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


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:

Fixtures

portal

def test_portal_title(portal):
    """Test portal title."""
    assert portal.title == "Plone Site"

http_request

from plone import api


def test_myproduct_controlpanel_view(portal, http_request):
    """Test myproduct_controlpanel browser view is available."""
    view = api.content.get_view(
        "myproduct-controlpanel", portal, http_request
    )
    assert view is not None

installer

import pytest


PACKAGE_NAME = "myproduct"


@pytest.fixture
def uninstall(installer):
    """Fixture to uninstall a package."""
    installer.uninstall_product(PACKAGE_NAME)


def test_product_installed(installer):
    """Test if myproduct is installed."""
    assert installer.is_product_installed(PACKAGE_NAME) is True

@pytest.mark.parametrize(
    "package",
    [
        "collective.casestudy",
        "pytest-plone",
    ]
)
def test_dependency_installed(installer, package):
    """Test if dependency is installed."""
    assert installer.is_product_installed(package) is True

browser_layers

def test_browserlayer(browser_layers):
    """Test that IMyProductLayer is registered."""
    from myproduct.interfaces import IMyProductLayer


    assert IMyProductLayer in browser_layers

controlpanel_actions

def test_configlet_install(controlpanel_actions):
    """Test if control panel is installed."""
    assert "myproductcontrolpanel" in controlpanel_actions

Plugin Development

You need a working python environment (system, virtualenv, pyenv, etc) version 3.8 or superior.

Then install the dependencies and a development instance using:

make build

To run tests for this package:

make test

By default we use the latest Plone version in the 6.x series.
