From: Rae Moar <rm...@google.com>
Update to kunit_parser to improve compatibility with KTAP
specification including arbitrarily nested tests. Patch accomplishes
three major changes:
- Use a general Test object to represent all tests rather than TestCase
and TestSuite objects. This allows for easier implementation of arbitrary
levels of nested tests and promotes the idea that both test suites and test
cases are tests.
- Print errors incrementally rather than all at once after the
parsing finishes to maximize information given to the user in the
case of the parser given invalid input and to increase the helpfulness
of the timestamps given during printing. Note that kunit.py parse does
not print incrementally yet. However, this fix brings us closer to
this feature.
- Increase compatibility for different formats of input. Arbitrary levels
of nested tests supported. Also, test cases and test suites are now
supported to be present on the same level of testing.
This patch now implements the KTAP specification as described here:
https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn...@mail.gmail.com/.
This patch adjusts the kunit_tool_test.py file to check for
the correct outputs from the new parser and adds a new test to check
the parsing for a KTAP result log with correct format for multiple nested
subtests (test_is_test_passed-all_passed_nested.log).
This patch also alters the kunit_json.py file to allow for arbitrarily
nested tests.

NOTE: this patch is now applied on top of
https://lore.kernel.org/linux-kselftest/20210930222048.1...@google.com/
to resolve a conflict.
Change log from v3:
https://lore.kernel.org/linux-kselftest/20210901190623...@google.com/
- Resolve conflict with hermetic testing patches
- Fix pytype error (str -> Optional[str] in kunit_json.py)
Change log from v2:
https://lore.kernel.org/linux-kselftest/20210826195505....@google.com/
- Fixes bug of type disagreement in kunit_json.py for build_dir
- Removes raw_output()
- Changes docstrings in kunit_parser.py (class docstring, LineStream
docstrings, add_error(), total(), get_status(), all parsing methods)
- Fixes bug of not printing diagnostic log in the case of end of lines
- Sets default status of all tests to TEST_CRASHED
- Adds and prints empty tests with crashed status in case of missing
tests
- Prints 'subtest' in instance of 1 subtest instead of 'subtests'
- Includes checking for 'BUG:' message in search of crash messages in
log (note that parse_crash_in_log method could be removed but would
require deleting tests in kunit_tool_test.py that include the crash
message that is no longer used. If removed, parser would still print
log in cases of test crashed or failure, which would now include
missing subtests)
- Fixes bug of including directives (other than SKIP) in test name
when matching name in result line for subtests
Change log from v1:
https://lore.kernel.org/linux-kselftest/20210820200032....@google.com/
- Rebase onto kselftest/kunit branch
- Add tests to kunit_tool_test.py to check parser is correctly stripping
hyphen, producing correct json objects with nested tests, correctly
passing kselftest TAP output, and correctly deals with missing test plan.
- Fix bug to correctly match test name in instance of a missing test plan.
- Fix bug in kunit_tool_test.py pointed out by Daniel where it was not
correctly checking for a proper match to the '0 tests run!' error
message. Reverts changes back to original.
- A few minor changes to commit message using Daniel's comments.
- Change docstrings using Daniel's comments to reduce:
- Shortens some docstrings to be one-line or just description if it is
self explanatory.
- Remove explicit respecification of types of parameters and returns
because this is already specified in the function annoations. However,
some descriptions of the parameters and returns remain and some contain
the type for context. Additionally, the types of public attributes of
classes remain.
- Remove any documentation of 'Return: None'
- Remove docstrings of helper methods within other methods

2.33.0.800.g4c38ced690-goog
Update to kunit_parser to improve compatibility with KTAP
specification including arbitrarily nested tests. Patch accomplishes
three major changes:
- Use a general Test object to represent all tests rather than TestCase
and TestSuite objects. This allows for easier implementation of arbitrary
levels of nested tests and promotes the idea that both test suites and test
cases are tests.
- Print errors incrementally rather than all at once after the
parsing finishes to maximize information given to the user in the
case of the parser given invalid input and to increase the helpfulness
of the timestamps given during printing. Note that kunit.py parse does
not print incrementally yet. However, this fix brings us closer to
this feature.
- Increase compatibility for different formats of input. Arbitrary levels
of nested tests supported. Also, test cases and test suites are now
supported to be present on the same level of testing.
This patch now implements the KTAP specification as described here:
https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn...@mail.gmail.com/.
This patch adjusts the kunit_tool_test.py file to check for
the correct outputs from the new parser and adds a new test to check
the parsing for a KTAP result log with correct format for multiple nested
subtests (test_is_test_passed-all_passed_nested.log).
This patch also alters the kunit_json.py file to allow for arbitrarily
nested tests.

