Core Features & Use Cases

  • Analyze Coverage Reports: Review Jest coverage output to pinpoint untested code.
  • Identify Untested Paths: Determine which parts of your codebase lack sufficient test coverage.
  • Improve Coverage: Guide efforts to add new tests for uncovered code to meet defined targets.
  • Use Case: After running your test suite, you notice coverage has dropped below 80%. Use this Skill to analyze the report and identify the specific files and lines of code that need more tests.

Quick Start

Analyze the latest test coverage report to identify areas needing improvement.

Frequently Asked Questions about af-test-coverage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I identify untested code paths from Jest coverage output?▼

To identify untested code paths from Jest coverage output, you analyze the coverage report metrics to pinpoint specific files and lines lacking sufficient test coverage. This skill reviews the generated report to locate exact code needing tests.

What is the best way to prioritize adding tests for low-coverage areas in my codebase?▼

Prioritizing tests for low-coverage areas involves analyzing coverage metrics to identify the most critical untested code paths. This skill guides improvements by targeting specific files and lines that lack coverage to help meet quality targets.

Can I use this to review Jest coverage reports if my test coverage drops below 80%?▼

Yes, you can review Jest coverage reports when test coverage drops below targets like 80%. The analysis identifies specific untested files and lines, guiding you on exactly where to add new tests to improve overall code quality.

How does analyzing test coverage metrics help improve code quality?▼

Analyzing test coverage metrics improves code quality by identifying gaps in the test suite where untested code paths exist. This ensures your codebase is thoroughly tested and meets defined quality targets by prioritizing necessary test additions.

Do I need to configure dependencies to analyze test coverage reports?▼

No external dependencies are required to analyze test coverage reports. The skill operates independently to review Jest coverage output and identify low-coverage areas, requiring only your existing coverage metrics as input to function.
