Can you tell me more about your experience with WireMock: how did you set it up and use it?

In my experience, WireMock was used to simulate external HTTP services during automated testing.

WireMock was usually run as a standalone server or embedded in tests via a library. For example, starting a WireMockServer in Java tests:

WireMockServer wireMockServer = new WireMockServer(options().port(8080));
wireMockServer.start();

wireMockServer.stubFor(get(urlEqualTo("/api/data"))
    .willReturn(aResponse()
        .withStatus(200)
        .withHeader("Content-Type", "application/json")
        .withBody("{\"key\":\"value\"}")));

// The code under test makes a request to http://localhost:8080/api/data

wireMockServer.stop();

WireMock was used for:

• isolating tests from real services,
• testing handling of various responses (success, errors, timeouts),
• configuring scenarios with different responses for different requests.

This helped improve test stability and speed, as well as cover cases that are difficult to reproduce with real services.
