This is a structured framework for turning Linear bug tickets into failing regression tests for n8n workflows. It walks through parsing ticket signals, routing to the right test layer (Jest unit, integration, Vitest, or Playwright), tracing the code path, and writing a test that proves the bug exists without fixing it. The routing table is smart, mapping affected areas like nodes, triggers, or UI components to specific test patterns and locations. It knows when to bail (needs real API credentials, race conditions, cloud infrastructure) and outputs a confidence score from CONFIRMED to SKIPPED. Honestly most useful if you're maintaining n8n itself or a large fork, since it's tailored to their package structure and testing conventions. Saves you from the "where do I even start" paralysis when facing a vague bug report.
