```bash
# Verify current system status
curl -f https://api.yourdomain.com/health
curl -f https://yourdomain.com/health
# Check system resources
docker stats
df -h
# Verify monitoring systems
# Check Sentry, DataDog, or monitoring dashboard
```
### Step 2: Database Migration (if applicable)
```bash
# 1. Create database backup
pg_dump $DATABASE_URL > backup_$(date +%Y%m%d_%H%M%S).sql
# 2. Run migration in staging (verify first)
npm run migrate:staging
# 3. Verify migration succeeded
npm run migrate:status
# 4. Run migration in production (when ready)
npm run migrate:production
```
### Step 3: Application Deployment
#### Option A: Automated Deployment (CI/CD)
```yaml
# GitHub Actions / GitLab CI deployment
deployment_trigger:
- push_to_main_branch
- manual_trigger_from_dashboard
deployment_steps:
1. run_automated_tests
2. build_application
3. deploy_to_staging
4. run_smoke_tests
5. wait_for_approval
6. deploy_to_production
7. run_post_deployment_tests
```
#### Option B: Manual Deployment
```bash
# 1. Pull latest code
git checkout main
git pull origin main
# 2. Install dependencies
npm ci --production
# 3. Build application
npm run build
# 4. Deploy using platform-specific commands
# Vercel
vercel --prod
# Heroku
git push heroku main
# Docker
docker build -t app:latest .
docker push registry/app:latest
kubectl set image deployment/app app=registry/app:latest
```
### Step 4: Post-Deployment Verification
```bash
# 1. Health checks

curl -f https://yourdomain.com/health
# 2. Smoke tests
npm run test:smoke:production
# 3. Verify key functionality
curl -X POST https://api.yourdomain.com/api/auth/login \
-H "Content-Type: application/json" \
-d '{"email":"test@example.com","password":"test123"}'
# 4. Check error rates and performance
# Monitor for first 30 minutes after deployment
```
## Monitoring & Alerting
### Key Metrics to Monitor
```yaml
application_metrics:
- response_time_p95: < 500ms
- error_rate: < 1%

```
## Rollback Plan
### When to Rollback
- Critical application errors affecting > 10% of users
- Data corruption or data loss incidents
- Security vulnerabilities exposed
- Performance degradation > 50% from baseline
- Core functionality completely broken
### Rollback Procedure
```bash
# Option 1: Platform rollback (recommended)
# Vercel
vercel rollback [deployment-url]
# Heroku
heroku rollback v[previous-version]
# Kubernetes
kubectl rollout undo deployment/app
# Option 2: Git revert (if platform rollback unavailable)
git revert HEAD
git push origin main
# Option 3: Database rollback (if needed)
# Restore from backup taken before deployment
pg_restore -d $DATABASE_URL backup_[timestamp].sql
```
### Post-Rollback Actions
1. **Immediate**: Verify system stability
2. **Within 1 hour**: Investigate root cause
3. **Within 4 hours**: Fix identified issues
4. **Within 24 hours**: Plan and execute re-deployment

it('should [expected behavior] when [condition]', () => {
// Arrange
const input = { /* test data */ };
// Act
const result = functionUnderTest(input);
// Assert
expect(result).toEqual(expectedOutput);
});
});
describe('Error Handling', () => {
it('should throw error when [invalid condition]', () => {
