17377	Test admin_views.UserAdminTest.test_user_permission_performance depends on side effects	Gregor Müllegger	nobody	"The test {{{admin_views.UserAdminTest.test_user_permission_performance}}} fails if it's run on its own. If run in conjunction with other tests, it gets a cache hit for looking up a content type. When run on it's own it needs to look that up, causing more queries than expected.
