Development Workflow

​
Git Workflow

​
Development Process

  1. Create Feature Branch
    • git checkout -b feature/new-feature
    • Follow naming convention: feature/description
  2. Development
    • Write code following TypeScript best practices
    • Implement responsive design for mobile and web
    • Add proper error handling and validation
  3. Testing
    • Write unit tests for new functionality
    • Test on multiple devices and browsers
    • Verify Firebase integration
  4. Code Review
    • Create pull request with detailed description
    • Request review from team members
    • Address feedback and make changes
  1. Issue Identification
    • Reproduce the bug consistently
    • Document steps to reproduce
    • Identify root cause
  2. Fix Implementation
    • Create bug fix branch: bugfix/issue-description
    • Implement minimal fix
    • Add regression tests
  3. Testing & Validation
    • Test fix thoroughly
    • Verify no new issues introduced
    • Test on affected platforms
  1. Critical Issue
    • Create hotfix branch from main
    • Implement immediate fix
    • Minimal testing for critical path
  2. Emergency Deployment
    • Deploy to production immediately
    • Monitor for issues
    • Merge back to develop branch

​
Testing Strategy

​
Testing Pyramid

​
Testing Implementation

Unit Testing

Tools: Jest, React Testing Library Coverage: Components, utilities, hooks Location: __tests__ directories Command: npm test

Integration Testing

Tools: Firebase Emulator, Supertest Coverage: API endpoints, database operations Location: tests/integration Command: npm run test:integration

E2E Testing

Tools: Cypress, Detox Coverage: Complete user workflows Location: tests/e2e Command: npm run test:e2e

Performance Testing

Tools: Lighthouse, Firebase Performance Coverage: Load times, bundle size Location: Performance monitoring Command: npm run test:performance

​
Deployment Process

​
Deployment Architecture

​
Deployment Workflows

1

Web Dashboard Deployment

npm run build

# Deploy to Vercel
npm run deploy

# Verify deployment
curl -I https://talatalk-admin.vercel.app
2

Mobile App Deployment

# Build for production
expo build:android

# Submit to app stores
expo submit:android
3

Firebase Deployment

# Deploy Firebase rules and functions
