# test_mysqlx_soak_behavioral-t — TAP wrapper for the
# behavioral_validation.py harness (issues #5677, #5678).
#
# Runs inside the test-runner container of the docker-isolated TAP
# harness. Expects the proxysql.${INFRA_ID} container to be up with
# the mysqlx plugin loaded (via the mysqlx-soak group's setup-infras
# hook) and a route 'r1' bound to port 6603, plus a user 'alice' with
# password 'alicepass' provisioned.
#
# This wrapper emits exactly two TAP assertions:
#   1. the SIGTERM-mid-traffic scenario from behavioral_validation.py
#   2. the LOAD MYSQLX ROUTES TO RUNTIME mid-traffic scenario
# Each assertion is "ok" if behavioral_validation.py exited 0 for that
# scenario. The Python script's own internal asserts produce
# diagnostic # comments visible in the TAP output.
