Description Randy Barlow 2013-07-26 10:32:31 EDT
If you have the 2.2 branch checked out for Pulp platform, and the master branch checked out for pulp_rpm, running the unit tests on the platform will cause this error:

ERROR: test_init_calls_entry_points (server.test_plugin_api.TestAPI)
Traceback (most recent call last):

    from pulp.plugins.model import ApplicabilityReport
ImportError: cannot import name ApplicabilityReport

The platform unit tests should not be using the real entry points for its tests, as it can lead to these sorts of issues with broken test isolation. This also raises the question about whether this test will test anything if there are no entry points installed on the system.
