# QA Process Documentation

## Overview
This document outlines the comprehensive QA process for Pluro Accessibility Copilot, including test automation, coverage requirements, and quality assurance strategies.

## Test Coverage Requirements

### Minimum Coverage Targets
- **Overall Coverage**: 80% (currently at 86.78%)
- **Critical Modules**: 90% (scanner/core, types)
- **API Modules**: 85% (currently needs improvement)
- **Utility Modules**: 80% (currently at 74.62%)


## Test Automation Strategy

### Unit Tests
- **Coverage**: All business logic functions
- **Framework**: Jest
- **Location**: `src/test/unit/`
- **Execution**: `np test`

### Integration Tests
- **Coverage**: Module interactions and workflows
- **Framework**: Jest
- **Location**: `src/test/integration/`
- **Execution**: `npm test --testPathPattern=integration`

### E2E Tests
- **Coverage**: Complete user workflows
- **Framework**: Playwright (planned)
- **Location**: `tests/e2e/`
- **Execution**: `npm run test:e2e`

## Test Categories

### 1. Accessibility Scanner Tests
- Color contrast detection
- ARIA attribute validation
- Semantic HTML structure
- Keyboard navigation support
- Screen reader compatibility

### 2. Rule Engine Tests
- Custom rule validation
- Dynamic rule loading
- Rule conflict resolution
- Performance optimization

### 3. API Integration Tests
- Configuration management
- Error handling
- Rate limiting
- Data validation

### 4. UI/UX Tests
- Extension activation
- Panel rendering
- Quick fix functionality
- Settings management

## Automated Testing Workflow

### Pre-commit Hooks
```bash
# Run linting
npm run lint

# Run unit tests
npm test

# Check coverage
npm run test:coverage
```

### CI/CD Pipeline
```yaml
# GitHub Actions workflow
name: QA Pipeline
on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: '18'
      - run: npm ci
      - run: npm test
      - run: npm run test:coverage
      - run: npm run lint
```

## Test Data Management

### Test Fixtures
- **Location**: `qa/test-cases/`
- **Types**: HTML, CSS, JavaScript, TypeScript
- **Coverage**: Various accessibility scenarios

### Mock Data
- **API Responses**: Mocked for offline testing
- **VSCode API**: Mocked for unit testing
- **File System**: In-memory for isolation

## Performance Testing

### Load Testing
- **Tool**: Artillery.js
- **Scenarios**: Multiple file scanning
- **Metrics**: Response time, memory usage

### Memory Testing
- **Tool**: Node.js --inspect
- **Focus**: Memory leaks in scanners
- **Threshold**: < 100MB for large files

## Security Testing

### Static Analysis
- **Tool**: ESLint security rules
- **Focus**: Code injection, XSS prevention
- **Execution**: `npm run lint:security`

### Dependency Scanning
- **Tool**: npm audit
- **Frequency**: Weekly
- **Action**: Auto-update when safe

## Bug Tracking and Reporting

### Issue Templates
- **Bug Report**: Standardized format
- **Feature Request**: User story format
- **Test Case**: Step-by-step reproduction

### Quality Metrics
- **Bug Density**: < 1 bug per 1000 lines
- **Test Reliability**: > 99% pass rate
- **Coverage Stability**: < 5% variance

## Continuous Improvement

### Regular Reviews
- **Weekly**: Test coverage analysis
- **Monthly**: Performance benchmark
- **Quarterly**: Security audit

### Feedback Loop
- **User Reports**: Integration with GitHub Issues
- **Automated Alerts**: Coverage drops, test failures
- **Team Retrospectives**: Process improvement

## Tools and Resources

### Testing Tools
- **Jest**: Unit and integration testing
- **Playwright**: E2E testing (planned)
- **Istanbul**: Coverage reporting
- **ESLint**: Code quality and security

### Monitoring Tools
- **GitHub Actions**: CI/CD pipeline
- **Codecov**: Coverage tracking
- **Snyk**: Security monitoring

## Best Practices

### Test Writing
1. **Arrange-Act-Assert**: Clear test structure
2. **Descriptive Names**: Self-documenting tests
3. **Isolation**: Independent test execution
4. **Fast Execution**: < 5 seconds per test suite

### Coverage Strategy
1. **Critical Paths**: 100% coverage for core logic
2. **Edge Cases**: Comprehensive error handling
3. **Integration Points**: API and UI boundaries
4. **Performance**: Load and stress testing

### Maintenance
1. **Regular Updates**: Keep dependencies current
2. **Refactoring**: Improve test quality over time
3. **Documentation**: Keep test docs updated
4. **Monitoring**: Track metrics and trends
