Introduction to Twister and Adding Support for Hardware Runners

Learn about Twister, Zephyr RTOS's automated test runner framework, and discover how to extend it with custom hardware runner support in this technical conference talk. Explore Twister's core functionality including test case identification, configuration and build processes, hardware execution, and result aggregation mechanisms. Dive deep into the framework's integration capabilities with hardware debugging tools, specifically examining XSDB (Xilinx System Debugger) for FPGA-based systems. Master the development of custom runners through detailed coverage of integration techniques and execution flow patterns. Gain practical insights into automating testing pipelines across target platforms, from simulators to physical hardware, while understanding how Twister discovers, builds, executes, and reports test results in embedded development environments.
