It's not your fault but I think we need to defer this until KUnit gains support of the run statistics. My guts telling me if we allow more and more conversions like this the point will vanish and nobody will care. I like the code, but I can give my tag after KUnit prints some kind of this: * This is how the current output looks like in success: test_uuid: all 18 tests passed * And when it fails: test_uuid: failed 18 out of 18 tests > Changes from v1: > - Test suite name: uuid_test -> uuid > - Config name: TEST_UUID -> UUID_KUNIT_TEST > - Config entry in the Kconfig file left where it is > - Converted tests to use _MSG variant > > André Almeida (1): > lib: Convert UUID runtime test to KUnit > > lib/Kconfig.debug | 11 +++- > lib/Makefile | 2 +- > lib/test_uuid.c | 137 +++++++++++++++++++--------------------------- > 3 files changed, 67 insertions(+), 83 deletions(-) > > -- > 2.31.1 >

It does include a summary line: [04:41:01] Testing complete. 4 tests run. 0 failed. 0 crashed. Note that this does only count the number of "tests" run --- the individual UUIDs are parameters to the same test, so aren't counted independently by the wrapper at the moment.

In my patch, I've organized in a different way, with 4 test cases: - A test case for guid_parse and guid_equal for correct inputs - A test case for uuid_parse and uuid_equal for correct inputs - A test case for guid_parse for incorrect inputs - A test case for uuid_parse for incorrect inputs So now we have 4 test cases, instead of the 6 test cases in the original code, because I've united _parse and _equal in a single test case. Given that each test has 3 parameters, this is why we see 12 test parameters and that's why there's no "18 tests" around anymore.

Hi, This patch converts existing UUID runtime test to use KUnit framework. Below, there's a comparison between the old output format and the new one. Keep in mind that even if KUnit seems very verbose, this is the corner case where _every_ test has failed. * This is how the current output looks like in success: test_uuid: all 18 tests passed * And when it fails: test_uuid: conversion test #1 failed on LE data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: cmp test #2 failed on LE data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: cmp test #2 actual data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: conversion test #3 failed on BE data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: cmp test #4 failed on BE data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: cmp test #4 actual data: 'c33f4995-3701-450e-9fbf-206a2e98e576' test_uuid: conversion test #5 failed on LE data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: cmp test #6 failed on LE data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: cmp test #6 actual data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: conversion test #7 failed on BE data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: cmp test #8 failed on BE data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: cmp test #8 actual data: '64b4371c-77c1-48f9-8221-29f054fc023b' test_uuid: conversion test #9 failed on LE data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: cmp test #10 failed on LE data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: cmp test #10 actual data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: conversion test #11 failed on BE data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: cmp test #12 failed on BE data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: cmp test #12 actual data: '0cb4ddff-a545-4401-9d06-688af53e7f84' test_uuid: negative test #13 passed on wrong LE data: 'c33f4995-3701-450e-9fbf206a2e98e576 ' test_uuid: negative test #14 passed on wrong BE data: 'c33f4995-3701-450e-9fbf206a2e98e576 ' test_uuid: negative test #15 passed on wrong LE data: '64b4371c-77c1-48f9-8221-29f054XX023b' test_uuid: negative test #16 passed on wrong BE data: '64b4371c-77c1-48f9-8221-29f054XX023b' test_uuid: negative test #17 passed on wrong LE data: '0cb4ddff-a545-4401-9d06-688af53e' test_uuid: negative test #18 passed on wrong BE data: '0cb4ddff-a545-4401-9d06-688af53e' test_uuid: failed 18 out of 18 tests * Now, here's how it looks like with KUnit: ======== [PASSED] uuid ======== [PASSED] uuid_correct_be [PASSED] uuid_correct_le [PASSED] uuid_wrong_be [PASSED] uuid_wrong_le * And if every test fail with KUnit: ======== [FAILED] uuid ======== [FAILED] uuid_correct_be # uuid_correct_be: ASSERTION FAILED at lib/test_uuid.c:57 Expected uuid_parse(data->uuid, &be) == 1, but uuid_parse(data->uuid, &be) == 0 failed to parse 'c33f4995-3701-450e-9fbf-206a2e98e576' # uuid_correct_be: not ok 1 -
