Painless setup of Plone integration test layers

Project description

Introduction

plone.testlayers is supposed to make setting up test layers for Plone integration tests quick and painless. It’s main function, makeTestLayer will conveniently generate a test layer, which will load your packages ZCML and install them, apply a GenericSetup profile and help you set up sample content for speedier testing.

Usage

To make use of plone.testlayers you’d typically create a base test case for your package, somewhat like:

from Products.PloneTestCase import PloneTestCase as ptc
from plone.testlayers import makeTestLayer

def create(portal):
    """ create sample content for test runs """
    portal.invokeFactory('File', 'foo', title='foo', file='foo bar')

def destroy(portal):
    """ clean up sample content for test runs """
    portal.manage_delObjects(ids='foo')

ptc.setupPloneSite()
FooLayer = makeTestLayer(packages=('collective.foo', 'collective.bar'),
    profile='collective.foo:default', create=create, destroy=destroy)

class FooTestCase(ptc.PloneTestCase):
    """ base class for integration tests """
    layer = FooLayer

With that in place you can now set up your individual test cases like:

from unittest import defaultTestLoader
from collective.foo.tests.base import FooTestCase

class FooTests(FooTestCase):

    def testFoo(self):
        # the 'foo' object set up in the layer should already exist
        self.failUnless(self.portal['foo'])

def test_suite():
    return defaultTestLoader.loadTestsFromName(__name__)
