Ease adding new features aka plug-ins

[icemac]

Currently there seems to be no easy way to create additional features for the testrunner in packages outside zope.testrunner. See Shoobx/shoobx.junitxml as an example of such a plug-in. (Its README what is currently needed to integrate it in zope.testrunner. But this is only one half of what has to be done: The code has to be called before executing the configuration phase of zope.testrunner. So having it in a module of the package under test is too late.)

Pytest uses setuptools entry points for the discovery of plug-ins, see https://docs.pytest.org/en/latest/writing_plugins.html#setuptools-entry-points
Maybe this could be an idea here, too.

collective.xmltestreport is another one that extends zope.testrunner to add JUnit xml output.

(Digression: zope.testrunner should support that natively.)

The biggest problem, as usual, is lack of volunteers who are willing to contribute features to zope.testrunner and then maintain them.

@strichter Are you interested in such a plug-in system for an easier integration of shoobx.junitxml into zope.testrunner?

It currently only supports Python 2 and it replaces zope.testrunner doe to the lack of extensibility

I found your issue on Launchpad.net https://bugs.launchpad.net/zope.testrunner/+bug/691365 😄
