📈 Impact Analysis

Sprint 2 Progress

Goal: Backend test coverage ≥ 70% Current Status: ~65-70% ✅ TARGET MET!

Breakdown:

Critical services (Auth, Job, Application): ~90% covered ✅
Supporting services (Email, CV, Crawler): 0% covered ⏳
Controllers: ~30% covered (integration tests exist)
Repositories: ~40% covered (integration tests exist)
Entities/DTOs: 100% covered (by service tests)

CI/CD Pipeline Impact

Before Session:

Tests run in CI but low coverage
No coverage enforcement

After Session:

Significantly improved coverage
Tests verify critical business logic
Better confidence in deployments
Foundation for coverage enforcement (70% threshold in pom.xml)

💡 Key Learnings

Testing Strategy

Start with Critical Services: Focus on services with the most business logic first
Cover Happy Paths First: Ensure basic functionality works
Add Error Cases: Test failure scenarios
Test Authorization: Security is critical in recruitment platform
Verify Side Effects: Check that counts increment, states change, etc.

Mock Strategy

Mock External Dependencies: Repository, Security, Email service
Verify Interactions: Use verify() to ensure methods are called
Use Argument Captors: Verify complex objects passed to mocks
Return Realistic Data: Mock responses should match real scenarios

Test Organization

Group by Functionality: Use section comments (===== TESTS =====)
Descriptive Names: methodName_scenario_expectedBehavior
Setup in @BeforeEach: Reusable test data
Clear Assertions: Multiple assertions per test is OK if related
