is this a bug of unit test?

[wangxiyuan (wangxiyuan)]

It looks like that the tests "glance.unit.api.test_cmd.TestGlanceApiCmd.test_unsupported_default_store broke" the test. You can comment out this test and try again.

[Wenjun Wang (wangwenjun)]

Yes,this can solve the problme.but some other failed tests exist,I will tip on the Bug Description.

[liwei (wei-li)]

I also encountered the same problem in glance.Is there any way to solve it？

[wangxiyuan (wangxiyuan)]

Sorry that i'm too busy to analyse it. Feel free to assign this bug to yourself.

[Abhishek Kekane (abhishek-kekane)]

Hi,

If you add below line in in test_unsupported_default_store after self.stubs.UnsetAll() then it will resolve this issue.

self.stubs.Set(glance.common.config, 'load_paste_app', self._do_nothing)

The cause of failure is self.stubs.UnsetAll() will unset all the configuration stubbed in setUp() method, however we still need to stub load_paste_app to avoid actual loading of the same.

[zhuangzejian (zhuangzejian)]

Kekane's method is absolutely useful.
Thanks you Kekane.

[Cyril Roelandt (cyril-roelandt)]

The tests work fine in the CI, and py27 is no longer supported. Closing this, feel free to reopen if you still hit this bug.
