Failed to Load ApplicationContext during Spring unit test

Question

I am trying to run a Junit functional test using Springs java-config for my application context. I am not sure if it is a problem with Spring or Junit... just not sure.. The application runs fine on my local server (hitting the db), but when I try to run my test it bombs out. I just moved from xml to java config so I can always import my xml context files (which I know works in my tests) but going forward I would rather just use my java config.

My Test Class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class,
        classes = { AppConfig.class, ServletConfig.class })
@EnvironmentConfiguration(db2Enabled = true)
public class EventDAOTest {

So it appears that it is not finding the configuration framework, but I have been following the reference guides and API... not sure what I am missing or not configuring correctly. I am using Spring 4.0, Junit 4.10

Also, for each test it throws this error. That to me means it is trying to load the ApplicationContext again (prepareRefresh)... once for each @Test -- that also doesn't make sense to me...

Here are some resources:

• ContextConfiguration API
• Spring Reference Guide
• Spring blog post

Answer 1

I moved from spring 3.2.0 to 4.0.3 and had to update my javax.servlet dependency (in maven) from servlet 2.5 to servlet 3.0.1. The final dependency was

       <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.0.1</version>
       </dependency>

Then it worked

Answer 2

You'll need to annotate your test class with

@WebAppConfiguration

so that the test environment provides your WebApplicationContext with a mock ServletContext required by your MVC configuration.

Answer 3

Since a couple people mentioned Servlet version issues:

As of Spring 4.0 the set of mocks is now based on the Servlet 3.0 API.

You have two options:

1. use 3.2.x spring-test dependency

    <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-test</artifactId>
       <version>3.2.14.RELEASE</version>
       <scope>test</scope>
    </dependency>

2. upgrade to servlet 3.0

    <dependency>
       <groupId>javax.servlet</groupId>
       <artifactId>javax.servlet-api</artifactId>
       <version>3.0.1</version>
    </dependency>

Answer 4

In gradle

testCompile 'javax.servlet:javax.servlet-api:3.1.0'

Note: this works for me even though I'm testing against Google App Engine (servlet 2.4) Because it is only used for tests.

https://jira.spring.io/browse/SPR-11049

Answer 5

the way to solve such problems - try to force import of the notFoundClass manually, by smth like: Class c = javax.servlet.SessionCookieConfig.class;

so Idea+Maven suggested me to add maven dependency, i agreed. And suddenly in pom.xml the code appeared:

    <dependency>
        <groupId>org.apache.geronimo.specs</groupId>
        <artifactId>geronimo-servlet_3.0_spec</artifactId>
        <version>1.0</version>
        <scope>test</scope>
    </dependency>

then i removed "Class c = javax.servlet.SessionCookieConfig.class;" - there is no need in it, rather than to load necessary dependency.

Answer 6

You can add a MockServletContext to your test applicationContext. The MockServletContext can be found in spring-test.jar (or maven dependency). You should (obviously) not use this in production, but only register it in a context that you include in your test context.

Answer 7

Use @ActiveProfiles({"{test", "default"}) annotation
