Current behavior

createSpyObject is public api for Jasmine, but only internal for Jest.

Expected behavior

It should be public api for both environments.

Minimal reproduction of the problem with instructions

Not applicable.

What is the motivation / use case for changing the behavior?

For homogeneity it's desireable to manually mock objects in the same way that spectator mocks objects automatically. In fact that's already possible with public api by using mockProvider(type, properties).useFactory(). However that's rather unintuitive to write out all the time ;).

Environment

Not relevant.
