from PyMultition import MultitionInstanceFactory


class Test:
    def __init__(self, attr):
        self.attr = attr


a = MultitionInstanceFactory.get_instance(Test, '1')
b = MultitionInstanceFactory.get_instance(Test, '2')
c = MultitionInstanceFactory.get_instance(Test, '2', multition_key='')
d = MultitionInstanceFactory.get_instance(Test, '2', multition_key='normal')
e = MultitionInstanceFactory.get_instance(Test, '2', multition_key='special')
f = MultitionInstanceFactory.get_instance(Test, '2', multition_key='special')

assert a is not b
assert b is c
assert c is not d
assert d is not e
assert e is f
