Playwright Documentation Root Cause

Playwright Root Cause Analysis

Use this skill when a failure needs explanation, not just rerunning.

Inputs

• failing test output,
• trace artifacts, screenshots, videos, or HTML reports when available,
• related console, network, or application logs,
• recent code or requirement changes if they help explain the failure.

Analysis Workflow

1. Identify the failing assertion or stopping point.
2. Reconstruct what the app and test were each expecting.
3. Classify the issue as likely product bug, test defect, environment issue, or possible flake.
4. Support the classification with concrete evidence.

Output Contract

Provide:

• Failure
• Most likely cause
• Classification
• Evidence
• Recommended next action
• Confidence

Guardrails

• Do not claim certainty when the evidence is mixed.
• Separate observation from hypothesis.
• If the right answer is "needs reproduction with more data," say that directly.
