Testing Best Practices
- ✓Use dedicated test projects separate mock APIs for testing to avoid affecting development
- ✓Test all HTTP methods verify GET, POST, PUT, PATCH, DELETE work correctly
- ✓Test error scenarios verify handling of 404, 500, and other error responses
- ✓Use environment variables configure API URLs via env vars, never hardcode
- ✓Isolate test data each test should be independent and not rely on previous tests
- ✓Test authentication flows verify login, token handling, and protected routes
- ✓Run tests in CI/CD automate test execution on every commit
- ✓Measure coverage aim for 80%+ code coverage on critical paths
