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 --no-isolation
  • because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
  • install .whl file in </install/prefix>
  • run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Use zope.testrunner to run the tests.

As at the monebt pytest is de facto standard pytest should be supported as well.
Just retested 2.4 and pytest is failing a bit different now

pytest is very popular, yes, but it's not what we use across the entire ZopeFoundation repository, and porting the test suite to work properly with pytest is a large job that nobody has volunteered to do so far.

Nevertheless currently testrunner is way behind of what pytest can do/provide.
Personnally currently I don't see to much sense to stick to testrunner as it barrely evolving (but this is only my personall opinion and I fully understand that someone may not agree). testrunner was born before pytest and currently it is quite big set of reasons why +95% of all modules are now tesable using pytest. With some additional modyfications I've reached even higher ratio

[tkloczko@devel-g2v SPECS]$ grep ^%pytest python-*spec -l | wc -l; ls -1 python-*.spec | wc -l
998
1025

But all that is a bit off topic.

In addition, many of the suites make important use of the
zope.testrunner feature (hierarchical) layer. This allows related tests
to share a common setup (set up once before those tests,
shared by the tests and torn down after them).
It is important because many tests have a very expensive
setup; sharing allows to reduce testing time.

(Note that zodbpickle doesn't use layers, so this is technically offtopic for this issue.)

pytest has session-level fixtures which run setup and teardown at most once during the test session. I'm not sure pytest orders tests by fixture use, so there are any test suites that rely on zope.testrunner layers to clean up any global monkey-patching before running the next test layer, that might not work after porting to pytest. Also, pytest has no direct support for running tests in a subprocess, which zope.testrunner uses to handle layers that raise NotImplementedError in the layer teardown. (You can use a plugin like pytest-xdist to run tests in a different process, but you won't get the automatic grouping by test layer.)

As I said, migration takes work. Even if a test suite runs under pytest, have you verified that it runs the same tests? Like here you're showing us a pytest run with 8 tests, but the actual zodbpickle test suite contains 427 tests. The reason most of them weren't picked up is that we're relying on zope.testrunner's feature where it calls test_suite in each test module to collect the tests, and we use that here to pick the right test file, depending on the major Python version.

Have you verified that the other packages where you chose to use pytest actually run all the tests? We rely on test_suite() quite often, e.g. to provide custom setUp/tearDown/globs to different doctest files.

It's all solvable, but solving it takes work.

And that is easy to explain because pyetst only scans for units test_.py files. and in src/zodbpickle/tests/ there are pickle.py so to allow pytest scan for more units some files needs to be renamed.
