"""Tool for running test groups against different ChromeOS boards and platforms.

run_tests allows users to execute test groups against Autotest hosts. Will
create Autotest jobs given a board, platform, and list of test groups. Test
groups are configurable via a JSON configuration file.

run_tests will create jobs using a specialized control file which will update
the targeted hosts to a specific board type and build version before running
jobs against them.
