Failed to load ApplicationContext for JUnit test of Spring controller

I want to write a test case to check my controller (getPersons). This is a server side code. I have confusion what should i put inside @ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/app-contest.xml"})

Secondly, I'm getting some errors like this:

Failed to load application context. Can not find the path [which I specified in @ContextConfiguration]

I have a structure like this:

 restAPI
    *src/main/java
      com.company.controller
         personController.java
    *Test
      com.company.testController
         personControllerTest.java
    *src
      main
       webapp
         WEBINF
           app-context.xml


@Autowired
private PersonService personService;

@RequestMapping(value="/t2/{yy_id}/person", method=RequestMethod.GET)
@ResponseBody
public PersonInfo[] getPersons() {

    return personService.getPersons();
}

This is my Test

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:WEB-INF/app-context.xml"})
@WebAppConfiguration
public class PersonControllerTest  {


@Autowired
private WebApplicationContext wac;

private MockMvc mockMvc;

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

@Autowired
private PersonService personService;

@Test
public void getPersons() throws Exception {

    this.mockMvc.perform(get("/t2/1/person")
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());

}

I was facing this issue after migrating to Junit 5 from Junit4.

For me this resolved the issue -

@TestPropertySource(properties = { "spring.config.location=classpath:application-test.yml" })

in

@SpringBootTest
@TestPropertySource(properties = { "spring.config.location=classpath:application-test.yml" })
class ApplicationTests {

    @Test
    void contextLoads() {
        assertTrue(true);
    }

}

where application-test.yml is located under src/test/resources

you also need to add this to @ActiveProfiles("test") all your test classes since I am using test profile (application-test.yml).

Sovled by editing the annotation

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

Try this with Junit5:

@SpringBootTest(classes = {ServletWebServerFactoryAutoConfiguration.class},
        webEnvironment = RANDOM_PORT,
        properties = {"spring.cloud.config.enabled=false"})
@ExtendWith(MockitoExtension.class)
@AutoConfigureMockMvc

In case you landed here based on the title, desperate for a solution and happen to be using Junit 5 Jupiter, you need to use

@ExtendWith(SpringExtension.class)

instead of

@RunWith(SpringJUnit4ClassRunner.class)

As mentioned in the discussion: WEB-INF is not really part of the class path. If you use a common template, such as maven, use src/main/resources or src/test/resources to place the app-context.xml in. Then you can use classpath:.

Place your config file in src/main/resources/app-context.xml and use the following code:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
  ...
}

You can also create your test context with different configurations of beans.

Place your config file into src/test/resources/test-app-context.xml and use:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
  ...
}

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

Solved by adding the following dependency into pom.xml file : 

<dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>test</scope>
</dependency>

If you are using Maven, add the below config in your pom.xml:

<build>
    <testResources>
                <testResource>
                    <directory>src/main/webapp</directory>
                </testResource>
    </testResources>
</build>

With this config, you will be able to access xml files in WEB-INF folder. From Maven POM Reference: The testResources element block contains testResource elements. Their definitions are similar to resource elements, but are naturally used during test phases.
