# Test Failure Triage

Canonical: https://automationtester.in/tools/test-failure-triage

Paste a test-runner error, CI excerpt, or stack trace and classify it with deterministic rules. The web workflow runs in the browser, makes no request with the input, and does not store logs, output, file names, lengths, selectors, tokens, or identifiers.

## Output
- Classification and transparent confidence
- Likely cause
- First repair to try
- Diagnostic checks
- Stable link to a maintained failure guide
- Copyable Markdown summary
