Connection refused when using wiremock

I have this piece of code in a Junit, where I clearly set the port to 8888

when(clientUtils.getLinkUrl(eq(HOSTELS_MICROSERVICE.name()), eq(HOSTELS_MICROSERVICE.name()), anyMap()))
                .thenReturn("http://localhost:8888/HOSTELS/HOSTELSMethods");

stubFor(com.github.tomakehurst.wiremock.client.WireMock.get("/HOSTELS/HOSTELS_LIST").willReturn(
                aResponse().withStatus(200)
                        .withHeader("Content-Type", APPLICATION_JSON_VALUE)
                        .withBody(ResourceUtils.getResourceFileAsString ("__files/HOSTELS.json"))));

but when I run the test I got this error on this line:

stubFor(com.github.tomakehurst.wiremock.client.WireMock.get("/HOSTELS/HOSTELS_LIST").willReturn(..

and the error:

wiremock.org.apache.http.conn.HttpHostConnectException: Connect to localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

For Java users

Based on the WireMock docs.

There are 3 possibilities to use WireMock in your tests :

  1. If you are using Wiremock as JUnit 4 rule to configure the port use :
import static com.github.tomakehurst.wiremock.core.WireMockConfiguration.wireMockConfig;

...

@Rule
public WireMockRule wireMockRule = new WireMockRule(wireMockConfig().port(8888));
  1. If you are using new instance and start it from your Test class (for example @Before) :
import static com.github.tomakehurst.wiremock.core.WireMockConfiguration.options;

...

public class Test {

    WireMockServer wm;

    @BeforeEach
    void setUp() {
        wm = new WireMockServer(options().port(8888));
        wm.start();
    }

    @Test
    void test() {
        wm.stubFor(...);
    }
}
  1. With static configuration of default instance (not using new instance in your test) :
WireMock.configureFor(8888);

For Kotlin users

If you are using kotlin you can add actual wiremock instance to stubFor and verify calls like wm.stubFor() and configure the port like in option 3 of this answer.
