#!/bin/bash
# Run QtTesting XML test files against the Cockatrice build.
#
# Usage:
#   ./Testing/run_test.sh [--visual] [--all | <test-file.xml> ...]
#
# Options:
#   --visual    Run with native display (shows the GUI window).
#               Default is headless (QT_QPA_PLATFORM=offscreen).
#   --all       Run every *.xml file in Testing/.
#
# Environment:
#   COCKATRICE_BIN   Path to the client binary (default: build/debug/cockatrice/cockatrice,
#                    or the .app bundle binary on macOS).
#   TEST_TIMEOUT     Seconds a single test may run before it is killed (default: 180).
#                    Uses timeout, or gtimeout from coreutils on macOS.
#
# Requires the debug build to exist at build/debug/cockatrice/cockatrice.
