Thanks for your work! LGTM but, I found some skips depending on XPU and CUDA. I think unit test should be available on all environments. Could you remove skip and mock properly?

Some of the tests works only when XPU device because those part of the code works only with specific device. We can't run it for all devices because IPEX that required to be imported is not available for cuda.
