How do I get my Spring-JUnit test to think its running in a GenericApplicationContext?

Question

I’m using Spring 3.2.6.RELEASE, JUnit 4.11, and DWR 3.0.0-rc2. My question is, when running a Spring-JUnit integration test, how can I simulate things being run in a org.springframework.context.support.GenericApplicationContext?

I tried this:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml", "classpath:dwr-context.xml" })
@WebAppConfiguration
public class MyServiceIT 
{}

in which my “dwr-context.xml” file is set to be

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
       http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">

  <dwr:configuration>
    <dwr:convert class="java.lang.StackTraceElement" type="bean"/>
  </dwr:configuration>
  <dwr:annotation-config id="annotationConfig" />
  <dwr:annotation-scan base-package="org.mainco.subco" scanDataTransferObject="true" scanRemoteProxy="true" />
  <dwr:url-mapping />
  <dwr:controller id="dwrController" debug="false" /> 

  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="alwaysUseFullPath" value="true"/>
    <property name="urlMap">
      <map>
        <entry key="/dwr/**" value-ref="dwrController" />
      </map>
    </property>
  </bean> 
</beans>

However, all my JUnit tests ultimately die with the below exception:

(“java.lang.IllegalStateException: WebApplicationObjectSupport instance [org.directwebremoting.spring.DwrController@11297ba3] does not run in a WebApplicationContext but in: org.springframework.context.support.GenericApplicationContext@4e513d61”).

If I could figure out how to trick the system into running in a GenericApplicationContext I’d get past this issue.

I came across same error and fixed it adding @WebAppConfiguration in a Test class, as follows:

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import com.arpit.jsr.config.DataConfig;
import com.arpit.jsr.config.WebConfig;

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { WebConfig.class, DataConfig.class })
public class ServiceTest {

    @Test
    public void testSayHello() {
        Assert.assertEquals("Hello world!", "Hello world!");
    }
}
