LAVA is a python framework for testing software on hardware which accepts test jobs to perform on selected hardware to provide a black box to continuous integration tests. LAVA development and deployment is fully open, using git, gerrit, wiki, IRC & mailing lists. The majority of hardware is hosted at the lab in Cambridge, UK and includes around one hundred devices including panda, beaglebone-black and arndale boards as well as calxeda servers. Jobs can be run on multiple nodes using a variety of test environments - the main requirement is that the device has a serial connection which is usable for the entirety of the test.
