Direct Answer: Implementing automated testing and CI/CD pipelines is essential for maintaining software quality while ensuring rapid release cycles. Adhering to the "Test Pyramid"—balancing unit, integration, and E2E tests—is critical. By automating the workflow from Pull Request to production deployment using tools like GitHub Actions and Vitest, teams can build a safe, stable, and highly efficient development environment.
Ensuring Quality with Automated Testing and CI/CD
Automated testing and CI/CD pipelines are essential for maintaining software quality while shipping fast.
The Test Pyramid
```
E2E Tests (few)
Integration Tests (moderate)
Unit Tests (many)
```
Balance tests at each level for optimal coverage and speed.
CI/CD Pipeline Structure
1. On Pull Request
- ESLint code checks
- TypeScript type checking
- Unit test execution
2. Post-merge
- Integration tests
- Build and deploy to staging
3. Production Release
- E2E tests (Playwright)
- Lighthouse performance checks
- Production deployment
Tool Stack
- Test runner: Vitest (unit) / Playwright (E2E)
- CI/CD: GitHub Actions
- Deploy: Cloudflare Pages
- Monitoring: Sentry (errors) / Lighthouse CI (performance)
DONOMI's Quality Standards
All DONOMI projects standardize CI/CD pipeline setup, enabling safe and rapid release cycles.
Q: What is the Test Pyramid?
A: It is a concept that recommends having many unit tests, moderate integration tests, and fewer E2E tests for optimal balance.
Q: When do CI/CD pipelines run?
A: They typically run upon Pull Request creation, after merging code into the main branch, and during production deployment.
Q: What tools does DONOMI use for testing and CI/CD?
A: We use Vitest and Playwright for testing, GitHub Actions for CI/CD, and Cloudflare Pages for deployment.
