Microservices Testing
Test Pyramid für Microservices
Basis: Unit Tests
- Schnell und isoliert
- Business Logic testen
- Mocking von Dependencies
- Hohe Abdeckung (>80%)
Mitte: Integration Tests
- Service-Integration
- Datenbank-Tests
- API Tests
- External Service Mocking
Spitze: E2E Tests
- Vollständige Workflows
- Echte Umgebung
- Wenige, kritische Pfade
- Langsamer, teurer
Contract Testing
Consumer-Driven Contracts
- Consumer definiert Erwartungen
- Provider verifiziert
- Unabhängiges Testen
- Frühe Feedback-Schleife
Pact Framework
- Contract Definition
- Pact Broker
- Provider Verification
- Versionierung
Spring Cloud Contract
- Groovy DSL
- Stub Generation
- Integration mit Spring
Component Testing
- Service in Isolation
- Testcontainers
- In-Memory Databases
- WireMock für Externe
Integration Testing
Service-to-Service
- Tatsächliche API-Calls
- Test Environment
- Docker Compose Setup
Database Integration
- Schema Migration Tests
- Data Access Tests
- Testcontainers PostgreSQL/MySQL
E2E Testing
Strategien
- Happy Path fokussiert
- Kritische Business Flows
- Smoke Tests nach Deploy
Tools
- Playwright, Cypress (Web)
- k6, Artillery (Load)
- Postman/Newman (API)
Chaos Testing
Chaos Engineering
- Failure Injection
- Resilience Validation
- Production-like Environment
Tools
- Chaos Monkey
- Litmus

Performance Testing
- Load Testing (k6, Gatling)
- Stress Testing
- Soak Testing
- Baseline Metrics
Best Practices
- Test in Production-like Environment
- Testcontainers für Dependencies
- Contract Tests zwischen Teams
- Parallelisierung von Tests
- Test Data Management
CI/CD Integration
- Tests in Pipeline
- Quality Gates
- Test Reports
- Flaky Test Detection
