The program test_progs have some very useful ability to specify a list of test name substrings for selecting which tests to run. This patch add the ability to list the selected test names without running them. This is practical for seeing which tests gets selected with given select arguments (which can also contain a exclude list via --name-blacklist). This output can also be used by shell-scripts in a for-loop: for N in $(./test_progs --list -t xdp); do \ ./test_progs -t $N 2>&1 > result_test_${N}.log & \ done ; wait This features can also be used for looking up a test number and returning a testname. If the selection was empty then a shell EXIT_FAILURE is returned. This is useful for scripting. e.g. like this: n=1; while [ $(./test_progs --list -n $n) ] ; do \ ./test_progs -n $n ; n=$(( n+1 )); \ done Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> --- tools/testing/selftests/bpf/test_progs.c | 18 ++++++++++++++++++ tools/testing/selftests/bpf/test_progs.h | 1 + 2 files changed, 19 insertions(+)
