Bug#1080277: FTBFS with setuptools >= 72: error: invalid command 'test'

[Stefano Rivera]

Source: pyemd
Version: 0.5.1.54.g802fa86-2
Severity: serious
Tags: ftbfs
Justification: FTBFS
User: debian-python at lists.debian.org
Usertags: setup.py-test

Dear maintainer,

During a test rebuild for packages affected by setuptools 72, pyemd
failed to rebuild.

FWIW: I think these bugs were all caused by setuptools v72 dropping
support for the "test" command, so dh-python has fallen back to
distutils / other test plugins.

If you're trying to figure out how to fix the bug, look at the
implementation of test_suite in setup.py to see what magic it does for
test setup.

About the archive rebuild: The build was made on debusine.debian.net,
using sbuild.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks,
