SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents accidental decreases in test coverage by enforcing a high-water mark for each package, ensuring that code quality doesn't regress over time.

Core Features & Use Cases

Enforce Coverage Baselines: Automatically compare current test coverage against historical high-water marks.
Flag Regressions: Identify and report packages where coverage has decreased.
Threshold Checking: Ensure packages meet minimum coverage requirements.
Use Case: Integrate this into your CI pipeline to automatically fail builds if test coverage for any critical package drops below its established baseline.

Quick Start

Run the coverage ratcheting skill to check current test coverage against the baseline.

FAQPage Schema

How do I prevent test coverage drops in a Go CI pipeline?▼

Prevent test coverage drops by enforcing a strict high-water mark for each Go package. The Skill analyzes coverage reports, compares them against historical baselines, flags any package decreases, and fails the CI build if minimum thresholds are not met.

What is coverage ratcheting and how does it work?▼

Coverage ratcheting is a technique that enforces a strict high-water mark for test coverage per package. It works by analyzing coverage reports, comparing current results against historical baselines, and flagging any regressions where package coverage has decreased.

Can I fail CI builds automatically when code coverage regresses?▼

Yes, you can fail CI builds automatically when code coverage regresses. Integrating this into your pipeline checks current coverage against historical high-water marks and fails the build if critical packages drop below their established baselines or minimum thresholds.

Does this coverage enforcement require shell access to run Go tests?▼

Yes, this coverage enforcement requires shell access to run Go tests and parse coverage data. It needs this environment access to analyze coverage reports, compare them against historical high-water marks, and identify packages with coverage regressions.

How do I check current Go test coverage against a historical baseline?▼

To check current Go test coverage against a historical baseline, run the coverage ratcheting process to analyze coverage reports. It compares current results against established high-water marks, flags any decreases, and verifies packages meet minimum threshold requirements.
