1.8.0: pytest is failing

[kloczek]

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

First just run pytest:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-pytest-steps-1.8.0-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-pytest-steps-1.8.0-2.fc35.x86_64/usr/lib/python3.8/site-packages

Because pytest_steps.tests is not installed I've been trying to preload it using --pyargs:

Your last message is simply due to conda not being installed. However for the first message, this is a structure problem as in pytest-cases, I'll have to adopt the src/tests separation as in pytest-cases.
I'll let you know

[kloczek]

If may I ask .. for what is used conda in those tests? 🤔
I still have no packaged conda so I'm trying to asses impact of skipping those test.

Thx.

[smarie]

conda is used to ensure reproducible multi-python-version builds in all my python repositories. Historically (a few years back) it was the only system able to get reliable builds across platforms (windows, etc.), especially when compiled wheels where needed.

I still use it for this reason and the convenience, although more and more packages (e.g. pandas) now publish pre-compiled wheels for major platforms so conda is less and less mandatory.

During build rpm packag I need to be sure that test suite execution result will deliver result against exat version of the python usied during build process.
I know that maybe I'm asking for to much but maybe it would be good to move such tests one layer above plan test suite execution because in such scenarios like mine the test suite would be always kind of useless/producing false results? 🤔

[smarie]

it would be to move such tests one layer above plan test suite execution

what do you mean ?

I plan to do with this repo the same as in pytest-cases (you know, the clean separation between src and tests) so that running pytest should work for you.

That will solve pytest

In this case pytest i scanning source tree but is loading modul;es from $PYTHONPATH.
Because pytest_steps.tests is not isntalled pytest cannot find it.

[kloczek]

gentle ping .. any update 😋

[smarie]

Probably during summer I will do this one and pytest-harvest. A bit hard to find time :(
If you have the possibility to propose a PR following the one I did in pytest-cases (https://github.com/smarie/python-pytest-cases/pull/232/files) do not hesitate to go for it!

[kloczek]

Any update? 🤔

[kloczek]

One more thing: you need to remove use pytest-runner becauae it is already deprecated.
Look on "Deprecation Notice" on https://github.com/pytest-dev/pytest-runner/
This module will be archived soon.

[smarie]

Thanks @kloczek ! Still no time to work on this on my side currently I'm afraid. Since it does not prevent users to use it it goes into lower priority than other issues on other libs :( But I still hope to get it done

[kloczek]

Any update? 🤔
