Description of problem:
Running
from xarray.tests.test_dataset import create_test_data
fails with:
 missing pytest if only python3-xarray has been installed

Once python3-pytest is installed, the error is the following:

ImportError while importing test module '/builddir/build/BUILD/xbout-0.3.4/xbout/tests/test_plot.py'.
Hint: make sure your test modules/packages have valid Python names.

How reproducible:
always

Steps to Reproduce:
1. python3 -c "import xarray.tests.test_dataset"

Alternatively try to build python-xbout 0.3.4 for rawhide:
https://koji.fedoraproject.org/koji/taskinfo?taskID=95936268

Actual results:
An ImportError is raised. Presumably that is due to a change in pandas.

Expected results:
Import works
