Next Steps

Immediate (Next 24 Hours)

  1. Complete remaining handler tests (recommendation, conversion)
  2. Add conversion service tests
  3. Add analytics service tests

This Week

  1. Create protocol client expanded tests
  2. Create integration test suite
  3. Create stress test suite
  4. Run full test suite and verify coverage

Next Week (Week 3)

  1. Begin Phase 2: Frontend & Mobile Test Coverage
  2. Start Android unit test fixes
  3. Expand frontend component tests

Risks & Mitigations

Risk Impact Probability Mitigation
Test coverage takes longer Medium Medium Parallel execution, accept 90% if needed
Integration test complexity Medium Low Use mock servers, incremental approach
Android test failures Low Medium Fix assertion issues, not production code

Conclusion

Phase 0 is successfully complete with full security infrastructure in place. Phase 1 is progressing well with 230+ new test cases added. The expanded test coverage is on track to reach the 95% target within the planned timeline.

The project continues to maintain high code quality standards with zero lint warnings and comprehensive security scanning capabilities.
