Testing and quality assurance in Zephyr RTOS - Meetup
2026-05-07 16:15 - 19:30
Zephyr RTOS is an open source operating system in the embedded world and is increasingly used in both industrial products and IoT devices. In this event, we will take a closer look at how to work systematically with testing and quality in Zephyr-based projects.
The lecture will, among other things, introduce Zephyr’s test frameworks, including ztest for unit tests and Twister for automated test execution.
Develco will demonstrate how to use hardware-in-the-loop testing, where Twister builds firmware, flashes it to a physical target and executes tests directly on the hardware. For this purpose, some hardware will be used, specifically for testing. Practical examples will be based on concrete Zephyr code and show how to structure test cases and automate validation of embedded functionality. Mjølner will share a real-life example of rapid product development with Zephyr, where Test-Driven Development is the driving force under unclear and constantly changing requirements.
There will be two 30-45 minute technical presentations – one hosted by Develco and one by Mjølner Informatics. There will be time for questions and networking with pizza afterwards. Henrik Brix Andersen, who sits on the Zephyr Technical Steering Committee and Architecture Working Group, will be present during the event and will be happy to take questions.
Target group
Embedded developers, firmware engineers and technically interested people who work with or want to work with Zephyr RTOS and modern testing methods in embedded systems.
Prerequisites
A certain technical level is a good prerequisite for this event, but everyone with an interest in embedded software and modern development tools is welcome. If you have specific issues or test scenarios you would like to have covered, please contact the organizer before the lecture.
Outcome
Participants will receive a practical introduction to Zephyr’s testing tools and an understanding of how to establish automated tests, both in software and directly on hardware, as a direct part of the development process.
