[Matplotlib-devel] tests+baseline images no longer installed by default
Folks (particularly down-stream packagers),
As of https://github.com/matplotlib/matplotlib/pull/7757 (which is currently on master and I am in the process of backporting for 2.0) the test images are not installed by default. We already are stripping the test images from the official wheels and conda-forge packages. This change greatly reduces the resultant file size :
To restore installing the tests and images have a `setup.cfg` with
tests = True
toolkit_tests = True
in the source directory at build / install time.
A consequence of this change is that by default `pip install ./` or `setup.py install` will not install the tests (and hence `python run_tests.py` will not work). We suggest using `pip install -v -e ./` or using a `setup.cfg` file.
