Accept undefined as function

From time to time I just want to create a mock and do not care about the return value of a function, often for functions that create side effects.

To mock these functions I currently have to do something like:

const myMock = spy(() => null);

I want to be able to just call spy without arguments:

const myMock = spy();

Implementation suggestion:

-function spy(fn) {
+function spy(fn = () => undefined) {

There should be linting as part of test script.

codecov
