analyzing-test-coverage

## Overview This skill enables Claude to analyze code coverage metrics, pinpoint areas of untested code, and generate detailed reports. It helps you identify gaps in your test suite and ensure comprehensive code coverage. ## How It Works 1. **Coverage Data Collection**: Claude executes the project's test suite with coverage tracking enabled (e.g., using `nyc`, `coverage.py`, or JaCoCo). 2. **Report Generation**: The plugin parses the coverage data and generates a detailed report, including metrics for line, branch, function, and statement coverage. 3. **Uncovered Code Identification**: Claude highlights specific lines or blocks of code that are not covered by any tests. ## When to Use This Skill This skill activates when you need to: - Analyze the overall code coverage of your project. - Identify specific areas of code that lack test coverage. - Generate a detailed report of code coverage metrics. - Enforce minimum code coverage thresholds. ## Examples ### Example 1: Analyzing Project Coverage User request: "Analyze code coverage for the entire project" The skill will: 1. Execute the project's test suite with coverage tracking. 2. Generate a comprehensive coverage report, showing line, branch, and function coverage. ### Example 2: Identifying Untested Code User request: "Show me the untested code in the `src/utils.js` file" The skill will: 1. Analyze the coverage data for `src/utils.js`. 2. Highlight the lines of code in `src/utils.js` that are not covered by any ...
