Why Automate Testing?
Manual testing can't keep up with modern development pace. If deployment happens every day, manually checking everything is simply impossible. Automation provides faster feedback and fewer bugs in production.
Testing Pyramid
Unit tests (base) — fast, cheap, many. Test individual functions in isolation. Goal: 70-80% of all tests.
Integration tests (middle) — verify module collaboration, API endpoints, database operations. Goal: 15-20%.
E2E tests (top) — simulate user journey through the entire application. Slow, fragile, but irreplaceable for critical scenarios. Goal: 5-10%.
Tool Selection
- Unit: Jest (JavaScript), pytest (Python), JUnit (Java)
- API: Postman/Newman, REST Assured, Supertest
- E2E: Playwright (our recommendation), Cypress, Selenium
- Performance: k6, JMeter, Gatling
CI/CD Integration
Tests without automation pipeline are only half the solution. Set up:
- Unit tests — on every commit (should execute in <30 seconds)
- Integration tests — on every PR (up to 5 minutes)
- E2E tests — before deployment to staging/production (up to 15 minutes)
Where to Start?
If you currently have no tests — don't start with E2E. Start with unit tests for the most critical business logic. 20 good unit tests will give more than 2 unstable E2E tests.
