Use a factory function:
_instance = None
def createFoo(parameters):
if _instance is None:
_instance = Foo(parameters)
return _instance
and replace all occurrences of Foo(parameters) with createFoo(parameters).
For new-style classes, you may override the __new__ method instead.
Perhaps I didn't understand your problem correctly because this is
unrelated to unit testing...
