Issues getting service (Externalizer) in unit tests

[Alex Theys]

Hi,

I am having trouble with getting an AEM specific service from inside a unit test class.
I have tried using the context.getService() method as well as using the service reference with the bundle context.

I'd like to get Externalizer and inject it into the xlass I am testing, however it always resolves as null:
Code:
Externalizer service = context.getService(Externalizer.class);

Or code:
ServiceReference ref = context.bundleContext().getServiceReference(Externalizer.class.getName());
Externalizer service2 = (Externalizer) context.bundleContext().getService(ref);

Am I doing something wrong or misunderstanding the steps to retrieve an OSGI service?

Cheers,
Alex

I should add that I'll have to use the same process for HtmlLibraryManager

hello alex.

please note that AEM mock implements only a tiny subset of the AEM API out of the box (but the most important parts).
the features that are supported are described here: http://wcm.io/testing/aem-mock/

in your case (code using Externalizer or HtmlLibraryManager) it is the easiest solution to create a dynamic mock yourself e.g. using Mockito, and register it to the OSGi context in the unit test:

context.registerService(Externalizer.class, mockExternalizer);

then you can define the expected behavior of the mocked externalizer and validate calls to its methods.

Hi Stefan,

I see, I thought it might be the case, I wanted to be sure.

Cheers,

Thanks for the quick reply!

btw., if you think it would be useful to have direct support for those OSGi services in AEM mocks we can add them.
please crate a JIRA issue in this case.
patches are welcome as well...
