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
