# Pretend the bank reported an incoming transfer, so a dev order can be paid
|
|
# without a bank.
|
|
#
|
|
# The transfer rail settles an order when a credit quoting its reference shows
|
|
# up in the credits file. In production that file is filled by
|
|
# `catcrafts-server --pull-credits` reading the real account; here it is filled
|
|
# by hand. Same file, same format, same matching code — which is the point:
|
|
# this exercises the real settlement path rather than a test double.
|
|
#
|
|
# tools/dev-credit.sh <orders-file> <reference> <amount-in-cents> [method]
|
|
#
|
|
# Example, paying order CC-2B6457 the €570.43 it is waiting for:
|
|
# tools/dev-credit.sh /tmp/dev/orders.jsonl CC-2B6457 57043
|
|
#
|
|
# The reference is matched forgivingly (case, spacing and punctuation are
|
|
# ignored, and the RF… form works too), so it is worth deliberately mangling it
|
|
# to watch that hold:
|
|
# tools/dev-credit.sh /tmp/dev/orders.jsonl "betaling cc 2b6457 bedankt" 57043
