Next Steps (Priority Order)

  1. Create Application Unit Tests Project

    • Create new test project
    • Add required NuGet packages (xUnit, FluentAssertions, Moq/NSubstitute)
    • Reference Application and Domain projects
  2. Implement Command Validator Tests

    • Start with most critical validators (RegisterTenant, Login)
    • 5-8 tests per validator
    • Estimated: 1-2 hours
  3. Implement Command Handler Tests with Mocks

    • Focus on Day 8 handlers first (UpdateUserRole, ResendVerification)
    • Setup proper mocking infrastructure
    • 6-10 tests per handler
    • Estimated: 2-3 hours
  4. Enhance Integration Tests

    • Add Day 8 feature tests
    • Add edge case tests
    • Estimated: 4 hours
  5. Add Security and Performance Tests

    • Security tests for enumeration prevention
    • Performance benchmarks
    • Estimated: 3-4 hours
  6. Create Test Infrastructure

    • Build fluent builders for test data
    • Create shared fixtures
    • Estimated: 1-2 hours
  7. Final Test Run and Report

    • Run all tests (unit + integration)
    • Generate coverage report
    • Document findings

Current Test Statistics

Category Tests Passing Status
Domain Unit Tests 113 113 (100%) COMPLETE
Application Unit Tests 0 - ⚠️ TODO
Integration Tests (existing) 77 64 (83.1%) ⚠️ NEEDS ENHANCEMENT
Day 8 Features Integration 0 - ⚠️ TODO
Edge Case Tests 0 - ⚠️ TODO
Security Tests 0 - ⚠️ TODO
Performance Tests 0 - ⚠️ TODO
TOTAL (Current) 190 177 (93.2%) In Progress
TOTAL (Target) 240+ ≥ 228 (95%) Target

Recommendations

  1. Prioritize Day 8 Features: Since these are new features, they need comprehensive testing immediately

  2. Mock Strategy: Use Moq or NSubstitute for Application layer tests to isolate business logic

  3. Integration Test Database: Use test containers or in-memory database for integration tests

  4. Test Data Management: Implement builders pattern to reduce test setup boilerplate

  5. CI/CD Integration: Ensure all tests run automatically on PR/commit

  6. Coverage Tooling: Use coverlet to measure code coverage (target: 80%+)

  7. Performance Baseline: Establish performance benchmarks early to detect regressions

Conclusion

Part 1 (Domain Unit Tests) is COMPLETE with 113 tests covering all domain entities comprehensively. All tests are passing with 100% success rate.

The remaining work focuses on:

  • Application layer unit tests with mocks
  • Integration tests for Day 8 features
  • Security and performance testing
  • Test infrastructure for maintainability

Estimated Total Time Remaining: 15-18 hours (2 working days)
