RestAssuredMockMvc Connection to http://localhost:8080 refused

Question

I developed a Spring MVC webapp with rest methods. I would love to use RestAssured to create JUnit test classes. From the documentation it looks really simple to do but I'm having some problem instead. Basically I want to use it to avoid a runtime Tomcat instance but the problem is that when I execute the JUnit test class I obtain the following exception:

org.apache.http.conn.HttpHostConnectException: Connection to http://localhost:8082 refused
...
Caused by: java.net.ConnectException: Connection refused

This is my JUnit class:

import static com.jayway.restassured.RestAssured.given;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.web.context.WebApplicationContext;

import com.jayway.restassured.module.mockmvc.RestAssuredMockMvc;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"file:src/test/resources/spring/application-test-config.xml"})
@WebAppConfiguration
public class ExternalControllerTest {
    private static final Logger logger = LoggerFactory.getLogger(ExternalControllerTest.class);

    @Autowired
    WebApplicationContext webApplicationContext;

    @Before
    public void setUp() throws Exception {
        RestAssuredMockMvc.webAppContextSetup(webApplicationContext);
    }

    @Test
    public void addClientDeviceId_Success() {

            given().get("/api/test").then().statusCode(200);

    }

}

I also tried to configure RestAssuredMockMvc directly with the controller class but the result is the same:

RestAssuredMockMvc.standaloneSetup(new ExternalController());

The controller looks like that:

@Controller
@RequestMapping("/api")
public class ExternalController {

    public ExternalController() {
        logger.info("ExternalController initialised!");
    }

    @RequestMapping(value="/test", method = RequestMethod.GET, produces={"application/json", "application/xml"})
    public @ResponseBody DmsResponse test(HttpServletResponse response) {
        response.setStatus(HttpServletResponse.SC_OK);
        return null;
    }

}

In this guide http://www.jayway.com/2014/01/14/unit-testing-spring-mvc-controllers-with-rest-assured/ is specified that "The most important aspect is that it’s simpler to get the environment started. You don’t need to bootstrap a container (for example Jetty or Tomcat), you simply initialize RestAssuredMockMvc with a context (for example a controller) and you’re ready to go." So I don't understand where the problem is. Any suggestion?

The war file deployed with Tomcat works fine. Thanks

You are statically importing the wrong methods. You're importing given from com.jayway.restassured.RestAssured (io.restassured.RestAssured if using version 3.x) but you should statically import the methods from com.jayway.restassured.module.mockmvc.RestAssuredMockMvc (io.restassured.module.mockmvc.RestAssuredMockMvc in version 3.x). Refer to the documentation for more info.
