Commit Message

Alex Bennée March 8, 2025, 9:52 p.m. UTC 
In preparation for handling more tests split out the common machine
setup details from the test specific stuff and add a helper for
launching the weston test. Instead of searching for "vkmark score" we
set a custom PS1 and wait for a successful completion. This ensures we
capture the score in the console log which otherwise wouldn't log
anything.
