'''
Python 2.[67] port of Python 3.4's test_ipaddress.
Almost verbatim copy of core lib w/compatibility fixes
'''
# pylint: skip-file
# List of compatibility changes:
# This backport uses bytearray instead of bytes, as bytes is the same
# as str in Python 2.7.
#bytes = bytearray
# s/\(b'[^']\+'\)/bytearray(\1)/g
# plus manual fixes for implicit string concatenation.
# Python 3.4 has assertRaisesRegex where Python 2.7 only has assertRaisesRegexp.
# s/\.assertRaisesRegexp(/.assertRaisesRegexp(/
# Python 2.6 carries assertRaisesRegexp and others in unittest2
# Python 2.6 wants unicode into bytes.fromhex
# s/bytes.fromhex\("/bytes.fromhex(u"/g
# Further compatibility changes are marked "Compatibility", below.

# One big change in ipaddress over the original ipaddr module is
# error reporting that tries to assume users *don't know the rules*
# for what constitutes an RFC compliant IP address
# Ensuring these errors are emitted correctly in all relevant cases
# meant moving to a more systematic test structure that allows the
# test structure to map more directly to the module structure
# Note that if the constructors are refactored so that addresses with
# multiple problems get classified differently, that's OK - just
# move the affected examples to the newly appropriate test case.
# There is some duplication between the original relatively ad hoc
# test suite and the new systematic tests. While some redundancy in
# testing is considered preferable to accidentally deleting a valid
# test, the original test suite will likely be reduced over time as
# redundant tests are identified.
