# Docker-based test runner for https_dns_proxy
# This script builds a test image and runs all tests in a proper Linux environment.
# Uses Docker's default bridge network which has NAT/masquerading properly configured
# for source address binding to work with external DNS servers.
#
# When to use:
# - Full regression testing before commits/PRs
# - CI/CD pipelines
# - Developing on macOS (proxy uses Linux-specific syscalls like accept4, MSG_MORE)
#
# Runtime: ~2-3 minutes
