Elamutest

Elamutest is a lightweight, open‑source testing framework designed primarily for embedded systems programming. Developed in the late 2010s by a small consortium of embedded software engineers, it aims to provide a uniform testing methodology for firmware written in C, C++, and Rust. The framework is distributed under the MIT license and is available on major code‑hosting platforms such as GitHub and GitLab.

The core of Elamutest is its platform‑agnostic test harness, which separates test definition from execution. Tests are written as standard unit tests using a minimal API; each test can be compiled into a host‑side executable or directly into a firmware binary for in‑chip execution. Elamutest supports deterministic random number generation, mock interfaces, and automatic test case discovery via annotations. When run on target hardware, the framework can report results over serial, TCP/IP, or through dedicated debug ports.

Key features include a built‑in assertion library, failure trace logging, and a small footprint that keeps the binary size to a few kilobytes. It also offers integration with continuous‑integration tools such as Travis CI, GitHub Actions, and Azure Pipelines. Because of its emphasis on modularity, developers can add custom checkers or plug in hardware‑specific drivers without modifying the core library.

The community around Elamutest is active on discussion forums and issue trackers, with regular releases that add support for new microcontroller families and improve language bindings. Documentation is hosted on readthedocs.org, and presence in embedded‑software conferences has helped spread its adoption among hobbyists and professional teams alike.
