Automated Testing with Mock APIs

Build comprehensive test suites using mock APIs for reliable, fast automation

Testing Pyramid with Mock APIs

Mock API Builder enables you to create comprehensive test suites across all levels of the testing pyramid—from unit tests to end-to-end tests—without depending on real backend services.

Unit Tests

Test individual functions and components with mocked API responses

Integration Tests

Test API integrations and data flows with live mock endpoints

E2E Tests

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
