SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill helps you quickly identify the specific code change or commit that introduced a regression, turning a failing test or feature into actionable insights.

Core Features & Use Cases

  • Automated Bisecting: Leverages git bisect to efficiently narrow down the commit range where a regression occurred.
  • Root Cause Identification: Guides you to the exact commit and code hunk responsible for the breakage.
  • Use Case: When a previously working feature suddenly fails in your CI pipeline, use this Skill to find out which commit broke it and why.

Quick Start

Use the regression-root-cause-analyzer skill to find the commit that broke the 'user-deletion' test, starting from 'main' and knowing it worked on tag 'v2.3.0'.

FAQPage Schema
How do I find which commit introduced a regression using git bisect?▼

To find a regression, you bisect commit history by providing a known good state and a bad state where the test fails, allowing the tool to automatically narrow down the exact commit responsible for the breakage.

What do I need to automate root cause analysis for failing tests?▼

Automating root cause analysis requires Git command-line integration and a verifiable test oracle to automatically evaluate each commit during the bisection process and pinpoint the code hunk responsible.

When should I use automated commit analysis for debugging?▼

Use automated commit analysis when a previously functional feature or test case in your CI pipeline has started failing and you need to quickly identify the specific code change that introduced the regression.

Can I identify the root cause of a regression without a verifiable test oracle?▼

No, a verifiable test oracle is required for automated bisecting because the tool needs an automated way to evaluate whether each checked-out commit state is passing or failing to narrow down the commit range.

What is the best way to debug a feature that suddenly broke in my CI pipeline?▼

The best way to debug a suddenly failing CI pipeline feature is using automated regression analysis to bisect commit history between a known working tag and the current broken state to pinpoint the exact offending commit.
