Coverage

alirezarezvani/claude-skills

Generates code coverage reports for your Playwright tests, showing you exactly which parts of your application are being exercised during test runs. You'd reach for this when you need to identify untested code paths or justify your testing investment to stakeholders who love metrics. The skill handles both v8 coverage collection and Istanbul-style instrumentation, depending on what you're testing. It's genuinely useful for catching blind spots in your test suite, though don't fall into the trap of chasing 100% coverage at the expense of meaningful test scenarios. Works best as a periodic checkup rather than a gate on every commit.

Analyze Test Coverage Gaps

Map all testable surfaces in the application and identify what's tested vs. what's missing.

Steps

1. Map Application Surface

Use the Explore subagent to catalog:

Routes/Pages:

  • Scan route definitions (Next.js app/, React Router config, Vue Router, etc.)
  • List all user-facing pages with their paths

Components:

  • Identify interactive components (forms, modals, dropdowns, tables)
  • Note components with complex state logic

API Endpoints:

  • Scan API route files or backend controllers
  • List all endpoints with their methods

User Flows:

  • Identify critical paths: auth, checkout, onboarding, core features
  • Map multi-step workflows

2. Map Existing Tests

Scan all *.spec.ts / *.spec.js files:

  • Extract which pages/routes are covered (by page.goto() calls)
  • Extract which components are tested (by locator usage)
  • Extract which API endpoints are mocked or hit
  • Count tests per area

3. Generate Coverage Matrix
