LTSI (long Term Support Initiative) is an ecosystem-wide collaborative project hosted at the Linux Foundation to create and maintain a common Linux base for the use in a variety of industrial products. And LTSI Test Framework is a Jenkins based test automation framework for LTSI kernels. I have many testing knowledge for embedded systems such as server system controller, storage system, network equipment, printer and IVI. And I will contribute to share and reduce the test effort on AGL kernels. This presentation will show testing knowledge for embedded systems, and this will also show how to use LTSI test framework.
