It's possible for a test to have a subtest header, but zero valid
subtests. We used to error on this if the test plan had no subtests
listed, but it's possible to have subtests without a test plan (indeed,
this is how parameterised tests work).
Tests with 0 subtests now have the result NO_TESTS, and will report an
error (which does not halt test execution, but is printed in a scary red
colour and is noted in the results summary).

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:
https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn6c7NViJxqaJk+r-K1YJzPggFDQ@mail.gmail.com/
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.

This patch addresses misleading error messages reported by kunit_tool in
two cases. First, in the case of TAP output having an incorrect header
format or missing a header, the parser used to output an error message of
'no tests run!'. Now the parser outputs an error message of 'could not
parse test results!'.
As an example:
Before:
$ ./tools/testing/kunit/kunit.py parse /dev/null
[ERROR] no tests run!
...
After:
$ ./tools/testing/kunit/kunit.py parse /dev/null
[ERROR] could not parse test results!
...
Second, in the case of TAP output with the correct header but no
tests, the parser used to output an error message of 'could not parse
test results!'. Now the parser outputs an error message of 'no tests
run!'.
As an example:
Before:
$ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse
[ERROR] could not parse test results!
After:
$ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse
[ERROR] no tests run!
Additionally, this patch also corrects the tests in kunit_tool_test.py
and adds a test to check the error in the case of TAP output with the
correct header but no tests.

Add support for the SKIP directive to kunit_tool's TAP parser.
Skipped tests now show up as such in the printed summary. The number of
skipped tests is counted, and if all tests in a suite are skipped, the
suite is also marked as skipped. Otherwise, skipped tests do affect the
suite result.
Example output:
[00:22:34] ======== [SKIPPED] example_skip ========
[00:22:34] [SKIPPED] example_skip_test # SKIP this test should be skipped
[00:22:34] [SKIPPED] example_mark_skipped_test # SKIP this test should be skipped
[00:22:34] ============================================================
[00:22:34] Testing complete. 2 tests run. 0 failed. 0 crashed. 2 skipped.

Some tests logs for kunit_tool tests are missing their test plans
causing their tests to fail; fix this by adding the test plans.

TAP 14 allows an optional test plan to be emitted before the start of
the start of testing[1]; this is valuable because it makes it possible
for a test harness to detect whether the number of tests run matches the
number of tests expected to be run, ensuring that no tests silently
failed.

Currently, if the kernel is configured incorrectly or if it crashes before any
kunit tests are run, kunit finishes without error, reporting
that 0 test cases were run.
To fix this, an error is shown when the tap header is not found, which
indicates that kunit was not able to run at all.

Previously, kunit_parser did not properly handle kunit TAP output that
- had any prefixes (generated from different configs e.g.
CONFIG_PRINTK_TIME)
- had unrelated kernel output mixed in the middle of
it, which has shown up when testing with allyesconfig
To remove prefixes, the parser looks for the first line that includes
TAP output, "TAP version 14". It then determines the length of the
string before this sequence, and strips that number of characters off
the beginning of the following lines until the last KUnit output line is
reached.
These fixes have been tested with additional tests in the
KUnitParseTest and their associated logs have also been added.

The ultimate goal is to create minimal isolated test binaries; in the
meantime we are using UML to provide the infrastructure to run tests, so
define an abstract way to configure and run tests that allow us to
change the context in which tests are built without affecting the user.
This also makes pretty and dynamic error reporting, and a lot of other
nice features easier.
kunit_config.py:
- parse .config and Kconfig files.
kunit_kernel.py: provides helper functions to:
- configure the kernel using kunitconfig.
- build the kernel with the appropriate configuration.
- provide function to invoke the kernel and stream the output back.
kunit_parser.py: parses raw logs returned out by kunit_kernel and
displays them in a user friendly way.
test_data/*: samples of test data for testing kunit.py, kunit_config.py,
etc.
