How to test a spring controller method by using MockMvc?

问题

I\'m using spring 3.2.0 and junit 4

This is my controller method which I need to test

@RequestMapping(value=\"Home\")
public ModelAndView returnHome(){

return new ModelAndView(\"Home\");    
}

spring-servlet config is:

<context:annotation-config/>
    <context:component-scan base-package=\"com.spring.poc\" />
    <mvc:annotation-driven /> 

    <bean id=\"jspViewResolver\"
    class=\"org.springframework.web.servlet.view.InternalResourceViewResolver\">
    <property name=\"viewClass\"
        value=\"org.springframework.web.servlet.view.JstlView\" />
    <property name=\"prefix\" value=\"/WEB-INF/jsp/\" />
    <property name=\"suffix\" value=\".jsp\" />

This is my test class :

public class TestController {

private MockMvc mockMvc;

@Before
public void setup() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setPrefix(\"/WEB-INF/\");
    viewResolver.setSuffix(\".jsp\");
    this.mockMvc = standaloneSetup(new CController()).setViewResolvers(
            viewResolver).build();
}

@Test
public void CControllerTest() throws Exception {
    ......
    ......      
}

}

How can I test this method with MockMvc ?

You can use your applications dispatcher servlet xml using the following annoations. The following example is hitting a controller with the path /mysessiontest setting some session attributes and expecting a certain view to be returned:

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration({ "classpath:springDispatcher-servlet.xml" })

public class MySessionControllerTest {

    @Autowired WebApplicationContext wac; 
    @Autowired MockHttpSession session;
    @Autowired MockHttpServletRequest request;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void getAccount() throws Exception {
        UserDomain user = new UserDomain();
        user.setFirstName("johnny");

        session.setAttribute("sessionParm",user);
        this.mockMvc.perform(get("/mysessiontest").session(session)
        .accept(MediaType.TEXT_HTML))
        .andExpect(status().isOk())
        .andExpect(view().name("test"));
    }
}
