@reference in Unit Tests

Hello, hopefully the last question this week.

I inject my Service in the servlet with:

@Reference
IRssFeed rssFeed;

The question is now how to do it with AEM Context.

@Test
public void testDoGetForJson() throws IOException, WCMException {

context.registerService(IRssFeed.class, new RssFeedImpl());

}

I also tried the other ways, but the rssFeed is always null.

// register OSGi service

context.registerService(MyClass.class, myService);

// or alternatively: inject dependencies, activate and register OSGi service

context.registerInjectActivateService(myService);

At first step I added the maven-build plugin to my pom.xml but afterwards i get some errors for old testcases:

This is one example of the errors appeared after adding the plugin:

if I use this:

IRssFeed rssFeed = new RssFeedImpl();
MockOsgi.injectServices(rssFeed, bundleContext);
MockOsgi.activate(rssFeed,bundleContext);

The error message change to:

org.apache.sling.testing.mock.osgi.NoScrMetadataException: No OSGi SCR metadata found for class com.test.aem.relaunch.services.rss.RssFeedImpl

I thought the maven plugin will create it for me?

So is there any other way to inject the reference? Or someone sees a mistake?

Yes I know it works, but the question is how to inject the Reference during unit tests?

@Test
public void testDoGetForJson() throws IOException, WCMException {

IRssFeed rssFeed = new RssFeedImpl();
   context.registerInjectActivateService(rssFeed);
   context.requestPathInfo().setSelectorString("rss");
   context.requestPathInfo().setExtension("xml");
   context.currentPage("/content/de/ueber-uns/presse/press-releases");
   rssFeedServlet.doGet(context.request(), context.response());

}

Then I get this error:

org.apache.sling.testing.mock.osgi.NoScrMetadataException: No OSGi SCR metadata found for class
