Hi, I am using spring boot 3.2 + witemock-standalone 3.3.1.

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebClient(registerRestTemplate = true)
class BookApiServiceITest {

  @RegisterExtension
  static WireMockExtension wireMockServer =
      WireMockExtension.newInstance()
          .options(wireMockConfig().dynamicPort().usingFilesUnderClasspath("wiremock"))
          .build();

  @Autowired private BookApiService bookApiService;

  @test
  void testCreateEntitlement() {
    stubFor(
        post(urlEqualTo("/entitlement"))
            .willReturn(
                aResponse()
                    .withStatus(200)
                    .withHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
                    .withHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE)
                    .withBody("{\"result\": \"success\"}")));
    BookEntitlementResponse entitlement =
        bookApiService.createEntitlement(bookObject, "product");
  }
}

When I run the test getting below exception, Do we need to set any static port & host to run the testcases?

Try adding

.configureStaticDsl(true)

to the config builder
