    text
    copied!<p>I am trying to get Spring to inject EasyMock mocks in my unit tests.</p> <p>In my applicationContext.xml, I have this:</p> <pre><code>&lt;bean id="mockService" class="org.easymock.EasyMock" factory-method="createMock" name="MockService"&gt; &lt;constructor-arg index="0" value="my.project.Service"/&gt; &lt;/bean&gt; </code></pre> <p>In my unit test I have this:</p> <pre><code>@Autowired @Qualifier("mockService") private Service service; public void testGetFoo() { Foo foo = new Foo(); expect(service.findFoo()).andReturn(foo); replay(service); // &lt;-- This is line 45, which causes the exception // Assertions go here... } </code></pre> <p>When I try to run my test, I get this stack trace:</p> <pre><code>java.lang.ClassCastException: org.springframework.aop.framework.JdkDynamicAopProxy at org.easymock.EasyMock.getControl(EasyMock.java:1330) at org.easymock.EasyMock.replay(EasyMock.java:1279) at TestFooBar.testGetFoo(TestVodServiceLocator.java:45) </code></pre> <p>I am quite new to both Spring and EasyMock, but it seems to me that the error is caused by EasyMock trying to call a method on what it assumes to be an instance of EasyMock, but is in reality a dynamic proxy created by Spring. As I understand it, dynamic proxies only implement the methods defined in the interface, in this case the interface for Service.</p> <p>What I don't understand is that <a href="http://javadevelopmentforthemasses.blogspot.com/2008/07/mocking-spring-tests.html" rel="nofollow noreferrer">from what I read</a> (also <a href="http://satukubik.com/2007/12/21/spring-tips-initializing-bean-using-easymock-for-unit-test/" rel="nofollow noreferrer">here</a>), what I'm trying to achieve at least seems to be possible.</p> <p>So my question is: What I'm I not doing or what am I doing wrong?</p>
