[czgdp1807]

This issue aims to fix the tests which are failing for split layer in ONNXImporter. The problem was discovered while working on #16424
Specifically see, #16424 (comment)
Please comment more such failing tests if you come across any.

@dkurt Can you please tell me the commands for building the failing tests locally? I want to re-produce the errors on my system for fixing. Thanks.

Hi @dkurt
I executed the tests for split layer.

Note: Google Test filter = *ONNX*Split/*
[==========] Running 4 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 4 tests from Test_ONNX_layers
[ RUN      ] Test_ONNX_layers.Split/0, where GetParam() = DLIE/CPU
[     SKIP ] Test with tag 'dnn_skip_ie_nn_builder' is skipped ('dnn_skip_ie_nn_builder' is in skip list)
[       OK ] Test_ONNX_layers.Split/0 (0 ms)
[ RUN      ] Test_ONNX_layers.Split/1, where GetParam() = OCV/OCL
3
[       OK ] Test_ONNX_layers.Split/1 (33 ms)

[ RUN      ] Test_ONNX_layers.Split/3, where GetParam() = OCV/CPU

[       OK ] Test_ONNX_layers.Split/3 (5 ms)
[----------] 4 tests from Test_ONNX_layers (52 ms total)

[----------] Global test environment tear-down
[ SKIPSTAT ] 1 tests skipped
[ SKIPSTAT ] TAG='dnn_skip_ie_nn_builder' skip 1 tests
[==========] 4 tests from 1 test case ran. (52 ms total)
[  PASSED  ] 4 tests.

Why Split/0 is skipped? Please let me know what I have to do to run NGRAPH/CPU tests as they were the ones failing in the other PR. Thank you.

@czgdp1807, so it's skipped because it's failed.

Call ./bin/opencv_test_dnn --help to see available flags. BTW, maybe this PR may fix the test: #16628

Thanks for the update. I will try the above command.
