zope-testrunner not discovering any tests when working from sdist (pypi archive)

[apteryks]

What I did:

I unpack https://files.pythonhosted.org/packages/source/p/persistent/persistent-6.1.tar.gz, then run:

zope-testrunner

I also tried

zope-testrunner --test-path=tests

What I expect to happen:

All tests pass.

What actually happened:

No tests discovered:

Total: 0 tests, 0 failures, 0 errors and 0 skipped in 0.000 seconds.

What version of Python and Zope/Addons I am using:

Guix System (GNU/Linux), Python 3.10.7 and persistent 6.1 with the following inputs:

python-cffi@1.17.1 python-manuel@1.10.1 python-setuptools@75.6.0
+ python-zope-deferredimport@4.3.1 python-zope-interface@5.1.0 python-zope-testrunner@6.6

You want --test-path=src as well as --path=src. But by itself that won't work, you can't test persistent without it being built first. You can run python setup.py bdist_ext -i and that gets you part way, but (1) that's deprecated and (2) you'll still be missing test dependencies, so ideally you really need to install the package first along with its [test] extra. You seem to be manually managing test dependencies, though, so good luck!
