Stop Doing E2E Tests! Write Better Tests with Contract

Tired of brittle end-to-end tests? It’s time to write better tests with contract testing. In this session, Markus Oberlehner from the Austrian Federal Computing Centre shares how to test web applications that communicate with HTTP APIs more effectively. Discover why mocking network requests can lead to false confidence and learn how contract testing with Specmatic allows you to test your entire app in isolation without mocks.

You’ll get practical insights on using OpenAPI specs, running stub servers, and writing Playwright tests that connect frontend and backend seamlessly in frameworks like Next.js, Nuxt, or Remix. Say goodbye to flaky E2E tests and hello to confidence and speed in your testing workflows.
