# This script uses 'curl' to POST various ill-formed requests to the
# taler-exchange-httpd.  Basically, the goal is to make sure that the
# HTTP server survives (and produces the 'correct' error code).
#
# We read the JSON snippets from afl-tests/
#
# The afl-tests are generated as follows:
# 1) Capture all TCP traffic from 'test-auditor.sh'
# 2) Use 'tcpflow -e http -r $PCAP -o $OUTPUT' to get the HTTP streams
# 3) Remove HTTP streams unrelated to the exchange as well as the replies
# 4) Remove duplicated streams (check file size!)
# 5) Compile the exchange with AFL instrumentation
# 6) Run afl-fuzz -i $OUTPUT/ -o afl-tests/ ~/bin/taler-exchange-httpd \
#     -c test_taler_exchange_httpd.conf -t 1 -f @@
