@wkirdp please add two test in test_views.WorkspaceListByTypeTest to check that the appropriate template is being used:

• the default template is used when the default adapter is used
• the custom template is used when a custom adapter is used

For the second test, you can look at some other tests to see how to register a new adapter in a test.
