var getWriterName = function(b,c) {

var sandbox = sinon.sandbox.create();

But this gives me an error of

TypeError: Attempted to wrap undefined property undefined as function

What is wrong with my stubbing if I am in the write path?

If my functions are in a file called main.js then firstly I'd rewire the file as:

var main = rewire('main');

Then to stub any other function being called in one function, in my case, when I had to stub getWriterName I'd do:

main.__set__('getWriterName', function(b, c) {
    return 'Something Else'

and Finally after finishing using it, do
