FAQ
What does this tool tell you?
The Test Suite Health Calculator scores test suite health from flakiness rate, total run time, coverage, and maintenance burden with prioritized improvement recommendations.
What affects the result most?
Test suite health: coverage + flakiness + speed + pyramid shape + maintenance burden. Healthy signals: <5% flaky, <10 min total run, >80% coverage, pyramid-shaped, <10% maintenance time. Sick signals: >10% flaky, >30 min run, <60% coverage, ice-cream-cone shaped, >30% maintenance time.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
