Question

I’m trying to configure JUnit to work with Spring, but I cannot.

I create a test class this way:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/web-application-config.xml"})
public class MyControllerToTest {
        @Autowired
    private MyController ctr;

    @Test
    ....
}

In classpath, I inserted src/main/resources, where the web-application-config.xml is located. Here its content:

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.1.xsd">

<!-- Scans for application @Components to deploy -->
<context:component-scan base-package="com.infoone.mycontrollerpackage"/>

<!-- Imports the configurations of the different infrastructure systems of the application -->
<import resource="webflow-config.xml" />
<import resource="webmvc-config.xml" />
<import resource="data-access-config.xml" />
<import resource="repository-config.xml" />
<import resource="security-config.xml" />

When I run as JUnit the MyControllerToTest class, I get the following:

ERROR: org.springframework.test.context.TestContextManager - Caught exception while allowing TestExecutionListener
[org.springframework.test.context.support.DependencyInjectionTestExecutionListener@6419fa] to prepare test instance [com.infoone.myapp.MyControllerToTest@10036f2]

Thank you!

The Problem is that the WEB-INF folder is not (so easy) accessible while testing (with maven), because it is in an other location while testing.

I mean:

• when you run the tests, you run the compiled classes in folder: <project>/target/test-classes and the WEB-INF folder is located in <project>/target
• when you run the application the web-inf located in <war>/WEB-INF while your classes resists in <war>/WEB-INF/classes

What I want to say, the relative path to the resource in WEB-INF folder is different between test and application.

Anyway there is a spring project called spring-test-mvc, maybe you can use it or use some ideas you find in there code.
