sinon.js stub - can you call more than one callback on a single stubbed function?

Question

If I have a stub for a function that takes 2 callbacks, how can I wire up sinon.js to call both callbacks when the stubbed function is invoked?

For exam

Answer 1

Why don't you skip sinon altogether?

var obj = { stubMe: function(cb1, cb2) {} };
var originalMethod = obj.stubMe;

obj.stubMe = function(cv1, cb2) { 
  //Whatever logic you wish
  cb1(); 
  cb2(); 
}; 

//Do your test

obj.stubMe = originalMethod; //Restore

This way you can even continue to use sinon's APIs, if you wish:

var stub = sinon.stub();
obj.stubMe = function(cb1, cb2) { 
  stub.apply(stub, arguments);
  //Rest of whatever logic you wanted here
};

obj.stubMe();
expect(stub.calledOnce()).to.be(true); //That would pass

What'd you think?
