How can I use mock servers in my integration tests?

Using mock servers in integration tests allows you to simulate API responses without relying on actual services. This helps in testing your application in isolation.

What are the benefits of using mock servers?

Mock servers can speed up tests, reduce dependencies on external services, and allow for testing edge cases that might be hard to replicate with real APIs.

Can you give me an example of setting up a mock server?

Sure! You can use tools like WireMock or MockServer. For example, with WireMock, you can create a stub for a GET request like this: stubFor(get(urlEqualTo("/api/resource")).willReturn(aResponse().withStatus(200).withBody("{\"key\":\"value\"}")));.

How do I integrate this with my testing framework?

You can integrate mock servers with frameworks like JUnit or Mocha by starting the server before your tests run and stopping it afterward. This ensures your tests can communicate with the mock server.
