Description Miro Hrončok 2019-03-29 18:14:37 UTC 
There are test failures with Python 3.8 and they block the bootstrap of Python 3.8 in Fedora. pytest was also updated to 4.3, but Python 2.7 tests pass, so that is not a probable cause:

That is python-pytest-mock-1.10.1-1.fc31.
Comment 1 Miro Hrončok 2019-03-29 18:26:43 UTC 
Upgrading to 1.10.2 does NOT help.
Comment 2 Miro Hrončok 2019-03-31 00:38:36 UTC 
Fixed upstream in 1.10.3

https://github.com/pytest-dev/pytest-mock/pull/140
Comment 3 Miro Hrončok 2019-04-04 17:15:14 UTC 
https://src.fedoraproject.org/rpms/python-pytest-mock/pull-request/1
Comment 4 Miro Hrončok 2019-07-13 16:32:51 UTC 
1.10.4 fails again: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/build/971242/
Comment 5 Julien Enselme 2019-07-13 16:56:39 UTC 
Are you sure? From your link, it seems it worked.
Comment 6 Miro Hrončok 2019-07-14 13:12:30 UTC 
That link shows "failed". I've tried again to be sure: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/build/971268/ again "failed"

The failure is on Python 2 however (weird):
