Phoenix Integration Tester

A Phoenix server used as the integration test target for PhoenixSharp, a C# Phoenix Channels client library.

The server is deployed publicly so that PhoenixSharp's integration tests can run against it. It exposes a WebSocket endpoint and a health-check REST endpoint covering the key scenarios: channel join with auth, message reply/push/error/timeout, and presence tracking.

Running Locally

mix setup
mix phx.server

Server starts at localhost:4000.

Running with Docker

docker compose up --build

API Surface

• WebSocket: /socket — accepts connections, routes tester:* topics
• Channel join: requires {"auth": "<value>"} in the payload
• Channel events: reply_test, push_test, error_test, timeout_test
• Presence: tracks users with device metadata on join
• Health check: GET /api/health-check returns {"ok": true}

Running Tests
