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::

||||
|
||||
def test_method(self):
|
||||
self.useFixture(LockFixture)
|

...
|

|
||||

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)
