# =============================================================================
# Dockerfile.test — Test macbook_hardware_fixer.sh on Ubuntu 26.04
#
# Tests: package availability, config file generation, script logic, sysctl syntax
# Does NOT test: systemd services, kernel modules, hardware-specific paths
#
# Usage:
#   docker build -f Dockerfile.test -t macbook-test .
#   docker run --rm macbook-test
#
# Or via make:
#   make test-docker
