freezer.tests.unit.scheduler.test_coordination module

class freezer.tests.unit.scheduler.test_coordination.TestCoordinationFunctionalFileDriver(methodName='runTest')

Bases: TestCase

Functional tests against the local tooz file driver.

The file driver keeps membership and locks in a shared directory, so several coordinators in one process behave like real cluster members — membership, ring ownership and locks are exercised for real, without external services.
