Note that this output is from the kunit_tool script, which parses the test output. 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.
That being said, the raw output looks like this (all tests passed): TAP version 14 1..1 # Subtest: uuid 1..4 # uuid_correct_be: ok 1 - c33f4995-3701-450e-9fbf-206a2e98e576 # uuid_correct_be: ok 2 - 64b4371c-77c1-48f9-8221-29f054fc023b # uuid_correct_be: ok 3 - 0cb4ddff-a545-4401-9d06-688af53e7f84 ok 1 - uuid_correct_be # uuid_correct_le: ok 1 - c33f4995-3701-450e-9fbf-206a2e98e576 # uuid_correct_le: ok 2 - 64b4371c-77c1-48f9-8221-29f054fc023b # uuid_correct_le: ok 3 - 0cb4ddff-a545-4401-9d06-688af53e7f84 ok 2 - uuid_correct_le # uuid_wrong_be: ok 1 - c33f4995-3701-450e-9fbf206a2e98e576 # uuid_wrong_be: ok 2 - 64b4371c-77c1-48f9-8221-29f054XX023b # uuid_wrong_be: ok 3 - 0cb4ddff-a545-4401-9d06-688af53e ok 3 - uuid_wrong_be # uuid_wrong_le: ok 1 - c33f4995-3701-450e-9fbf206a2e98e576 # uuid_wrong_le: ok 2 - 64b4371c-77c1-48f9-8221-29f054XX023b # uuid_wrong_le: ok 3 - 0cb4ddff-a545-4401-9d06-688af53e ok 4 - uuid_wrong_le ok 1 - uuid
A test which failed could look like this: # uuid_correct_le: ASSERTION FAILED at lib/test_uuid.c:46 Expected guid_parse(data->uuid, &le) == 0, but guid_parse(data->uuid, &le) == -22
failed to parse 'c33f499x5-3701-450e-9fbf-206a2e98e576' # uuid_correct_le: not ok 1 - c33f499x5-3701-450e-9fbf-206a2e98e576 # uuid_correct_le: ok 2 - 64b4371c-77c1-48f9-8221-29f054fc023b # uuid_correct_le: ok 3 - 0cb4ddff-a545-4401-9d06-688af53e7f84 not ok 2 - uuid_correct_le
Thanks!
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.
Did the test statistics patch we sent out before meet your expectations? https://patchwork.kernel.org/project/linux-kselftest/patch/20201211072319.53...
Let me look at it at some point.
If so, we can tidy it up and try to push it through straight away, we were just waiting for a review from someone who wanted the feature.
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
There are some small restrictions on the exact format KUnit can use for this if we want to continue to match the (K)TAP specification which is being adopted by kselftest. The patch linked above should give something formatted like:
# test_uuid: (0 / 4) tests failed (0 / 12 test parameters)
Would that work for you?
Can you decode it for me, please?
(Assuming that the above question arisen, perhaps some rephrasing is needed. The idea that user should have clear understanding on how many test cases were run and how many of them successfully finished or failed. According to this thread I have to see the cumulative number of 18 (either as one number or sum over test cases or how you call them, I see 4 here).
In the original code, each `if(uuid/guid_parse/equal)` was considered as a test, so there were 4 tests for the 3 correct inputs and 2 tests for the 3 wrong inputs: 4 * 3 + 2 * 3 = 18 tests.
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.
