Jest support for NativeScript + Angular.

[james-spears]

Is your feature request related to a problem? Please describe.

I'm always frustrated when I try to unit test my NativeScript + Angular application using Jest.

Describe the solution you'd like

I would appreciate support for using Jest with NativeScript + Angular.

Describe alternatives you've considered

Please see this stackoverflow question, where I outline my struggles. What is holding it back at the moment is transpilation of @nativescript/core and @nativescript/angular prior to running the tests. There are some import statements which Jest does not like, and when I follow the instructions from Jest and instruct ts-jest or babel-jest to transpile, I get another error about not being able to find ./application, or ~package.json.

Additional context

With guidance I would be willing to continue working the problem and search for a solution. Or some comments and/or responses to my stackoverflow question would be greatly appreciated, even if it is to comment on why it cannot easily be done. Thank you.
