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.

.. _plone.testlayers: http://github.com/witsch/plone.testlayers/

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)
