Mockserver cannot connect to any port

Question

Im using a mockserver to test api requests.

The mockserver wont start.

This is my code

@SpringBootTest
class RestApiMetaDataApplicationTests {
    private ClientAndServer mockServer;

    @BeforeClass
    public void startServer() throws Exception {
        mockServer = startClientAndServer(1080);
    }
 
    @AfterClass 
    public void stopServer() { 
        mockServer.stop();
        
    }
    
  
    @Test
    public void shouldReturnTrack() throws Exception {
        String isrc = "TEST1234560000";
        String responseBody = "{\"id\": \"1234\",\"name\": \"Some new track!\",\"duration_ms\": 12000000}";

        new MockServerClient("localhost", 1080)
            .when(
                request()
                    .withMethod("GET")
                    .withPath("/codechallenge/createTrack/" + isrc)
            )
            .respond(
            response()
                .withStatusCode(200)
                .withBody(responseBody)
                .withHeader("Content-Type", "application/json")
        );

    HttpClient httpClient = HttpClient.newHttpClient();
    HttpRequest httpRequest = HttpRequest.newBuilder()
        .GET()
        .uri(URI.create("http://localhost:1080/codechallenge/createTrack/" + isrc))
        .header("Content-Type", "application/json")
        .build();
    HttpResponse<String> httpResponse = httpClient.send(httpRequest, HttpResponse.BodyHandlers.ofString());
    String response = httpResponse.body();

    assertEquals(responseBody, response);
    assertEquals(200, httpResponse.statusCode());
}}

There is nothing running on port 1080 and I have tried other ports and none of them work.

I have found this thread on Github of other people encountering the same issue but none of the solutions offered have worked for me

The dependencies I am using are

        <dependency>
        <groupId>org.mock-server</groupId>
        <artifactId>mockserver-netty</artifactId>
        <version>5.11.2</version>
    </dependency>
    <dependency>
        <groupId>org.mock-server</groupId>
        <artifactId>mockserver-client-java</artifactId>
        <version>5.11.2</version>
        <scope>test</scope>
    </dependency>

This is some of the stacktrace

added plugin import for mockserver

<plugin>
            <groupId>org.mock-server</groupId>

            <version>3.10.8</version>

        </plugin>

can you show your plugin import for mock server? and its configurations? — Mohammed Fataka, Apr 09 '23 at 18:18
add how do you run mockServer? what is the command do you use for testing ? e.g `mvn mockserver:run` is command to run mock server! are you using it? — Mohammed Fataka, Apr 09 '23 at 18:35
I dont run a command, I just run the junit test, that builds and runs the spring project and runs the junit and immedity fails because it cant connect — Brendan Ahern, Apr 09 '23 at 18:39

the reason it is failing is you do not start the mock server and upon test, it will fail because there is nothing started at that port, I'm assuming you want it to automatically start server before the test, thus there are two options:

first: configure test task to be dependent of moctserver:run task second: when running test task before running a test task run a mock server.

check official docs for more info

Mockserver cannot connect to any port
