Test Infrastructure

This document describes the local Docker-based test infrastructure for ScadaBridge 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.

Traefik LB	traefik:v3.4	9000 (proxy), 8180 (dashboard)	docker/traefik/	docker/

Quick Start

cd infra
docker compose up -d

After the first startup, run the SQL setup and seed scripts:

docker exec -i scadabridge-mssql /opt/mssql-tools18/bin/sqlcmd \
  -S localhost -U sa -P 'ScadaBridge_Dev1#' -C \
  -i /docker-entrypoint-initdb.d/setup.sql

docker exec -i scadabridge-mssql /opt/mssql-tools18/bin/sqlcmd \
  -S localhost -U sa -P 'ScadaBridge_Dev1#' -C \
  -i /docker-entrypoint-initdb.d/machinedata_seed.sql

Per-Service Documentation

Each service has a dedicated document with configuration details, verification steps, and troubleshooting:

• test_infra_opcua.md — OPC UA test server (Azure IoT OPC PLC)
• test_infra_ldap.md — LDAP test server (GLAuth)
• test_infra_db.md — MS SQL 2022 database
• test_infra_smtp.md — SMTP test server (Mailpit)
• test_infra_restapi.md — REST API test server (Flask)
• test_infra_playwright.md — Playwright browser server (Central UI testing)
• Traefik LB — see docker/README.md and docker/traefik/ (runs with the cluster, not in infra/)

Remote Test Infrastructure

In addition to the local Docker services, the following remote services are available for testing against real AVEVA System Platform hardware.

Primary/backup testing: The dual OPC UA test servers (ports 50000 and 50010) in local Docker provide primary/backup endpoint pairs for testing Data Connection Layer failover. Use docker compose stop opcua to simulate primary failure and verify automatic failover to the backup.

Alarms & Conditions (native alarms): The infra OPC PLC server does expose OPC UA Alarms & Conditions — a ConditionRefresh against its event notifier replays the active condition set and a SnapshotComplete, so the native alarm mirror (IAlarmSubscribableConnection → NativeAlarmActor) can be exercised live. The OpcUaAlarmLiveSmokeTests.SubscribeAlarms_DeliversConditionRefreshSnapshot [SkippableFact] (Trait RequiresOpcUa) round-trips against opc.tcp://localhost:50000 and asserts the snapshot arrives; it reports Skipped (not failed) when the server is unreachable or — on a substitute server that lacks A&C — when no snapshot arrives within the window. The MxAccess Gateway alarm feed (MxGateway protocol) requires a live gateway and is verified via the docker-env2 manual deploy check, not in CI.

Connection Strings

For use in appsettings.Development.json:

{
  "ConnectionStrings": {
    "ScadaBridgeConfig": "Server=localhost,1433;Database=ScadaBridgeConfig;User Id=scadabridge_app;Password=ScadaBridge_Dev1#;TrustServerCertificate=true",
    "ScadaBridgeMachineData": "Server=localhost,1433;Database=ScadaBridgeMachineData;User Id=scadabridge_app;Password=ScadaBridge_Dev1#;TrustServerCertificate=true"
  },
  "Ldap": {
    "Server": "localhost",
    "Port": 3893,
    "BaseDN": "dc=zb,dc=local",
    "UseSsl": false
  },
  "OpcUa": {
    "EndpointUrl": "opc.tcp://localhost:50000"
  },
  "OpcUa2": {
    "EndpointUrl": "opc.tcp://localhost:50010"
  },
  "Smtp": {
    "Server": "localhost",
    "Port": 1025,
    "AuthMode": "None",
    "FromAddress": "scada-notifications@company.com",
    "ConnectionTimeout": 30
  },
  "ExternalSystems": {
    "TestApi": {
      "BaseUrl": "http://localhost:5200",
      "AuthMode": "ApiKey",
      "ApiKey": "scadabridge-test-key-1"
    }
  }
}

Stopping & Teardown

cd infra
docker compose down            # stop containers, preserve SQL data volume
docker compose stop opcua      # stop a single service (also: opcua2, ldap, mssql, smtp, restapi)

Full teardown (removes volumes, optionally images and venv):

cd infra
./teardown.sh              # stop containers + delete SQL data volume
./teardown.sh --images     # also remove downloaded Docker images
./teardown.sh --all        # also remove the Python venv

After a full teardown, the next docker compose up -d starts fresh — re-run the SQL setup script.