NOTE: this patch is now applied on top of
https://lore.kernel.org/linux-kselftest/20210930222048.1...@google.com/
to resolve a conflict.
Change log from v3:
https://lore.kernel.org/linux-kselftest/20210901190623...@google.com/
- Resolve conflict with hermetic testing patches
- Fix pytype error (str -> Optional[str] in kunit_json.py)
Change log from v2:
https://lore.kernel.org/linux-kselftest/20210826195505....@google.com/
- Fixes bug of type disagreement in kunit_json.py for build_dir
- Removes raw_output()
- Changes docstrings in kunit_parser.py (class docstring, LineStream
docstrings, add_error(), total(), get_status(), all parsing methods)
- Fixes bug of not printing diagnostic log in the case of end of lines
- Sets default status of all tests to TEST_CRASHED
- Adds and prints empty tests with crashed status in case of missing
tests
- Prints 'subtest' in instance of 1 subtest instead of 'subtests'
- Includes checking for 'BUG:' message in search of crash messages in
log (note that parse_crash_in_log method could be removed but would
require deleting tests in kunit_tool_test.py that include the crash
message that is no longer used. If removed, parser would still print
log in cases of test crashed or failure, which would now include
missing subtests)
- Fixes bug of including directives (other than SKIP) in test name
when matching name in result line for subtests
Change log from v1:
https://lore.kernel.org/linux-kselftest/20210820200032....@google.com/
- Rebase onto kselftest/kunit branch
- Add tests to kunit_tool_test.py to check parser is correctly stripping
hyphen, producing correct json objects with nested tests, correctly
passing kselftest TAP output, and correctly deals with missing test plan.
- Fix bug to correctly match test name in instance of a missing test plan.
- Fix bug in kunit_tool_test.py pointed out by Daniel where it was not
correctly checking for a proper match to the '0 tests run!' error
message. Reverts changes back to original.
- A few minor changes to commit message using Daniel's comments.
- Change docstrings using Daniel's comments to reduce:
- Shortens some docstrings to be one-line or just description if it is
self explanatory.
- Remove explicit respecification of types of parameters and returns
because this is already specified in the function annoations. However,
some descriptions of the parameters and returns remain and some contain
the type for context. Additionally, the types of public attributes of
classes remain.
- Remove any documentation of 'Return: None'
- Remove docstrings of helper methods within other methods

I seem to have accidentally applied v2 so this patch is missing the
changes Rae added in v3.
--raw_output is also broken right now, since I didn't update it enough
to resolve the conflicts with the hermetic testing patches.
I'll send a v4 when I get that sorted out.

NOTE: this patch is now applied on top of
https://lore.kernel.org/linux-kselftest/20210930222048.1...@google.com/
to resolve a conflict.
Change log from v3,4:
NOTE: this patch is now applied on top of
https://lore.kernel.org/linux-kselftest/20210930222048.1...@google.com/
to resolve a conflict.
https://lore.kernel.org/linux-kselftest/20210901190623...@google.com/
- Move test_kselftest_nested from LinuxSourceTreeTest => KUnitParserTest.
- Resolve conflict with hermetic testing patches.
- max_status is no longer defined, so we need to use the TestCounts
type now. And to keep --raw_output working, we need to set this to
SUCCESS to avoid the default assumption that the kernel crashed.
Ignore v4, was accidentally based on v2.
Change log from v2:

(Nit: Also maybe remove the '.' from the end of the link. It does
actually work, but it's cleaner without.)

I tested in in a few different situations, and it seemed to work well
in all of them.
One exception was the KFENCE tests (and presumably the Thunderbolt
ones, too), which run at an odd time and leave the test numbers
incorrect. That's a bug in the tests (and possibly the KUnit
executor), I've posted this patch to fix it:
https://lore.kernel.org/linux-kselftest/20211006044111.2...@google.com/
My only real desire is that we get rid of the error when a KTAP test
plan line is missing. With this patch, everything works pretty well in
that case anyway, so there's no need for an error. This will be needed
as a prerequisite for making test parameters subtests, as it's not
necessarily known in advance how many parameters the generate will
produce.
Otherwise, there are a couple of minor nitpicks, but it looks good to me:

input reports "No tests run" rather than "missing plan line~".
hermetic testing test list. It could just as easily be added in a
follow-up though, so don't hold this patch up over it.
know how many parameters they'll generate in advance, so when we
convert those to use subtests, we'll get an error for every test with
subtests.
Note that if we get rid of that, there are a few bits of the
documentation / tests which may need updating, too.
As an example of what this error looks like for parameterised tests:
[22:07:30] =============== ext4_inode_test (1 subtest) ================
[22:07:30] [ERROR] Test inode_test_xtimestamp_decoding: missing plan line!
[22:07:30] ============== inode_test_xtimestamp_decoding ==============
[22:07:30] [PASSED] 1901-12-13 Lower bound of 32bit < 0 timestamp, no extra bits
[22:07:30] [PASSED] 1969-12-31 Upper bound of 32bit < 0 timestamp, no extra bits
...
Combined with extra errors reported in the final summary.
I'll post the patch for making parameters report results as KTAP
subtests later today.

again after reapplying.
There's a few follow-on patches I would want to send as well.
E.g. I have a change to LineStream that makes it fully lazy, which
would be now sufficient to make the parser print out tests
incrementally.
I looked at it, and I think the docstring above makes it clear enough
that we can leave the comment off.
(it's much closer to this line when the diff is applied)
I still haven't figured out what kind of string we'd want to put there.
"KTAP test list" or something like that?
I didn't want to make that change in this patch because
a) the fact I don't want to change this too substantially
b) I feel like there are some knock-on effects of making it optional.

