Subject: [PATCH] kunit: tool: improve compatibility of kunit_parser with KTAP specification
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 test 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.
- 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+GJov6tdjvY9x12JsJT14qn6c7NViJxqaJk+r-K1YJzPggFDQ@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.
