How can I create mock servers in Java?

You can create mock servers in Java using libraries like Mockito or WireMock. Would you like a code example?

Yes, please provide a code example using WireMock.

Sure! Here's a simple example:

import static com.github.tomakehurst.wiremock.client.WireMock.*;

public class MockServerExample {
    public static void main(String[] args) {
        WireMockServer wireMockServer = new WireMockServer();
        wireMockServer.start();

        wireMockServer.stubFor(get(urlEqualTo("/api/test"))
            .willReturn(aResponse()
            .withHeader("Content-Type", "application/json")
            .withBody("{\"message\":\"Hello, World!\"}")
        ));

        // Your test code here

        wireMockServer.stop();
    }
}

This sets up a mock server that responds to GET requests at /api/test.

What are the advantages of using mock servers?

Mock servers allow you to test your application without relying on external services, making tests faster and more reliable.

Can I use mock servers for integration testing?

Absolutely! Mock servers are great for integration testing as they simulate the behavior of external APIs.
