Test Coverage: Achieve >80% test coverage

[OneByJorah]

Test Coverage Gap

Current State: No tests exist in the codebase. Zero test coverage.

Required:

1. Backend (Python/FastAPI/Flask):

   • Add pytest with pytest-cov
   • Unit tests for auth routes (login, register, password change)
   • Unit tests for streams CRUD
   • Unit tests for recordings CRUD
   • Unit tests for events CRUD
   • Unit tests for schedules CRUD
   • Unit tests for analytics
   • Unit tests for backup
   • Unit tests for health check
   • Integration tests with test database
   • Target: >80% coverage

2. Frontend (React):

   • Add Jest + React Testing Library
   • Component tests for Dashboard, Login, Settings, Timeline
   • API integration tests
   • Target: >80% coverage

3. FFmpeg Processor:

   • Unit tests for event saving, cleanup functions
   • Mock FFmpeg subprocess calls

4. Add to CI pipeline:

   • Coverage reporting (Codecov or similar)
   • Fail build if coverage drops below 80%

Priority: HIGH
