pytest-plone 0.2.0

Pytest plugin to test Plone addons

pytest-plone

pytest-plone is a pytest plugin providing fixtures and helpers to test Plone add-ons.

This package is built on top of gocept.pytestlayer.

Reasoning

Despite the fact Plone, and Zope, have their codebases tested with unittest, over the years pytest became the most popular choice for testing in Python.

pytest is more flexible and easier to use than unittest and has a rich ecosystem of plugins that you can use to extend its functionality.

Warning

THIS PACKAGE IS NOT CONSIDERED TO BE STABLE AND FIXTURES COULD CHANGE BEFORE A FINAL RELEASE

Usage

In your top-level conftest.py import your testing layers, and also import fixtures_factory -- which will accept a iterator of tuples containing the testing layer and a prefix to be used to generate the needed pytest fixtures.

from Products.CMFPlone.testing import PRODUCTS_CMFPLONE_FUNCTIONAL_TESTING
from Products.CMFPlone.testing import PRODUCTS_CMFPLONE_INTEGRATION_TESTING
from pytest_plone import fixtures_factory


pytest_plugins = ["pytest_plone"]


globals().update(
    fixtures_factory(
        (
            (PRODUCTS_CMFPLONE_FUNCTIONAL_TESTING, "functional"),
            (PRODUCTS_CMFPLONE_INTEGRATION_TESTING, "integration"),
        )
    )
)

In the code above, the following pytest fixtures will be available to your tests:

functional_session	Session
functional_class	Class
