wiremock AutoConfigureWireMock HttpHostConnectException: Connection refused

Question

@ActiveProfiles("it")
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(classes = ServiceApplication.class)
@AutoConfigureWireMock(port = 0)
@TestPropertySource(properties = {
        "server.servlet.context-path=http://localhost:${wiremock.server.port}/abc"
})
public class ABCTest {

    
    @Autowired
    protected TestRestTemplate restTemplate;

    private static final String INIT_URL = "/init";

    private static final String JSON_RESPONSE = """
            {"result":...
            "generatedAt":"2025-10-06T06:46:28.745Z"}
    """;

    @BeforeClass
    public void beforeClass() {
    }

    @Test
    public void init() throws IOException {


        stubFor(get(urlEqualTo("/abc" + INIT_URL))
                .willReturn(aResponse()
                        .withStatus(status)
                        .withHeader("Content-Type", "application/json")
                        .withBody(JSON_RESPONSE)));

        HttpHeaders headers = new HttpHeaders();
        headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
        headers.add("X-API-KEY", apiKey);
        HttpEntity<String> entity = new HttpEntity<>("body", headers);
        ResponseEntity<String> response = restTemplate.exchange(INIT_URL, HttpMethod.GET, entity, String.class);

        System.out.println(response.getBody());
       
    }

I received this:

wiremock.org.apache.hc.client5.http.HttpHostConnectException: Connect to http://localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused

i used spring-cloud-contract-wiremock-4.3.0.jar and spring-boot-test-3.5.4.jar

Your configuration is weird. Why the server.servlet.context-path? That doesn't make sense. — M. Deinum

as M. Deinum pointed out, the server.servlet.context-path property is weird.

Just remove the @TestPropertySource annotation from your test class.

For more information, see my explanation below. Also, if the issue persists, please provide us more details regarding your project, like Java version, settings for the "it" Profile, and so on.

I tried to reproduce your project as close as I can, here are my versions & dependencies:

Java version: JDK17
Spring Boot: 3.5.4
Spring Cloud: 2024.0.1
My dependencies: spring-boot-starter-web, spring-boot-starter-test (test scope), spring-cloud-starter-contract-stub-runner (test scope), wiremock-jre8-standalone (test scope)

Just removing the @TestPropertySource annotation with the server.servlet.context-path property:

@ActiveProfiles("it")
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(classes = ServiceApplication.class)
@AutoConfigureWireMock(port = 0)
public class ABCTest {
   // ...
}

Made my test green:

mvn test -Dtest=ABCTest
