Flaky test cost
Put a monthly cost on flaky tests that fail pipelines and get rerun.
Quality & testingHow it's worked out
- Cost = runs × flaky share × days × minutes ÷ 60 × people × hourly cost
- Each flaky failure costs one investigation and rerun
NoteThe bigger cost is trust: when red builds are often flaky, people ignore real failures. Quarantine flaky tests and fix the noisiest first.
