unit test typescript webresources d365

Hi any reference for typescript webresources where we can mock Xrm.Utility.getGlobalContext(), XrmQuery. In our project we are using Xrm.d.ts instead of xRM 

I am using jest , xrm-mock library to right unit test but xrm-mock have onlky basic or limited mocks. 

It would be great if anyone can provide some samples that they have implemented in their project to unit test typescripts.

Thanks,

Tejaswini
