# Dockerfile for containerized game test client
# Used by E2E tests to run multiple game client instances
#
# Build: make build-test-client
# Usage: started by the test broker via Testcontainers (see tests/JunimoServer.Tests/Containers/GameClientContainer.cs)
#
# NOTE: This Dockerfile duplicates the game-downloader and smapi-builder stages of the main
# Dockerfile: the game DLLs build the test-client mod, and the SMAPI build is what a client
# installs into the shared game volume when it boots before the server.
