If we skip one parametrized test case then test status remains SKIP for all subsequent test params leading to wrong reports:
$ ./tools/testing/kunit/kunit.py run \ --kunitconfig ./lib/kunit/.kunitconfig *.example_params* --raw_output \
[ ] Starting KUnit Kernel (1/1)... KTAP version 1 1..1 # example: initializing suite KTAP version 1 # Subtest: example # module: kunit_example_test 1..1 KTAP version 1 # Subtest: example_params_test # example_params_test: initializing # example_params_test: cleaning up ok 1 example value 3 # SKIP unsupported param value 3 # example_params_test: initializing # example_params_test: cleaning up ok 2 example value 2 # SKIP unsupported param value 3 # example_params_test: initializing # example_params_test: cleaning up ok 3 example value 1 # SKIP unsupported param value 3 # example_params_test: initializing # example_params_test: cleaning up ok 4 example value 0 # SKIP unsupported param value 0 # example_params_test: pass:0 fail:0 skip:4 total:4 ok 1 example_params_test # SKIP unsupported param value 0 # example: exiting suite ok 1 example # SKIP
Reset test status and status comment after each param iteration to avoid using stale results.
