# 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.
