Integration Test fails, /graphql enpoint not found

If i try to execute an integration test the graphql endpoint is not found, the test returns a “404”

RunWith(SpringRunner.class)
@SpringBootTest(
        webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
@EnableConfigurationProperties(GraphQLServletProperties.class)
@TestPropertySource(
        locations = "classpath:application-integrationtest.yaml")
public class GraphQlControllerTest {


    @Autowired
    private MockMvc mvc;


    @Test
    public void myTests() throws Exception {
        String request = "{\"query\": \"query{groups{id}}\", \"variables\": null}";
        ResultActions response = mvc.perform(post("/graphql").content(request).contentType(MediaType.APPLICATION_JSON));

        response.andExpect(status().isOk());
    }
}

output of the test is:

MockHttpServletRequest:
      HTTP Method = POST
      Request URI = /graphql
       Parameters = {}
          Headers = {Content-Type=[application/json;charset=UTF-8]}

Handler:
             Type = org.springframework.web.servlet.resource.ResourceHttpRequestHandler

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 404
    Error message = null
          Headers = {}
     Content type = null
             Body = 
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

java.lang.AssertionError: Status 
Expected :200
Actual   :404

has anyone an working example for writing integration tests?

I came to the conclusion that MockMvc is not supposed to be used for testing raw servlets, as here we are not exposing /graphql endpoint as a Spring MVC Controller, but rather as a raw HttpServlet.

The following works for me quite nicely:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebTestClient;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.web.reactive.server.WebTestClient;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient
public class AbstractGraphQLTest {

    @SpringBootApplication
    static class App {

    }

    @Autowired
    private WebTestClient webTestClient;

    @Autowired
    private ObjectMapper mapper;

    private String json(String query) throws JsonProcessingException {
        ObjectNode node = mapper.createObjectNode();
        node.put("query", query);
        return mapper.writeValueAsString(node);
    }

    protected WebTestClient.BodyContentSpec graphql(String query) throws JsonProcessingException {
        return webTestClient.post()
                .uri("/graphql")
                .bodyValue(json(query))
                .exchange()
                .expectBody();
    }

}

and then:

class default_handler extends AbstractGraphQLTest {

        @Test
        void expected_error__message_from_error() throws IOException {
            graphql("{illegalArgumentException}")
                    .jsonPath("errors[0].message").isEqualTo(EXPECTED_ERROR_MESSAGE)
                    .jsonPath("data.illegalArgumentException").doesNotExist();
        }
}

I also have problems with the test. I also get the error 404 in the GraphQLResult. The loading of the test query getAllRoutes.graphql works, that I have checked. I think the problem is that the application will not start up, because the spring beans will not be created. I have set a few breakpoints that are not called.

Here is the excerpt from my test.

@RunWith(SpringRunner.class)
@GraphQLTest
public class GraphQLRouteTest {

   @Autowired
    private GraphQLTestTemplate graphQLTestTemplate;

    @Test
    public void routes() throws IOException {
        GraphQLResponse response = graphQLTestTemplate.postForResource("getAllRoutes.graphql");
        assertNotNull(response);
        assertTrue(response.isOk());
        assertEquals("1", response.get("$.data.routes.id"));
    }

}
