3. Automation Strategy (automation_strategy.md)

# Automation Strategy: [Feature Name]

## Framework Selection

### Mobile (React Native)
**Framework:** Jest + React Native Testing Library + Detox

**Rationale:**
- Jest: Built-in with React Native, fast, good DX
- RNTL: Best practice for RN component testing
- Detox: Most stable E2E for React Native

**Setup:**
```bash
yarn add --dev @testing-library/react-native detox

Web (Vue.js)

{userFlow}.e2e.test.ts              # E2E tests

Mocking Strategy

API Mocks

// Mock at API client level
jest.mock('api/socialMediaApi', () => ({
  postToFacebook: jest.fn().mockResolvedValue({
    id: 'post-123',
    status: 'published',
  }),
}));

Navigation Mocks

// Mock navigation
const mockNavigate = jest.fn();
jest.mock('@react-navigation/native', () => ({
  useNavigation: () => ({ navigate: mockNavigate }),
}));

Store Mocks

// Mock Zustand store
jest.mock('hooks/useBoundStore', () => ({
  useBoundStore: () => ({
    user: { id: '1', name: 'Test User' },
    setUser: jest.fn(),
  }),
}));

Test Data Management

Factory Pattern

// testUtils/factories.ts
export const createMockUser = (overrides = {}) => ({
  id: 'user-123',
  name: 'Test User',
  email: 'test@example.com',
  ...overrides,
});

export const createMockPost = (overrides = {}) => ({
  id: 'post-123',
  content: 'Test content',
  platform: 'facebook',
  ...overrides,
});

CI/CD Integration

  inputs:
    versionSpec: '18.x'

- script: |
    yarn install --frozen-lockfile
    yarn test --coverage --maxWorkers=2
  displayName: 'Run Tests'

- task: PublishCodeCoverageResults@1
  inputs:
    codeCoverageTool: 'Cobertura'
    summaryFileLocation: 'coverage/cobertura-coverage.xml'

Coverage Thresholds

// jest.config.js
{
  "coverageThreshold": {
    "global": {
      "statements": 80,
      "branches": 75,
      "functions": 80,
      "lines": 80

Jest Configuration

{
  "maxWorkers": "50%",
  "testTimeout": 10000
}

Detox Configuration

{
  "testRunner": "jest",
  "runnerConfig": "e2e/config.json",
  "behavior": {
    "init": {
      "exposeGlobals": false
    }
  },
  "configurations": {
    "ios.sim": {
      "device": { "type": "iPhone 14" }
    }
  }
}

Reporting

Coverage Reports

• Publish to: Azure Pipelines / CI

Test Results

• Format: JUnit XML
• Output: test-results/ directory
• Integration: CI dashboard

E2E Reports

Maintenance Plan

Flaky Test Management

1. Identify flaky tests (failure rate > 5%)
2. Add to flakyTests.json for tracking
3. Implement retry logic (max 2 retries)
4. Fix root cause within 1 sprint

Test Review Cycle

• Weekly: Review test coverage trends
• Monthly: Update test data
• Quarterly: Framework version updates

## 🚀 TDD Enforcement

### TDD Workflow

🔴 RED Phase ├── Write failing test ├── Ensure test fails for right reason └── APPROVAL GATE

🟢 GREEN Phase ├── Write minimum code to pass ├── Run tests, ensure pass └── APPROVAL GATE

♻️ REFACTOR Phase ├── Improve code quality ├── Ensure tests still pass └── APPROVAL GATE

### Verification Checklist
Before allowing code generation:
- [ ] Test file exists
- [ ] Test cases cover requirements
- [ ] Test fails (RED phase)
- [ ] Coverage impact calculated

### Blocking Conditions
**BLOCK** code generation if:
- No test file created
- Coverage will drop below threshold
- Critical path not covered
- TDD mode enabled but skipped

📊 Test Case Writing Guidelines

Good Test Structure

describe('useSocialMediaPost', () => {
  // Setup
  beforeEach(() => {
    jest.clearAllMocks();
  });

  // Organized by feature
  describe('when posting to Facebook', () => {
    it('should successfully post with valid content', async () => {
      // Arrange
