CUnit provides a helper macro CU_ADD_TEST() that simplifies usage of CU_add_test() function. Test name no longer needs to be provided, as it will be inherited from function name. This is a follow up to https://review.spdk.io/gerrit/c/spdk/spdk/+/931 Change-Id: I8078f02e08b14f12328ae022d7090ba13fbd64e4 Signed-off-by: Vitaliy Mysak <vitaliy.mysak@intel.com> Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/1239 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com> Reviewed-by: Tomasz Zawadzki <tomasz.zawadzki@intel.com>
