QA Automation

QA Automation Skill

AI-powered QA engineering — Playwright generation, test strategy, coverage analysis.

Quick Start

/qa-automation                              # Auto-detect what needs testing
/qa-automation --feature=playwright         # Generate Playwright E2E tests
/qa-automation --feature=strategy           # Test strategy for current code
/qa-automation --feature=coverage           # Coverage gap analysis
/qa-automation --feature=accessibility      # WCAG/a11y audit
/qa-automation --feature=e2e                # E2E test plan
/qa-automation --feature=api-tests          # API endpoint tests
/qa-automation --feature=unit-stubs         # Unit test stubs/boilerplate

Features

Playwright Generation

/qa-automation --feature=playwright --file=src/auth/login.js

Output: Ready-to-run Playwright script

// Generated: tests/e2e/auth/login.spec.ts
import { test, expect } from '@playwright/test';

test.describe('Login Flow', () => {
  test('successful login with valid credentials', async ({ page }) => {
    await page.goto('/login');
    await page.getByLabel('Email').fill('user@example.com');
    await page.getByLabel('Password').fill('password');
    await page.getByRole('button', { name: 'Login' }).click();
    await expect(page).toHaveURL('/dashboard');
  });

  test('shows error on invalid credentials', async ({ page }) => {
    // ... generated from code analysis
  });
});

Smart generation:

• Uses accessible selectors (getByRole, getByLabel, getByText)
• MCP browser tree integration (not brittle CSS selectors)
• Self-healing test patterns
• Covers happy path + error states + edge cases

Test Strategy

/qa-automation --feature=strategy --quick    # Strategy for changed files

Output:

## Test Strategy for: feat/auth-oauth

### Unit Tests (Jest)
- authService.validateToken() — 4 test cases
- tokenRefresh() — 3 test cases (incl. expiry edge case)

### Integration Tests
- POST /auth/login — request/response contract
- POST /auth/refresh — token rotation

### E2E Tests (Playwright)
- Login flow → dashboard
- Token expiry → auto-refresh → continue
- Invalid credentials → error message

### Coverage target: 85%+ on new code
### Priority: OAuth token refresh (highest risk path)

Coverage Gap Analysis

/qa-automation --feature=coverage

Identifies:

• Uncovered branches (switch cases, error paths)
• Functions with 0 tests
• Lines never executed
• Edge cases not tested (null, empty, boundary values)

Output: Ranked list of coverage gaps with test stubs to fill them

Accessibility Testing

WCAG 2.1 AA standards:

• Missing ARIA labels/roles
• Color contrast failures
• Keyboard navigation gaps
• Focus management issues
• Screen reader compatibility

Scope Flags

/qa-automation --quick          # Changed files only
/qa-automation --full           # All source files
/qa-automation --file=path      # Specific file
/qa-automation --feature=X      # Single feature

Memory Updates

After each session, updates:

• Test patterns established
• Coverage baseline
• Known flaky test areas
• Playwright config decisions

Integration

/test-global --checks=jest          # Run generated tests
/pr-check --checks=coverage         # Validate coverage gates
/orchestrate --phase=pre-release    # Full QA before release
