Change the KUnit parser to be able to parse test output that complies with
the KTAP version 1 specification format found here:
https://kernel.org/doc/html/latest/dev-tools/ktap.html. Ensure the parser
is able to parse tests with the original KUnit test output format as
well.
KUnit parser now accepts any of the following test output formats:
Original KUnit test output format:
TAP version 14
1..1
# Subtest: kunit-test-suite
1..3
ok 1 - kunit_test_1
ok 2 - kunit_test_2
ok 3 - kunit_test_3
# kunit-test-suite: pass:3 fail:0 skip:0 total:3
# Totals: pass:3 fail:0 skip:0 total:3
ok 1 - kunit-test-suite
KTAP version 1 test output format:
KTAP version 1
1..1
KTAP version 1
1..3
ok 1 kunit_test_1
ok 2 kunit_test_2
ok 3 kunit_test_3
ok 1 kunit-test-suite
New KUnit test output format (changes made in the next patch of
this series):
KTAP version 1
1..1
KTAP version 1
# Subtest: kunit-test-suite
1..3
ok 1 kunit_test_1
ok 2 kunit_test_2
ok 3 kunit_test_3

# Totals: pass:3 fail:0 skip:0 total:3

Changes since v1:
https://lore.kernel.org/all/[email protected]/
- Switch order of patches to make changes to the parser before making
changes to the test output
- Change placeholder label for test header from “Test suite” to empty
string
- Change parser to approve the new KTAP version line in the subtest header
to be before the subtest header line rather than after.
- Note: Considered changing parser to allow for the top-level of testing
to have a '# Subtest' line as discussed in v1 but this breaks the
missing test plan test. So I think it would be best to add this ability
at a later time or after top-level test name and result lines are
discussed for KTAP v2.

Still looks good to me overall.
As noted offline, this sadly has a conflict with another recent patch,
so it won't apply to the kunit branch right now.
That's my fault:
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/commit/?h=kunit&id=2a883a9f5c1f1c7bb9d9116da68e2ef2faeae5b8
I found a few optional nits down below that we could also address in
the rebased v3.

Thanks, as noted on the child patch, I think this will make our lives
easier in the future, even if it technically violates the v1 spec
(which requires the test plan right after the KTAP header IIUC).
Given the wording
Diagnostic lines can be anywhere in the test output.
I assume most implementations would likely ignore unexpected lines
beginning with "# " already.

Thanks, I like this output a lot better than having "Test suite" as a
placeholder name.

LGTM (this is where we changed to parse the KTAP header before " # Subtest").
Optional: do we want to extend kunit_tool_test.py to validate this logic too?
E.g. given input like
KTAP version 1
1..1
KTAP version 1
# Subtest: suite
1..1
ok 1 - test
ok 1 - subtest
we could assert that the parsed output contains "suite (1 subtest)"
i.e.
self.print_mock.assert_any_call(StrContains('suite (1 subtest)'))
