🧪 Testing & Quality Assurance

🧪 Unit Tests

# Test fraud detection engine
class TestFraudEngine(unittest.TestCase):
    def setUp(self):
        self.engine = FraudEngine()
    
    def test_anomaly_detection(self):
        # Test with known anomaly patterns
        anomalous_data = self.generate_anomalous_data()
        result = self.engine.detect_fraud(anomalous_data)
        
        self.assertTrue(result.is_fraud)
        self.assertGreater(result.confidence, 0.8)
    
    def test_normal_behavior(self):
        # Test with normal behavior patterns
        normal_data = self.generate_normal_data()
        result = self.engine.detect_fraud(normal_data)
        
        self.assertFalse(result.is_fraud)
        self.assertLess(result.confidence, 0.3)

🔍 Integration Tests

# Test API integration
class TestAPIIntegration(unittest.TestCase):
    def setUp(self):
        self.client = TestClient(app)
    
    def test_security_endpoint(self):
        response = self.client.post('/api/security/scan', 
                                  json={'pipeline_id': 'test-123'})
        
        self.assertEqual(response.status_code, 200)
        self.assertIn('risk_score', response.json())
    
    def test_blockchain_integration(self):
        response = self.client.post('/api/blockchain/log-event',
                                  json={'event_type': 'test', 'data': 'test-data'})
        
        self.assertEqual(response.status_code, 201)
        self.assertIn('transaction_hash', response.json())

📊 Performance Testing

# Load testing with Locust
class SecurityAPILoadTest(HttpUser):
    wait_time = between(1, 3)
    
    def on_start(self):
        self.client.post('/api/auth/login', json={
            'username': 'test_user',
            'password': 'test_password'
        })
    
    @task
    def scan_pipeline(self):
        self.client.get('/api/security/scan/pipeline-123')
    
    @task
    def check_threats(self):
        self.client.get('/api/threats/active')
