Often times one is running a new test baseline we want to continue to
start testing where we left off if the last test was a crash. This is
in particular useful if you are doing automation and want to kick off
where the last test crashed.
To do this the first thing that occurred to me was to use the check.time
file as an expunge file but that doesn't work so well if you crashed
as the file turns out empty.
So instead add super simple argument --start-after which let's you
skip all tests inclusive of the test you specified, letting you pick up
where you last left off testing from a crash. This is intended to work
if you are not using a random order.
If the target test is not found in your test list we complain and
bail. This is not as obvious when you specify groups, so likewise
we do a special check when you use groups to ensure the test is at
least part of one group.
Demo:
root@demo-xfs-reflink /var/lib/xfstests # ./check -s xfs_reflink -n -g soak --start-after generic/025
Start after test generic/025 not found in any group specified.
Be sure you specify a test present in one of your test run groups if using --start-after.
Your set of groups have these tests:
generic/476 generic/521 generic/522 generic/616 generic/617 generic/642 generic/650
root@demo-xfs-reflink /var/lib/xfstests # ./check -s xfs_reflink -n -g soak --start-after generic/522

Changes since v2:
- Simplify to just one variable as requested by Zorro
- Remove the unused grep_start_after variable as pointed out by Andrey Albersht
- Make the conflict with randomize explicit, although we could support
it, it is just odd to use it with randomize...
- Replace the not-needed echo -e, with just echo
Changes since v1:
This all addresses Anand Jain's feedback.
- Skip tests completely which are not going to be run
- Sanity test to ensure the test is part of a group, if you listed
groups, and if not provide a useful output giving the list of all
tests in your group so you can know better which one is a valid test
to skip
- Sanity test to ensure the test you specified is valid
- Moves the trim during file processing now using a routine
