This fixture is basically an alternative to the synchronized decorator with
the external flag so that tearDowns and addCleanups will be included in
the lock context for locking between tests. The fixture is recommended to
be the first line in a test method, like so::
If you run this:
python -m openstack.common.lockutils python setup.py testr <etc>
def test_method(self):
self.useFixture(LockFixture)
...
or the first line in setUp if all the test methods in the class are
required to be serialized. Something like::
class TestCase(testtools.testcase):
def setUp(self):
self.useFixture(LockFixture)
super(TestCase, self).setUp()
...
This is because addCleanups are put on a LIFO queue that gets run after the
test method exits. (either by completing or raising an exception)
a temporary directory will be created for all your locks and passed to all
your tests in an environment variable. The temporary dir will be deleted
afterwards and the return value will be preserved.
