Spring MVC Junit Test ApplicationContext Config

Question

I think I should be using the same application context config files with Junit test! is that correct?

The issue that I have, I can run my spring mvc app without an issue, and I am trying to add a new junit test to test one of the controller and I can't even run the test. obviously the application context files are not the issue, as the app is running perfectly fine. So the question is how can I run a junit test using the existing application context config files? any link or example would be appreciated.

Currently my application context files are located in /src/main/webapp/WEB-INF/*-appContext.xml

In my web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/*-appContext.xml
    </param-value>
</context-param>

I have no problem to run the app but I can't run the test.

java.lang.IllegalStateException: Failed to load ApplicationContext

    at org.springframework.test.context.web.ServletTestExecutionListener.setUpRequestContextIfNecessary(ServletTestExecutionListener.java:105) 

In the testing class;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("file:src/main/webapp/WEB-INF/mvc-appContext.xml")
public class AppTests {
    private MockMvc mockMvc;

also I have tried using "*"

file:src/main/webapp/WEB-INF/*-appContext.xml

and tried using multiple files

@ContextConfiguration(locations = {
        "file:src/main/webapp/WEB-INF/mvc-appContext.xml",
        "file:src/main/webapp/WEB-INF/mongo-appContext.xml"}) 

and tried using single xml to import others

<import resource="file:src/main/webapp/WEB-INF/mvc-appContext.xml"/>
<import resource="file:src/main/webapp/WEB-INF/mongo-appContext.xml"/>

but none of them work for junit testing! so where should I put the config files?

It doesn't seem to initialize other beans!

Answer 1

Create separate resource folder for testsuit. Set it in classpath.
You can load it like below.

@ContextConfiguration(locations = {"classpath:applicationContext.xml"})

Answer 2

Here is how I configured my tests:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextHierarchy({
    @ContextConfiguration(classes = MyAppConfig.class),
    @ContextConfiguration(locations = "file:src/main/webapp/WEB-INF/jsp-controller.xml"),
    @ContextConfiguration("file:src/main/webapp/WEB-INF/rest-controller.xml")})

public class TestController {

    @Autowired
    private WebApplicationContext wac;
    private MockMvc mockMvc;

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

In my case I had a third listing "MyAppConfig" (annotations). I included, just so you have an example. In your case you can remove @ContextConfiguration(classes = MyAppConfig.class),

Edit the above to include you specific files.

Hope that helps.
