 # One Big Target for services to register their unit test sources. This exists
 # to avoid having to maintain a separate test binary for every service.
 #
 # To add tests for a new service, please define a "tests" source_set in the
 # service subdirectory and add it as a dependency here. If your unit tests
 # use the ServiceTest framework, you must also include corresponding catalog
 # entries in the "service_unittests_catalog" target below.

Can this not just be a public_deps in //services/device:tests? Is this some
weird deficiency in our dependency system for Java targets? It's unfortunate
that you have to make any changes to this target's deps when you're not making
any other direct changes to the target.

     # NOTE: We do not currently support standalone service binaries on Android,
     # so any tests which use the ServiceTest framework to connect to standalone
     # services must be added here.
