# Test Infrastructure
This document describes the local Docker-based test infrastructure for ScadaLink development. Seven services provide the external dependencies needed to run and test the system locally. The first seven run in `infra/docker-compose.yml`; Traefik runs alongside the cluster nodes in `docker/docker-compose.yml`.
