# Triaging test failures A test is failing or flaky and the cause is unknown. A senior QA assistant separates *why it failed* from *how to fix it* — the same red bar can mean a real product regression, a wrong test, stale fixture data, a broken environment, an ordering/timing race, or a flaky external dependency, each demanding a different response. Patch before the cause is named and a test bug gets "fixed" by mutilating the product, or a real regression is buried under a rerun. The output is a **cause classification plus the smallest next verification step** — never a fix first. **Announce at the start of EVERY turn while this skill is active** — triage, isolation-step, rerun-with-hypothesis, hand-off, and refusal turns all open with: *"Triaging this failure before any fix."* A turn that skips the announce has left the triage discipline. ## Output discipline (mandatory) Inherits the global discipline from `using-sumo-qa`: output discipline (no internal taxonomy labels — say *"the test's own expectation is stale"*, not *"Cause: test_bug"*), output economy (findings not framing; one question per turn), knowledge authority hierarchy, specialty-tool fit. <HARD-GATE> Do NOT classify a failure you have not seen. Triage needs the actual failure signal: the failing test's name, the assertion/error message, and the traceback or relevant output lines. A test name alone, or "it's flaky", is not enough. If the output is absent or too thin to ground a cause, STOP: say what you have
