Introduction

This package contains a unittest test class based on the one from the Mocker mock library (http://labix.org/mocker).

This class provides support for registering Zope 3 components (utilities, adapters, subscription adapters and event handlers) from mocks and tearing down the global component registry during test tear-down.

There are also a few convenience methods and parameter checkers that are useful to Zope and Plone testing.

Please see the Mocker documentation for more detail:

http://labix.org/mocker

See testcase.py for more detail on the mock helper methods.

A test case that mocks a utility may look like this:

from plone.mocktestcase import MockTestCase

from my.package.interfaces import IMyInterface
from my.package.foo import testable_method

class MyTestCase(MockTestCase):

    def test_something(self):

        utility_mock = self.mocker.mock()
        self.expect(utility_mock.do_something()).result("foo")
        self.mock_utility(utility_mock, IMyInterface)

        # Put mocker into replay mode
        self.replay()

        # Verify that testable_method() looks up a utility for
        # IMyInterface and calls do_something() on it, which returns
        # "foo".

        testable_method()
