ApolloQueryCall Test in java

Question

I am trying to test onResponse method. If I understand korrectly, when I call apolloQueryCall.enqueue , it should return response as response. When I run this code, it does not enter neither onResponse or onFailere. What am I missing? I could not find examples that work for me on the internet for Java.

   String body = "{\n" +
            "    \"data\": {\n" +
            "        \"message\": \"kedi\"\n" +
            "    }\n" +
            "}";

    MockWebServer webServer = new MockWebServer();
    MockResponse response = new MockResponse().setResponseCode(200).setBody(body);
    webServer.enqueue(response);

    var apolloClient = ApolloClient.builder()
            .serverUrl(webServer.url("http://localhost/mock"))
            .okHttpClient(okHttpClient)
            .build();

    var apolloQueryCall = apolloClient.query(query);

    apolloQueryCall.enqueue(new ApolloCall.Callback<MyClass.Data>() {
        @Override
        public void onResponse(@NotNull Response<MyClass.Data> response) {
            System.out.println("response:" + response);
        }

        @Override
        public void onFailure(@NotNull ApolloException e) {
            System.out.println(e.getMessage());
        }
    });
    
    webServer.close();
