FAQPage Schema
How do I generate a test coverage report for a Vitest workspace?▼

To generate a test coverage report, this Skill aggregates Vitest coverage data from coverage-final.json or coverage-summary.json files and outputs a consolidated markdown report at /docs/test-coverage.md.

How does test coverage visualization work for identifying uncovered code?▼

Test coverage visualization renders mermaid charts highlighting top uncovered lines, functions, and branches, translating raw coverage metrics into visual hotspots for quick quality assessment.

Can I use this to aggregate coverage metrics across multiple projects?▼

Yes, you can aggregate coverage metrics across multiple projects in a workspace by reading the coverage data from each project's respective coverage/ directory and consolidating it into a single report.

What coverage data formats are needed to generate the mermaid visualizations?▼

The mermaid visualizations require Vitest coverage data in JSON format, specifically reading from the coverage-final.json or coverage-summary.json files located inside the project coverage directories.

Does this test coverage report generation support CI/CD quality gates?▼

Yes, the report generation supports a practical workflow for CI/CD quality gates by providing configurable top-N rankings of uncovered areas to monitor code quality thresholds during pipeline execution.

How do I configure top-N rankings for uncovered code hotspots?▼

You can configure top-N rankings for uncovered code hotspots when generating the report, allowing you to limit the mermaid visualizations to the most critical uncovered lines, functions, and branches.
