#
# IMPORTANT NOTE
#
# We use "isnt exception {...}, undef, ..." a lot which is REALLY BAD
# practice. This should only ever be done in provider tests since we cannot
# be sure what exception message a provider returns and we do NOT mandate
# specific messages so we can only test if something died.
#
# When writing new provider tests please always test first with a "like /qr/"
# instead and then once the tests are all working against one provider switch
# them to the bad "isnt undef" style so they are portable.
