Phase 5: Testing and Deployment (Week 12-13)

Week 12: Testing

1. Backend Testing

   • Implement comprehensive unit tests for critical services:
     • Garmin sync service (mock API responses)
     • AI service (mock OpenRouter API)
     • Workflow services (plan generation, evolution)
   • API endpoint testing with realistic payloads
   • Error handling and edge case testing
   • Database operation tests (including rollback scenarios)

   Example test for Garmin service:

   # tests/test_garmin_service.py
   import pytest
   from unittest.mock import AsyncMock, patch
   from app.services.garmin import GarminService
   from app.exceptions import GarminAuthError
   
   @pytest.mark.asyncio
   async def test_garmin_auth_failure():
       with patch('garth.Client', side_effect=Exception("Auth failed")):
           service = GarminService()
           with pytest.raises(GarminAuthError):
               await service.authenticate()
   

2. Integration Testing

   • Test full Garmin sync workflow: authentication → activity fetch → storage
   • Verify AI analysis pipeline: workout → analysis → plan evolution
   • Database transaction tests across multiple operations
   • File system integration tests (GPX upload/download)

3. Frontend Testing

   • Component tests using React Testing Library
   • User workflow tests (upload GPX → generate plan → analyze workout)
   • API response handling and error display tests
   • Responsive design verification across devices

   Example component test:

   // frontend/src/components/__tests__/GarminSync.test.jsx
   import { render, screen, fireEvent } from '@testing-library/react';
   import GarminSync from '../GarminSync';
   
   test('shows sync status after triggering', async () => {
       render(<GarminSync />);
       fireEvent.click(screen.getByText('Sync Recent Activities'));
       expect(await screen.findByText('Syncing...')).toBeInTheDocument();
   });
   

4. Continuous Integration Setup

   • Configure GitHub Actions pipeline:
     • Backend test suite (Python)
     • Frontend test suite (Jest)
     • Security scanning (dependencies, secrets)
     • Docker image builds on successful tests
   • Automated database migration checks
   • Test coverage reporting

Week 13: Deployment Preparation

1. Environment Configuration

   # .env.production
   GARMIN_USERNAME=your_garmin_email
   GARMIN_PASSWORD=your_garmin_password
   OPENROUTER_API_KEY=your_openrouter_key
   AI_MODEL=anthropic/claude-3-sonnet-20240229
   API_KEY=your_secure_api_key
   

2. Production Docker Setup

   • Optimize Dockerfiles for production:
     • Multi-stage builds
     • Minimized image sizes
     • Proper user permissions
   • Health checks for all services
   • Resource limits in docker-compose.prod.yml

3. Backup Strategy

   • Implement daily automated backups:
     • Database (pg_dump)
     • GPX files
     • Garmin sessions
   • Backup rotation (keep last 30 days)
   • Verify restore procedure

4. Monitoring and Logging

   • Structured logging with log rotation
   • System health dashboard
   • Error tracking and alerting
   • Performance monitoring
