OpenClaw 评估

The skill's code, instructions, and required actions are consistent with its stated purpose (generating tests and analyzing coverage for React/Next.js apps), but you should review generated artifacts and the included scripts before running them because the package has no published homepage and its origin is unknown.

name: "senior-qa"
description: 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".

# Senior QA Engineer

Test automation, coverage analysis, and quality assurance patterns for React and Next.js applications.

---

## Quick Start

```bash
# Generate Jest test stubs for React components
python scripts/test_suite_generator.py src/components/ --output __tests__/

# Analyze test coverage from Jest/Istanbul reports
python scripts/coverage_analyzer.py coverage/coverage-final.json --threshold 80

# Scaffold Playwright E2E tests for Next.js routes
python scripts/e2e_test_scaffolder.py src/app/ --output e2e/
```

---

## Tools Overview

### 1. Test Suite Generator

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:**
```bash
# Basic usage - scan components and generate tests
python scripts/test_suite_generator.py src/components/ --output __tests__/

# Include accessibility tests
python scripts/test_suite_generator.py src/ --output __tests__/ --include-a11y

# Generate with custom template
python scripts/test_suite_generator.py src/ --template custom-template.tsx
```

**Supported Patterns:**
- Functional components with hooks
- Components with Context providers
- Components with data fetching
- Form components with validation

---

### 2. Coverage Analyzer

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:**
```bash
# Analyze coverage report
python scripts/coverage_analyzer.py coverage/coverage-final.json

# Enforce threshold (exit 1 if below)
python scripts/coverage_analyzer.py coverage/ --threshold 80 --strict

# Generate HTML report
python scripts/coverage_analyzer.py coverage/ --format html --output report.html
```

---

### 3. E2E Test Scaffolder

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:**
```bash
# Scaffold E2E tests for Next.js App Router
python scripts/e2e_test_scaffolder.py src/app/ --output e2e/

# Include Page Object Model classes
python scripts/e2e_test_scaffolder.py src/app/ --output e2e/ --include-pom

# Generate for specific routes
python scripts/e2e_test_scaffolder.py src/app/ --routes "/login,/dashboard,/checkout"
```

## QA Workflows

### Unit Test Generation Workflow

Use when setting up tests for new or existing React components.

**Step 1: Scan project for untested components**
```bash
python scripts/test_suite_generator.py src/components/ --scan-only
```

**Step 2: Generate test stubs**
```bash
python scripts/test_suite_generator.py src/components/ --output __tests__/
```

**Step 3: Review and customize generated tests**
```typescript
// __tests__/Button.test.tsx (generated)
import { render, screen, fireEvent } from '@testing-library/react';
import { Button } from '../src/components/Button';

describe('Button', () => {
  it('renders with label', () => {
    render(<Button>Click me</Button>);
    expect(screen.getByRole('button', { name: "click-mei-tobeinthedocument"
  });

  it('calls onClick when clicked', () => {
    const handleClick = jest.fn();
    render(<Button onClick={handleClick}>Click</Button>);
    fireEvent.click(screen.getByRole('button'));
    expect(handleClick).toHaveBeenCalledTimes(1);
  });

  // TODO: Add your specific test cases
});
```

**Step 4: Run tests and check coverage**
```bash
npm test -- --coverage
python scripts/coverage_analyzer.py coverage/coverage-final.json
```

---

### Coverage Analysis Workflow

Use when improving test coverage or preparing for release.

**Step 1: Generate coverage report**
```bash
npm test -- --coverage --coverageReporters=json
```

**Step 2: Analyze coverage gaps**
```bash
python scripts/coverage_analyzer.py coverage/coverage-final.json --threshold 80
```

**Step 3: Identify critical paths**
```bash
python scripts/coverage_analyzer.py coverage/ --critical-paths
```

**Step 4: Generate missing test stubs**
```bash
python scripts/test_suite_generator.py src/ --uncovered-only --output __tests__/
```

**Step 5: Verify improvement**
```bash
npm test -- --coverage
python scripts/coverage_analyzer.py coverage/ --compare previous-coverage.json
```

---

### E2E Test Setup Workflow

Use when setting up Playwright for a Next.js project.

**Step 1: Initialize Playwright (if not installed)**
```bash
npm init playwright@latest
```

**Step 2: Scaffold E2E tests from routes**
```bash
python scripts/e2e_test_scaffolder.py src/app/ --output e2e/
```

**Step 3: Configure authentication fixtures**
```typescript
// e2e/fixtures/auth.ts (generated)
import { test as base } from '@playwright/test';

export const test = base.extend({
  authenticatedPage: async ({ page }, use) => {
    await page.goto('/login');
    await page.fill('[name="email"]', 'test@example.com');
    await page.fill('[name="password"]', 'password');
    await page.click('button[type="submit"]');
    await page.waitForURL('/dashboard');
    await use(page);
  },
});
```

**Step 4: Run E2E tests**
```bash
npx playwright test
npx playwright show-report
```

**Step 5: Add to CI pipeline**
```yaml
# .github/workflows/e2e.yml
- name: "run-e2e-tests"
  run: npx playwright test
- name: "upload-report"
  uses: actions/upload-artifact@v3
  with:
    name: "playwright-report"
    path: playwright-report/
```

## Common Patterns Quick Reference

### React Testing Library Queries

```typescript
// Preferred (accessible)
screen.getByRole('button', { name: "submiti"
screen.getByLabelText(/email/i)
screen.getByPlaceholderText(/search/i)

// Fallback
screen.getByTestId('custom-element')
```

### Async Testing

```typescript
// Wait for element
await screen.findByText(/loaded/i);

// Wait for removal
await waitForElementToBeRemoved(() => screen.queryByText(/loading/i));

// Wait for condition
await waitFor(() => {
  expect(mockFn).toHaveBeenCalled();
});
```

### Mocking with MSW

```typescript
import { rest } from 'msw';
import { setupServer } from 'msw/node';

const server = setupServer(
  rest.get('/api/users', (req, res, ctx) => {
    return res(ctx.json([{ id: 1, name: "john" }]));
  })
);

beforeAll(() => server.listen());
afterEach(() => server.resetHandlers());
afterAll(() => server.close());
```

### Playwright Locators

```typescript
// Preferred
page.getByRole('button', { name: "submit" })
page.getByLabel('Email')
page.getByText('Welcome')

// Chaining
page.getByRole('listitem').filter({ hasText: 'Product' })
```

### Coverage Thresholds (jest.config.js)

```javascript
module.exports = {
  coverageThreshold: {
    global: {
      branches: 80,
      functions: 80,
      lines: 80,
      statements: 80,
    },
  },
};
```
