Failure Analysis Report
Root Cause Found: Database Connection Refused.
Pattern: 1 root cause -> 4 cascading failures.
Fix: The DB server is down. Run docker compose up -d postgres.
Impact: Fixing the DB connection will resolve 80% of current failures.

About this skill
What it does
The Test Failure Analyzer transforms messy, overwhelming test logs into structured engineering intelligence. It automatically parses raw output from major testing frameworks—including pytest, Jest, Go test, and JUnit—to classify failures, identify root causes, and suggest targeted fixes.
Why use this skill
Debugging a failing CI pipeline or a massive refactor shouldn't feel like finding a needle in a haystack. This skill goes beyond reporting failures; it detects cascading failure chains. If a single database connection error causes 20 tests to fail, the analyzer identifies that root cause so you don't waste time triaging 19 downstream symptoms.
Supported Tools & Frameworks
- Languages: Python, JavaScript/TypeScript, Go, Ruby, PHP, Java, Rust.
- Frameworks: pytest, unittest, Jest, Vitest, Go test, Mocha, RSpec, PHPUnit, JUnit, Cargo test.
- Environments: Local terminal output or CI/CD logs (GitHub Actions, GitLab CI, Jenkins).
The Result
You receive a clean Failure Analysis Report featuring a prioritized table of failures, severity levels (Critical to Low), and a step-by-step remediation plan with estimated impact. It’s like having a Senior QA Engineer instantly triage your PR.
