I am writing integration test to mock external local service called dates-service-svc which actually runs on port 8081 . I am using wireMock to mock the service and HTTP client to issue a request to dates-services-svc , but the requests issued by HTTP client doesn't hit the wireMock . and raises an "connection refused " exception . when the test case finish its execution . the logs says

Requests received: [ ]

On the other hand ,I issued the request using the post man . wireMock replies with that The requested URL matches the stub registered

I configured the wireMock as following

@Rule
    public WireMockRule wireMockServer = new WireMockRule(new WireMockConfiguration().port(8084)
            .notifier(new ConsoleNotifier(true)));

@Before
    public void setUp() {
        wireMockServer.start();
        WireMock.configureFor("localhost", 8084);
    }

    @AfterEach
    public void afterEach() {
        wireMockServer.resetAll();
    }

    @After
    public void tearUp() {
        wireMockServer.stop();
    }

I created very simple test cases to just test whether WireMock works fine or not .here it is

 @Test
    public  void testWireMock()
    {
        try {

            configureFor("localhost", 8084);
            stubFor(any(urlEqualTo("/v1/service1/local-dates/"))
                    .willReturn(aResponse().withStatus(200).withBody("hello wireMOck")));;
         
            String datesEndPoint = "https://dates-service-svc/v1/service1/local-dates/";
      HttpClient client = HttpClient.newBuilder()
                    .version(HttpClient.Version.HTTP_1_1)
                    .followRedirects(HttpClient.Redirect.NORMAL)
                    .connectTimeout(Duration.ofSeconds(20))
                    .build();
            URI uri = new URIBuilder(paymentDatesEndPoint)     
                    .build();
            HttpRequest request = HttpRequest.newBuilder()
                    .GET()
                    .uri(uri)
                    .build();
            HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
            List<ServeEvent> allServeEvents = getAllServeEvents();
            List<LoggedRequest> requests = findAll(getRequestedFor(urlMatching("/v1/.*")));
            verify(getRequestedFor(urlEqualTo("/v1/service1/local-dates/")));
        }
        catch (Exception e)
        {
            Assertions.fail(e);
//            System.out.println(e.getMessage());
        }
    }

I tried the solutions below:

  • The solution proposed by @P.Raber in this thread
  • I used WireMockServer instead of WireMockRule
  • I removed ConfigureFor() and put it again
  • I configured the wirkmock to start on the same port as the external local service runs (this would sound so dump but I am running out of solutions ) ; however this also made no difference . it still fails

  • Just a guess but your test is reaching out to dates-service-svc and your mock is listening on localhost? – Byron Oct 07 '21 at 13:21
  • yes , I think the mock is listening on the localwhereas the HTTP client is trying to send the request to actual data-service-svc . the request suppose to pass by the WireMock server and returned the mocked response , but this is not case – Omar Abo Elsoud Oct 07 '21 at 17:03
  • @Byron as I mentioned , I issued the request from the post man using *http://localhost:8084//__admin/{requestURL} and I received a reply from WireMock – Omar Abo Elsoud Oct 07 '21 at 17:11