      const { result } = renderHook(() => useSocialMediaPost());
      const mockPost = createMockPost({ platform: 'facebook' });
      
      // Act
      await act(async () => {
        await result.current.post(mockPost);
      });
      
      // Assert
      expect(result.current.status).toBe('success');
      expect(facebookApi.post).toHaveBeenCalledWith(mockPost);
    });
    
    it('should handle API errors gracefully', async () => {
      // Arrange
      const { result } = renderHook(() => useSocialMediaPost());
      facebookApi.post.mockRejectedValue(new Error('API Error'));
      
      // Act
      await act(async () => {
        await result.current.post(mockPost);
      });
      
      // Assert
      expect(result.current.status).toBe('error');
      expect(result.current.error).toBe('API Error');
    });
  });
  
  describe('when retrying failed posts', () => {
    // ... retry tests
  });
});

Test Naming Convention

Pattern: should [expected behavior] when [condition]

Good:
✅ should display error message when API returns 400
✅ should disable submit button when form is invalid
✅ should retry post when network error occurs

Bad:
❌ test post
❌ error handling
❌ it works

Coverage of Edge Cases

// Happy path
it('should post successfully with valid data', ...)

// Validation
it('should reject empty content', ...)
it('should reject content exceeding 5000 chars', ...)

// Error scenarios
it('should handle network timeout', ...)
it('should handle API rate limit (429)', ...)
it('should handle unauthorized (401)', ...)

// Edge cases
it('should handle posting to disconnected platform', ...)
it('should handle media upload failure', ...)
it('should handle multi-platform partial failure', ...)

// Concurrency
it('should prevent duplicate posts when clicked multiple times', ...)

// Accessibility
it('should have proper ARIA labels', ...)
it('should be keyboard navigable', ...)

🔍 Test Review Checklist

When reviewing tests:

Structure

• Tests are organized by feature/behavior
• Descriptive test names (should...when...)
• Proper setup/teardown (beforeEach, afterEach)
• No test interdependencies

Quality

• Tests are independent and isolated
• Mocks are properly reset between tests
• No hard-coded values (use factories)
• No test.skip or test.only (except WIP)

Coverage

• Happy path covered
• Error scenarios covered
• Edge cases covered
• Coverage meets threshold

Maintainability

• Tests are readable
• Comments explain "why" not "what"
• Reusable test utilities extracted
• No flaky tests (timing issues, race conditions)

Performance

• Tests run in reasonable time (< 5s per suite)
• Expensive operations mocked
• No unnecessary delays

---

⚠️ Common Testing Anti-Patterns to Avoid

❌ Anti-Pattern 1: Testing Implementation Details

// BAD
it('should call useState hook', () => {
  expect(mockUseState).toHaveBeenCalled();
});

// GOOD
it('should display username when provided', () => {
  const { getByText } = render(<User name="John" />);
  expect(getByText('John')).toBeTruthy();
});

❌ Anti-Pattern 2: Flaky Tests with Timers

// BAD
it('should show message after delay', () => {
  renderComponent();
  setTimeout(() => {
    expect(getByText('Message')).toBeTruthy();
  }, 1000); // Flaky!
});

// GOOD
it('should show message after delay', async () => {
  renderComponent();
  await waitFor(() => {
    expect(getByText('Message')).toBeTruthy();
  });
});

❌ Anti-Pattern 3: Testing Multiple Things in One Test

// BAD
it('should do everything', () => {
  // Tests 10 different things
});

// GOOD
it('should validate email format', () => { ... });
it('should submit form when valid', () => { ... });
it('should display error when invalid', () => { ... });
