Nit: Why do you ASSERT_TRUE() the |policy_manager| but not the
|profile_connector| and |policy_service|?

Nit: As above: Should this method ASSERT_TRUE() to be on the safe side?

[pneubeck (no reviews), 2015/06/16 09:16:21]

I removed the asserts above, as I don't think that this really helps.
The tests will fail anyways. With test isolation the impact should be small. In
the worst case, one has to make a debug build to find out where it crashes.
