Cannot resolve reference to bean 'cacheManager'

Trying to run a unit test on a Controller in my Spring app.

My test class:

@RunWith (SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration ({"classpath*:WEB-INF/spring/application-context-config.xml", "data-source-test-config.xml", 
                        "classpath*:WEB-INF/spring/security-context-config.xml"})
public class PropsControllerTest 

The error I'm getting:

2015-04-03 23:22:51.729 WARN  AbstractApplicationContext:487 - Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0': Cannot resolve reference to bean 'cacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'cacheManager' is defined

My application-context-config.xml defines:

ehcache.xml Defines:

<ehcache>
    <cache name="backslap"
           maxBytesLocalHeap="256M"
           eternal="false"
           timeToLiveSeconds="3600"
           overflowToDisk="false"
           memoryStoreEvictionPolicy="LRU"/>
</ehcache>

I've got copies of ehcache.xml in three places: src/main/resources/, test/main/resources/ and in the directory of my test class. Nothing fixes this problem.

How do I make Spring find the file during testing (it has no problem finding the file when running)? Failing that, how do I make Spring stop wanting this information (the cache is utterly worthless during my tests), or at least let me just specify it in my application-context-config.xml file?

Thank you for any help.
