[PATCH v2 0/4] add tests to verify IFS (In Field Scan) driver functionality

by Pengfei Xu

To verify IFS (In Field Scan [1]) driver functionality, add the following 6 test cases: 1. Verify that IFS sysfs entries are created after loading the IFS module 2. Check if loading an invalid IFS test image fails and loading a valid one succeeds 3. Perform IFS scan test on each CPU using all the available image files 4. Perform IFS scan with first test image file on a random CPU for 3 rounds 5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU 6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.

by Muhammad Usama Anjum

Don't print that 88 sub-tests are going to be executed. But then skip. The error is printed that executed test was only 1 while 88 should have run: Old output: TAP version 13 1..88 ok 2 # SKIP all tests require euid == 0 # Planned tests != run tests (88 != 1) # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0 New and correct output: TAP version 13 1..0 # SKIP all tests require euid == 0 Signed-off-by: Muhammad Usama Anjum <usama.anjum(a)collabora.com> --- tools/testing/selftests/openat2/resolve_test.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/openat2/resolve_test.c b/tools/testing/selftests/openat2/resolve_test.c index bbafad440893c..5472ec478d227 100644 --- a/tools/testing/selftests/openat2/resolve_test.c +++ b/tools/testing/selftests/openat2/resolve_test.c @@ -508,12 +508,13 @@ void test_openat2_opath_tests(void) int main(int argc, char **argv) { ksft_print_header(); - ksft_set_plan(NUM_TESTS); /* NOTE: We should be checking for CAP_SYS_ADMIN here... */ - if (geteuid() != 0) + if (geteuid()) ksft_exit_skip("all tests require euid == 0\n"); + ksft_set_plan(NUM_TESTS); + test_openat2_opath_tests(); if (ksft_get_fail_cnt() + ksft_get_error_cnt() > 0) -- 2.39.2
