Unable to register FHIR client

I have been trying to register a client since the upgrade from version 7.0.1 x to 7.0.2x.
I am trying to run a unit test. This is what I get back.
AuthorizationControllerTest.php (4.1 KB)

I was able to get past the missing class by including the _rest_config.php file in the AuthorizationController.php. However, that means it is broken somewhere else. My limited troubleshooting skills keep me from figuring out where.

Is there someone in the community that can help?
