministic, and isolated. This structured evaluation identifies gaps in test quality and prioritizes refactors for new features.

To review a TDD codebase for early test-driven design signals, provide your test files or project path to evaluate the First property. This detects early test-driven design signals and delivers evidence-backed recommendations to raise overall test quality.

You can use this test review method on individual test files or entire test suites across TDD-focused codebases. It evaluates understandability, maintainability, repeatability, atomicity, necessity, granularity, speed, and early test-driven design signals at both levels.

The best way to identify which tests need refactoring is to generate a Farley Score that evaluates tests against eight quality properties. This structured evaluation highlights specific gaps and offers concrete, evidence-backed recommendations to prioritize refactors.

Your test suite scores low on atomicity and granularity because tests may be testing multiple behaviors simultaneously or running at an inappropriate scope. The review evaluates these specific properties, provides evidence from your codebase, and recommends targeted improvements.
