/**
* For any type T, generate a new type that is identical but also has the
* jest.fn signature on all member functions.
*
* When writing tests against a type, you sometimes end up in a situation where
* you need to write expect(x.y as jest.Mock).toHaveBeenCalled... because the
* x.y member was considered to be the actual function type. You could also
* change your test to instead create a "raw" object { y: jest.fn() } but then
* you lose type safety when doing x.y.mockReturnValue(...). So you start
* trying to do { y: jest.fn() as X['y'] } as X or similar trickery.
*
* This type lets you say const x: MockedMemberFunctions<X> = { y: jest.fn() }
* and keep all the type safety at every step.
