What OpenTMI is

OpenTMI is open-source test management infrastructure for IoT and embedded testing. It keeps related software builds, test logs, test cases, and device-under-test resources together for analysis, with support for test case management, run tracking, and QA reporting. Its default web interface has a dashboard, lists for test cases and results, pivot and tree views, and a resource list. A REST JSON API and Socket.IO WebSockets connect the backend to Python and JavaScript clients; the JavaScript client works with Node.js and browsers. A pytest plugin can send results and metadata to an OpenTMI server and optionally store logs. Teams can extend the Node.js and MongoDB system with addons. The project is free and the core is under the MIT license. Deployment instructions cover Docker or installation from source with npm, with Node.js and MongoDB required. Clustered mode is documented for performance, restart behavior, updates without downtime, and more clients. HTTPS is supported, but self-signed certificates are not recommended for production. The default GUI README says GitHub login is not ready yet.

Who it suits

OpenTMI suits teams managing tests for IoT hardware and embedded systems, especially where devices or hardware configurations vary. It may fit teams that want linked test records, automation uploads, and API access in a self-hosted system.

What it does well

Free and open source under the MIT license
Links builds, logs, cases, and device resources
Provides REST JSON and Socket.IO interfaces
Includes Python, JavaScript, and pytest integrations
Documents Docker and npm source deployment

What to know first

Requires Node.js and MongoDB
GitHub login is not ready in the default GUI
Self-signed certificates are not recommended for production

Limits

The project requires Node.js and MongoDB, and deployment is self-hosted. The default GUI README says GitHub login is not ready yet; the project also cautions against self-signed certificates for production HTTPS.

Getting started

Install Node.js and MongoDB
Deploy with Docker or install from source using npm
Start the OpenTMI server
Connect through the web GUI, REST API, or WebSockets
Use Python or JavaScript clients, or configure the pytest plugin
Configure HTTPS with production-appropriate certificates

Verdict

OpenTMI brings test records, results, and device resources into one test management system, with client libraries and a pytest plugin for automation workflows. Teams should account for its Node.js and MongoDB prerequisites and the default GUI's unfinished GitHub login.
