Generates unit tests, integration tests, and E2E tests for React/Next.js applications. Scans components to create Jest + React Testing Library test stubs, analyzes Istanbul/LCOV coverage reports to surface gaps, scaffolds Playwright test files from Next.js routes, mocks API calls with MSW, creates test fixtures, and configures test runners. Use when the user asks to "generate tests", "write unit tests", "analyze test coverage", "scaffold E2E tests", "set up Playwright", "configure Jest", "implement testing patterns", or "improve test quality".
npx skills add alirezarezvani/claude-skills --skill senior-qa
Test automation, coverage analysis, and quality assurance patterns for React and Next.js applications.
Scans React/TypeScript components and generates Jest + React Testing Library test stubs with proper structure.
Input: Source directory containing React components Output: Test files with describe blocks, render tests, interaction tests
Usage:
Supported Patterns:
Parses Jest/Istanbul coverage reports and identifies gaps, uncovered branches, and provides actionable recommendations.
Input: Coverage report (JSON or LCOV format) Output: Coverage analysis with recommendations
Usage:
Scans Next.js pages/app directory and generates Playwright test files with common interactions.
Input: Next.js pages or app directory Output: Playwright test files organized by route
Usage:
Use when setting up tests for new or existing React components.
Step 1: Scan project for untested components
Step 2: Generate test stubs
Step 3: Review and customize generated tests
Step 4: Run tests and check coverage
Use when improving test coverage or preparing for release.
Step 1: Generate coverage report
Step 2: Analyze coverage gaps
Step 3: Identify critical paths
Step 4: Generate missing test stubs
Step 5: Verify improvement
Use when setting up Playwright for a Next.js project.
Step 1: Initialize Playwright (if not installed)
Step 2: Scaffold E2E tests from routes
Step 3: Configure authentication fixtures
Step 4: Run E2E tests
Step 5: Add to CI pipeline
