🔍 Test Data Management

Test User Creation

// Create test user
$userData = [
    'username' => 'testuser',
    'email' => 'test@example.com',
    'password' => 'TestPassword123!'
];
$result = $auth->register($userData);

Test Data Cleanup

// Automatic cleanup in tearDown()
private function cleanupTestData() {
    // Remove test users and related data
    // Clear sessions and temporary data
}

Database Fixtures

• tests/fixtures/test_data.sql provides sample data
• Automatic test user creation and cleanup
• Isolated test database environment

🚨 Common Test Failures

Database Connection Issues

# Check database service
docker-compose -f docker-compose.test.yml ps

# View database logs
docker-compose -f docker-compose.test.yml logs test-db

Permission Issues

# Fix file permissions
chmod -R 777 f_data/
chmod -R 755 tests/

Memory Issues

# Increase PHP memory limit
php -d memory_limit=512M vendor/bin/phpunit

Session Issues

# Clear session data
rm -rf f_data/sessions/*

🎯 Test Best Practices

Writing New Tests

1. Arrange-Act-Assert: Structure tests clearly
2. Isolation: Each test should be independent
3. Descriptive Names: Use clear test method names
4. Edge Cases: Test boundary conditions
5. Cleanup: Always clean up test data

Security Testing

1. Input Validation: Test all input sanitization
2. Authentication: Test login and session management
3. Authorization: Test permission checking
4. Data Protection: Test sensitive data handling

Performance Testing

1. Benchmarks: Set realistic performance targets
2. Load Testing: Test under concurrent load
3. Memory Monitoring: Track memory usage
4. Optimization: Identify bottlenecks

🚀 Continuous Integration

GitHub Actions Workflow

• Automated testing on push/PR
• Multiple test environments
• Code coverage reporting
• Performance benchmarking

Test Stages

1. Syntax Check: PHP syntax validation
2. Unit Tests: Individual component testing
3. Integration Tests: Workflow testing
4. Security Tests: Vulnerability scanning
5. Performance Tests: Load testing
