I detected some fixture changes in commit 1ef91803e8c3886b39113d78c82831df2bad3387

The local fixture instance_without_name is used in the following files:

• cfme/tests/cloud/test_providers.py
  • test_add_provider_with_instance_without_name

Please, consider creating a PRT run to make sure your fixture changes do not break existing usage :smiley:

@kedark3 @john-dupuy @mshriver So I would like to make this PR merged. The problem is that create_vm by default doesn't handle vm without name. I tried to use _create_vm(), but it didn't work as wrapanapi had no identificator for vm - by default it's name, but when instance doesn't have name it's identified by uuid, but _create_vm doesn't provide one. As I am leaving by the end of this month I would like to make this PR merged without using create_vm. I could try to fix the issue, but it would take me probably a lot of time and I don't see the point to use create_vm as it's premise is AFAIK that every VM created by this method has test assignee as a suffix in its name, which cannot be applied for this specific test. Thanks for feedback.
