# BEGIN usage message

usage="Usage: $0 [--root] [--rootless] [FILENAME-PATTERN[:TEST-PATTERN]]...

$0 is a wrapper for invoking podman system tests.

   --root         Run only as root
   --rootless     Run only as user (i.e. you)
   --remote       Run with podman-remote

   FILENAME-PATTERN Run only test files that match 'test/system/*name*',
                    e.g. '500' or 'net' will match 500-networking.bats.

   TEST-PATTERN     When appended to a filename-pattern, and you have a
                    modern-enough version of bats installed (i.e. Fedora
                    but not RHEL), runs with '--filter TEST-PATTERN' which
                    runs only subtests within FILENAME-PATTERH whose names
                    match that string.

   --tag=TAG      Passed on to bats as '--filter-tags TAG'
                  As of 2025-09-01 the only tag used is 'ci:parallel'

   -t, --tap      Passed on to bats, which will format output in TAP format

   -T             Passed on to bats, which will then show timing data

   --help         display usage message

By default, tests ./bin/podman. To test a different podman, do:

    \$ env PODMAN=/abs/path/to/podman $0 ....

Examples:

    \$ $0 220:\"restart cleans up\"
       ... only the \"restart cleans up\" test in 220-healthcheck.bats

    \$ $0 --root 160:\"ps -f\"
       ... runs all tests in 160-volumes.bats that match \"ps -f\" (root only)
"
