Mock free functions

[johanblumenberg]

Mock free functions, without the need for any class to mock

Example:

let fn: (a: number, b: string) => number = fnmock();
when(fn(10, 'hello')).thenReturn(5);

instance(fn)(10, 'hello'); // returns 5

verify(fn(10, 'hello')).called();

Typescript 3.0+ is required for matching rest args to a tuple type, in this function signature:

export function fnmock<R, T extends any[]>(): (...args: T) => R {

Is there really no way to mock an unbound function at the moment?
This is much needed functionality then.

I don't like the name fnmock though, it's not in style with other names. Could it be possible to use mock(Function) or rename to functionMock?

Can we resolve conflicts and get this in? @NagRock
