pytest-plone

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

This package is built on top of zope.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:

Fixtures

generate_mo

Add a new fixture to your conftest.py to force generate_mo to be called for all tests.

@pytest.fixture(scope="session", autouse=True)
def session_initialization(generate_mo):
    """Fixture used to force translation files to be compiled."""
    yield

app

def test_app(app):
    """Test portal title."""
    assert app.getPhysicalPath() == ("", )

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

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

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

    from myproduct.interfaces import IMyProductLayer

    assert IMyProductLayer in browser_layers

controlpanel_actions

def test_configlet_install(controlpanel_actions):

    assert "myproductcontrolpanel" in controlpanel_actions

get_fti

def test_get_fti(get_fti):
    """Test if Document fti is installed."""
    assert get_fti("Document") is not None

get_behaviors

import pytest

def test_has_behavior(self, get_behaviors, behavior):
    assert behavior in get_behaviors("Document")

get_vocabulary

from zope.schema.vocabulary import SimpleVocabulary

VOCAB = "plone.app.vocabularies.AvailableContentLanguages"

def test_get_vocabulary(get_vocabulary):
    """Test plone.app.vocabularies.AvailableContentLanguages."""
    vocab = get_vocabulary(VOCAB)
    assert vocab is not None
    assert isinstance(vocab, SimpleVocabulary)

setup_tool

def test_setup_tool(setup_tool):

    profile = f"{PACKAGE_NAME}:default"
    version = profile_last_version(profile)
    assert version == "1000"

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 install

To run tests for this package:

make test

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