| |
| The ThreadableTest class makes it easy to create a threaded |

| new threaded class from an existing unit test, use multiple |
| inheritance: |
| |
| class NewClass (OldClass, ThreadableTest): |
| pass |
| |
| This class defines two new fixture functions with obvious |
| purposes for overriding: |
| |
| clientSetUp () |
| clientTearDown () |
| |
| Any new test functions within the class must then define |
| tests in pairs, where the test name is preceeded with a |
| '_' to indicate the client portion of the test. Ex: |
| |
| def testFoo(self): |
| # Server portion |
| |
| def _testFoo(self): |
| # Client portion |
| |
| Any exceptions raised by the clients during their tests |
| are caught and transferred to the main thread to alert |
| the testing framework. |
| |
| Note, the server setup function cannot call any blocking |
| functions that rely on the client thread during setup, |
