Jython is an implementation of the high-level, dynamic, object-oriented
language Python written in 100% Pure Java, and seamlessly integrated with
the Java platform. It thus allows you to run Python on any Java platform.

"""Threadable Test class
The ThreadableTest class makes it easy to create a threaded
client/server pair from an existing unit test. To create a
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,
unless serverExplicityReady() is called just before
the blocking call (such as in setting up a client/server
connection and performing the accept() in setUp().
