def test_set_of_sets_reprs(self):
|
|
# This test creates a complex arrangement of frozensets and
|
|
# compares the pretty-printed repr against a string hard-coded in
|
|
# the test. The hard-coded repr depends on the sort order of
|
|
# frozensets.
|
|
#
|
|
# However, as the docs point out: "Since sets only define
|
|
# partial ordering (subset relationships), the output of the
|
|
# list.sort() method is undefined for lists of sets."
|
|
#
|
|
# In a nutshell, the test assumes frozenset({0}) will always
|
|
# sort before frozenset({1}), but:
|
|
#
|
|
# >>> frozenset({0}) < frozenset({1})
|
|
# False
|
|
# >>> frozenset({1}) < frozenset({0})
|
|
# False
|
|
#
|
|
# Consequently, this test is fragile and
|
|
# implementation-dependent. Small changes to Python's sort
|
|
# algorithm cause the test to fail when it should pass.
|
|
# XXX Or changes to the dictionary implementation...
