// Unlike INSTANTIATE_TEST_CASE_P we don't currently support passing a custom param

// NGRAPH_INSTANTIATE_TEST_CASE_P(BACKENDNAME, // backend_name
// , // empty/skipped prefix
// TestWithParamSubClass, // test_case_name
// ::testing::Range(0, 3) ) // test generator
// would generate:
// BACKENDNAME/TestWithParamSubClass.test_name/0
// BACKENDNAME/TestWithParamSubClass.test_name/1
// BACKENDNAME/TestWithParamSubClass.test_name/2

// NGRAPH_INSTANTIATE_TEST_CASE_P(BACKENDNAME, // backend_name
// NumericRangeTests, // prefix
// TestWithParamSubClass, // test_case_name
// ::testing::Range(0, 3) ) // test generator
