feat(cli): add --retry <n> to re-run failed tests#756
Merged
Conversation
Re-run a failed test up to N extra times (--retry <n> / BASHUNIT_RETRY), reporting it passed if any attempt passes. Retry wraps only test execution; the parse/report/counter path runs once on the final attempt, so nothing is double-counted and each --parallel fork retries itself. Tests that only pass on retry are annotated '(retry n/m)'. Disabled by default. Closes #737

🤔 Background
Related #737
Flaky tests (timing, network, filesystem races) fail intermittently and poison CI. A bounded retry lets a genuinely-flaky test recover while a consistently-broken one still fails, without hiding real failures.
💡 Changes
--retry <n>flag andBASHUNIT_RETRYenv var; a failed test is re-run up to N extra times and reported passed if any attempt passes. Disabled by default (0).--parallelfork retries itself.(retry n/m)so flakiness stays visible; composes with--stop-on-failure.
