|
|
|
|
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 serverExplicitReady() is called just before
|
|
the blocking call (such as in setting up a client/server

connection and performing the accept() in setUp().
