Automated Testing for Arm-Based Systems With LAVA
This course introduces the Linaro Automated Validation Architecture (LAVA), covering how users write and submit jobs for automated testing on real hardware, how to analyze test results with queries and charts, and how administrators can install, configure, and manage a LAVA lab infrastructure.
Description
This course covers user and administrative topics. The first part introduces LAVA's role as a CI component for testing software on real hardware, explaining its architecture (server-dispatcher model), core components, and the process of writing and submitting LAVA jobs, which involves defining deploy, boot, and test actions. The second part delves into advanced usage, focusing on exploring test data, analyzing test results, creating queries and charts to track trends over time, integrating various test frameworks, and interfacing with LAVA via XML-RPC and the REST API, alongside advanced concepts like Multi-Node test jobs and power measurement. The final, optional session targets administrators, detailing the setup and maintenance of a LAVA lab, including different lab layouts, the purpose of services like the scheduler and dispatcher, and tasks such as adding users, workers, and devices.
