FlakySuite

Monte Carlo flaky-suite simulator: drag flake rate and suite size, see P(suite green) per retry budget from 2,000 runs.

default / 3% flake, 40 tests

A 3% flake rate sounds harmless until you multiply it by 40 tests. Drag the sliders and watch the no-retry bar collapse.

Per-test flakiness compounds with suite size. Retries buy green builds, not trust.
