Duplicate of #5831 which was closed in #5840 which was against 1.5.x so the next release off any branch will include this.

What are you packaging mpl for (given that you have hit both here an cycler in the last few days)?

Oops, I should remember to search in the closed issues as well :-)

I'm packaging a bunch of (Python) packages for Nix/NixOS. We basically have a function to a build a Python package, and by default tests are also automatically run with python setup.py test. In case the tests need to be called in a different way we override the default call.

That reminds me. I just accidentally happened to notice that tests had to be run like this. Nowadays, with the newer versions of setuptools, we basically always get an error when tests are not found, thereby halting the build. This is great for us, since that way we can be almost entirely sure that all packages are actually being tested in the correct way.

With matplotlib python setup.py test shows the message that tests have to be run as python tests.py and then exits gracefully. I think it would be better to raise an exception, just as if python setup.py test was not implemented, but then of course with this added message.

At the very least, it should probably exit with a non-zero exit code.

We did have support for python setup.py test but in the end it resulted in a series of new issues so we removed it again. I would be strongly against waisting any more time on that but making it raise an error seems like a good idea.

👍 to dying less cleanly and 👍 to not spending any more time getting python setup.py test to run now.

We might want to re-evaluate the second part if/when the move to py.test from nose gets merged.

Am I correct that from 2.0 the sdist won't include the tests?

the source dist should include all of the tests and baseline images.

Indeed, they are included, though not installed, which is fine. I was just checking how to run the tests now since we get ImportError: matplotlib test data is not installed. Can we run the tests with an installed copy, without installing the tests, by referring to the matplotlib source?

Yes, that should be possible. See s https://matplotlib.org/2.1.0/api/api_changes.html#default-install-no-longer-includes-test-images

[edited to point at stable link, thanks @kapsh ]

If somebody wants to read last link, it is https://matplotlib.org/2.1.0/api/api_changes.html#default-install-no-longer-includes-test-images to be precise.

Thanks @kapsh ! I should have used the stable link initially.

Hi , I have installed matplotlib 2.2.3, and i have enabled the flag " local_freetype=True" in setup.cfg.template . But still i am getting the error . Please check below for the error.
