At the Embedded Open Source Summit 2024 in Seattle, Luis Ubieda demonstrated how Test-Driven Development (TDD) can transform Zephyr RTOS application development. This hands-on presentation shows developers how to overcome the complexities of applying TDD to embedded systems, particularly when dealing with Zephyr’s Device Trees, Kconfigs, and hardware dependencies.
Presentation Highlights
- TDD Fundamentals: Understanding the red-green-refactor cycle and its benefits for embedded development
- Zephyr-Specific Techniques: Practical approaches to mocking Device Tree nodes and complex subsystems
- Live Coding Demo: Building a motion detection engine using TDD methodology from scratch
- Faster Bug Detection: How TDD reduces time between bug injection and discovery from days to minutes
- Testing Frameworks: Overview of Ztest, FFF, Twister, and other tools available in Zephyr
