How to register a Mocked ApplicationListener

[Proner]

Hi,

I'm trying to unit test a service that sends ApplicationEvent.
So I want to mock (with easyMock) an ApplicationListener.

I test the MockFactory proposed by Ronen [1] but the well created instance of my ApplicationListener is not registered in the ApplicationContext.

For instance, my MockApplicationListenerFactory

public class MockApplicationListenerFactory implements FactoryBean, InitializingBean {
	
	private ApplicationListener applicationListener;
	
	private Class<ApplicationListener> type;
	
	public void afterPropertiesSet() {
		this.applicationListener = EasyMock.createMock(type);
	}
		
	public void setType(final Class<ApplicationListener> type) {
		this.type = type;
	}

	@Override
	public Object getObject() throws Exception {
		return this.applicationListener;
	}

	@Override
	public Class<ApplicationListener> getObjectType() {
		return ApplicationListener.class;
	}

	@Override
	public boolean isSingleton() {
		return true;
	}

}

And the test context

<bean id="reportListener" class="my.test.MockApplicationListenerFactory">
		<property name="type" value="org.springframework.context.ApplicationListener" />
	</bean>

Am I missing something for register the listener in applicationContext ?

After some debugging time on spring-2.5.6, I came to the conclusion of a lack of the ApplicationContext which is not able to register an ApplicationListener via bean factory.

I plan to open an issue if someone is able to confirm that point.

However, it is of course possible that I miss something, so please let me know

It is strange that object produced by factory bean is not registered as application listeners, but it is possible to add it programmatically:

        ApplicationEventMulticaster applicationEventMulticaster = (ApplicationEventMulticaster) applicationContext.getBean("applicationEventMulticaster");
        applicationEventMulticaster.addApplicationListener((ApplicationListener) applicationContext.getBean("reportListener"));

    <bean id="applicationEventMulticaster" class="org.springframework.context.event.SimpleApplicationEventMulticaster" />

    <bean id="reportListener" class="com.example.MocksFactory">
        <property name="type" value="org.springframework.context.ApplicationListener" />
    </bean>

Thanks a lot Andrei,

I register programmatically my Mock Listener and I'm now able to verify the different event send by my service. It's a cool stuff that Easy Mock. It disappointing me a lot, but I'm on the way to love it.
