Just normal build, install and test cycle used on building package from non-root account:

• "setup.py build"
• "setup.py install --root </install/prefix>"
• "pytest with PYTHONPATH pointing to setearch and sitelib inside </install/prefix>

So, you’re using pytest, but giving it an argument it doesn’t understand?

I haven’t used pytest. I use unittest because that’s what the re module uses:

py -3.8 -m unittest -v regex.test_regex

On first look it looks like pytest argument is passed to unittest and this is why it fails.

Temporary I’ve added that failing unit in my rpm spec fiels to list of deselected units so no ruch :slight_smile:

BTW you should not use “python -m unittest” beause module executed that way adds upfront to sys.path current directory and $PYTHONPATH will be used only if in curret directory will be no module. Result will be that it will be tested not what has been installed in </install/prefix> but source tree.

python -m unittest is shown in the “Command-Line Interface” section in the Python docs!

I’m talking about the Python docs on unittest, and the section titled “Command-Line Interface”.
