Probably attached patch will fix this issue. But this patch doesn't
cover other similar problematic codes.
It seems this is multi inheritance problem. Following code shows B.setUp
and B.tearDown are called twice respectively. (In this issue, B
represents PyPIRCCommandTestCase)
class A(object): # LoggingSilencer
def setUp(self):
print "A setup"
super(A, self).setUp()
def tearDown(self):
print "A tearDown"
super(A, self).tearDown()
class B: # PyPIRCCommandTestCase
def setUp(self):
print "B setup"
def tearDown(self):
print "B tearDown"
class C(A, B): # sdistTestCase
def setUp(self):
A.setUp(self)
B.setUp(self)
def tearDown(self):
A.tearDown(self)
B.tearDown(self)
c = C()
c.setUp()
c.tearDown()
"""
A setup
B setup
B setup # called twice
A tearDown
B tearDown
B tearDown # ditto
"""
P.S. This is first time I saw the behavior of super in multi
inheritance. Movement of code flaw is interesting and fresh for me. :-)
