This will give you the default timeout of 30 seconds for the command
run. As long as you are confident the selftests are going to stay under
this limit this is fine, however you'll probably want to make this
explicit :-)
Also you probably want something akin to this:
stdout, stderr, returncode = barebox.run('selftest')
assert returncode == 0, "selftest failed:\n {}\n".format("".join(stdout))
Which will output the selftest stdout if the selftest fails.
