[PATCH v3 0/3] kunit: Fix reporting of the skipped parameterized tests

[Michal Wajdeczko <michal.wajdeczko@xxxxxxxxx>]

Due to the lack of the SKIP directive in the output, if any of the
parameterized test was skipped, the parser could not recognize that
correctly and was marking the test as PASSED.

This can easily be seen by running the new subtest from patch 1:

$ ./tools/testing/kunit/kunit.py run \
	--kunitconfig ./lib/kunit/.kunitconfig *.example_params*

  [ ] Starting KUnit Kernel (1/1)...
  [ ] ============================================================
  [ ] =================== example (1 subtest) ====================
  [ ] =================== example_params_test  ===================
  [ ] [PASSED] example value 2
  [ ] [PASSED] example value 1
  [ ] [PASSED] example value 0
  [ ] =============== [PASSED] example_params_test ===============
  [ ] ===================== [PASSED] example =====================
  [ ] ============================================================
  [ ] Testing complete. Ran 3 tests: passed: 3

$ ./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
      1..1
          KTAP version 1
          # Subtest: example_params_test
      # example_params_test: initializing
          ok 1 example value 2
      # example_params_test: initializing
          ok 2 example value 1
      # example_params_test: initializing
          ok 3 example value 0
      # example_params_test: pass:2 fail:0 skip:1 total:3
      ok 1 example_params_test
  # Totals: pass:2 fail:0 skip:1 total:3
  ok 1 example

After adding the SKIP directive, the report looks as expected:

  [ ] Starting KUnit Kernel (1/1)...
  [ ] ============================================================
  [ ] =================== example (1 subtest) ====================
  [ ] =================== example_params_test  ===================
  [ ] [PASSED] example value 2
  [ ] [PASSED] example value 1
  [ ] [SKIPPED] example value 0
  [ ] =============== [PASSED] example_params_test ===============
  [ ] ===================== [PASSED] example =====================
  [ ] ============================================================
  [ ] Testing complete. Ran 3 tests: passed: 2, skipped: 1

  [ ] Starting KUnit Kernel (1/1)...
  KTAP version 1
  1..1
      # example: initializing suite
      KTAP version 1
      # Subtest: example
      1..1
          KTAP version 1
          # Subtest: example_params_test
      # example_params_test: initializing
          ok 1 example value 2
      # example_params_test: initializing
          ok 2 example value 1
      # example_params_test: initializing
          ok 3 example value 0 # SKIP unsupported param value
      # example_params_test: pass:2 fail:0 skip:1 total:3
      ok 1 example_params_test
  # Totals: pass:2 fail:0 skip:1 total:3
  ok 1 example

v2: better align with future support for arbitrary levels of testing
v3: rebased on kunit tree [1]
