[Xen-devel] [OSSTEST PATCH 06/11] ts-livepatch: Initial test-cases.



From: Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>

There are 37 of the test-cases in there. Before we run
any of them we verify that the payload files are present
in /usr/lib/debug.

If so we go through all of the test-cases.

v1: Initial submission.
v2: Add ts-livepatch-install
    Rename ts-livepatch to ts-livepatch-run
    Use target_cmd_root_status instead of target_cmd_root_rc
    Use target_cmd_output_status as well
    Remove tabs, replace with spaces
    Use Perl for string matching :-)
    Use subroutines for more complex string testing
    Use proper style for variable
v4: Expect the livepath output in DESTDIR/usr/lib/debug/xen-livepatch
     rather than directly in DESTDIR/usr/lib/debug.
    Very minor style changes.
