Hello.
Today I want to show you simple test configuration in spring mvc project.
In example I use java based configuration(I admit that this kind of configuration I prefer).
But in future I want to present xml based configuration, too.

On the bottom of the post you find link to github repository with full project.

Class under testing:

package com.raphaelsolarski.springtestconfig.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class MyController {

    @RequestMapping(path = "/", method = RequestMethod.GET)
    String home() {
        return "home";
    }

}

Test:

package com.raphaelsolarski.springtestconfig.controller;

import com.raphaelsolarski.springtestconfig.config.WebConfig;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.web.AnnotationConfigWebContextLoader;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebConfig.class}, loader = AnnotationConfigWebContextLoader.class)
@TestExecutionListeners(listeners = {DependencyInjectionTestExecutionListener.class})
@WebAppConfiguration
public class MyControllerTest {

    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void getRootShouldReturnHomeView() throws Exception {
        mockMvc.perform(get("/")).andExpect(MockMvcResultMatchers.view().name("home"));
    }

}
