.. _Test-TestReactorMixin: TestReactorMixin ++++++++++++++++ .. py:class:: buildbot.test.reactor.TestReactorMixin The class ``TestReactorMixin`` is used to create a fake ``twisted.internet.reactor`` in tests. This allows to mock the flow of time in tests. The fake reactor becomes available as ``self.reactor`` in the test case that mixes in ``TestReactorMixin``. Call ``self.reactor.advance(seconds)`` to advance the mocked time by the specified number of seconds. Call ``self.reactor.pump(seconds_list)`` to advance the mocked time multiple times as if by calling ``advance``. For more information see the documentation of `twisted.internet.task.Clock `_. .. py:method:: setup_test_reactor(use_asyncio=False) :param bool use_asyncio Whether to enable asyncio integration. Call this function in the ``setUp()`` of the test case to setup fake reactor.
