# Demo of the card API against a running simulator: purchase a card, activate
# it, look it up, check its balance and transactions, ask for the status of the
# purchase, place a card order and check it, lock the card, and try to lock it
# again.
#
# Only active endpoints are used (14 are active, see the README). The others answer 404.
# Not shown: 4.2, 4.6, 4.8, 4.13 and 4.14; the tests show them.
#
#   mix run --no-halt     # in another terminal
#   bash demo.sh          # set YSP_SIM_PORT if the simulator isn't on 4180
#
# Each step prints the request (without the msgHdr) and the response, and a
# table of all the steps is printed at the end.
#
# Resets the simulator first, so it can be run any number of times.