From: Rae Moar <rm...@google.com>
Update to kunit_parser to improve compatibility with KTAP
specification including arbitrarily nested tests. Patch accomplishes
three major changes:
- Use a general Test object to represent all tests rather than TestCase
and TestSuite objects. This allows for easier implementation of arbitrary
levels of nested tests and promotes the idea that both test suites and test
cases are tests.
- Print errors incrementally rather than all at once after the
parsing finishes to maximize information given to the user in the
case of the parser given invalid input and to increase the helpfulness
of the timestamps given during printing. Note that kunit.py parse does
not print incrementally yet. However, this fix brings us closer to
this feature.
- Increase compatibility for different formats of input. Arbitrary levels
of nested tests supported. Also, test cases and test suites are now
supported to be present on the same level of testing.
This patch now implements the draft KTAP specification here:

We'll update the parser as the spec evolves.
This patch adjusts the kunit_tool_test.py file to check for
the correct outputs from the new parser and adds a new test to check
the parsing for a KTAP result log with correct format for multiple nested
subtests (test_is_test_passed-all_passed_nested.log).
This patch also alters the kunit_json.py file to allow for arbitrarily
nested tests.

Take this output, for example:
[19:32:07] # Subtest: kasan
[19:32:07] 1..48
[19:32:07] # kasan: pass:42 fail:0 skip:6 total:48
[19:32:07] # Totals: pass:42 fail:0 skip:6 total:48
[19:32:07] ok 1 - kasan
[19:32:07] ===================== [CRASHED] kasan ======================
[19:32:07] ============================================================
[19:32:07] Testing complete. Passed: 4, Failed: 0, Crashed: 38,
Skipped: 6, Errors: 0
The in-kernel totals are correctly: 42 passed, 7 skipped, 0 failed. In
kunit_tool, only 4 tests are recorded as passed, and 38 are marked as
crashed.
KASAN errors in the log (which are expected), and these messages do
contain "BUG:".
Even though the KASAN integration code then marks the test as success,
and it shows up as "ok" in the KTAP output, kunit_tool now marks it as
crashed.
There are two obvious solutions to this:
- Update KASAN to not include "BUG" in the message for KASAN failures
which are expected.
- Alter this patch to not mark tests as crashed just because they have
"BUG" in their logs.
(There are also more complicated solutions, like having a "failure
expected" message added to the log, and only ignoring "BUG:" if that
exists in kunit_tool, but that seems needlessly complicated.)
I feel that, in the short term, we should revert this change, and not
treat "BUG:" specially. We can add it back in as a separate patch if
we want to fix this issue differently.
Doing so makes the KASAN results come out correctly.

I also found another bug relating to test status counting.
If there's NO_TESTS, add_status() will increment the counts.passed field.
This means if you get
$ ./tools/testing/kunit/kunit.py exec 'nomatch'
[10:13:34] Starting KUnit Kernel (1/1)...
[10:13:34] ============================================================

I'm just not sure what the intent behind the SUCCESS or NO_TESTS checks was.

- don't have 1 "passed" test when no tests run
- don't treat BUG as a kernel crash (KASAN tests print this out normally)
- Fixes bug of including directives (other than SKIP) in test name
when matching name in result line for subtests
Change log from v1:
https://lore.kernel.org/linux-kselftest/20210820200032....@google.com/
- Rebase onto kselftest/kunit branch
- Add tests to kunit_tool_test.py to check parser is correctly stripping
hyphen, producing correct json objects with nested tests, correctly
passing kselftest TAP output, and correctly deals with missing test plan.
- Fix bug to correctly match test name in instance of a missing test plan.
- Fix bug in kunit_tool_test.py pointed out by Daniel where it was not
correctly checking for a proper match to the '0 tests run!' error
message. Reverts changes back to original.
- A few minor changes to commit message using Daniel's comments.
- Change docstrings using Daniel's comments to reduce:
- Shortens some docstrings to be one-line or just description if it is
self explanatory.
- Remove explicit respecification of types of parameters and returns
because this is already specified in the function annoations. However,
some descriptions of the parameters and returns remain and some contain
the type for context. Additionally, the types of public attributes of
classes remain.
- Remove any documentation of 'Return: None'
- Remove docstrings of helper methods within other methods

Slightly tweaked the diff below to make "NO_TESTS" print out in yellow, not red.
