SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill systematically identifies the root cause of failing regression tests, saving developers significant debugging time and effort.

Core Features & Use Cases

  • Automated Analysis: Analyzes code changes, error messages, and test dependencies to pinpoint failure origins.
  • Structured Reporting: Generates clear markdown reports ranking likely causes with evidence and suggested fixes.
  • Use Case: When your CI pipeline suddenly starts failing due to a regression, use this Skill to quickly understand if a recent code commit or a dependency change is the culprit, and get actionable insights to fix it.

Quick Start

Use the regression-root-cause-analyzer skill to find why the 'test_user_creation' test is failing.

FAQPage Schema
How do I find the root cause of a failing regression test in my CI pipeline?

Finding the root cause of a failing regression test involves analyzing recent git diffs, stack traces, and test dependencies. By examining code changes and error messages from CI pipelines, you systematically pinpoint failure origins and rank likely causes with evidence.

What is the best way to debug intermittent test breakages after a code commit?

Debugging intermittent test breakages is best done by investigating regressions after code commits through structured analysis. This method examines git diffs and dependency changes to produce ranked reports of likely causes, clarifying whether a recent commit introduced the fault.

Can I use stack traces and git diffs to investigate test failures?

Yes, you can investigate test failures by analyzing stack traces and git diffs together. Examining these elements alongside test dependencies systematically identifies failure origins and clarifies how specific code changes triggered the regression.

How do I identify if a dependency change caused my regression test to fail?

To identify if a dependency change caused your regression test to fail, analyze the test dependencies alongside recent code changes. Comparing git diffs and error messages helps determine whether an updated dependency or a new code commit introduced the fault.

Does this root cause analysis approach work for CI/CD debugging?

Yes, this root cause analysis approach works for CI/CD debugging. It is specifically designed to investigate failing regression tests within CI pipelines by analyzing code changes, error messages, and dependency shifts to pinpoint the exact failure origin.

What are the limitations of automated root cause analysis for failing tests?

The limitations of automated root cause analysis for failing tests include its dependency on the quality of available git diffs, stack traces, and error messages. Without clear dependency change logs or structured commit data, pinpointing exact failure origins becomes less precise.
