How to properly unit test jQuery's .ajax() promises using Jasmine and/or Sinon?

Question

I\'ve got a fairly straightforward function which returns a jQuery .ajax() promise as such:

CLAW.controls.validateLocation = function(val, $inputEl) {
    re         


        

Answer 1

something along these lines / with sinon and jQuery deferreds

ajaxStub = sinon.stub($, "ajax");

function okResponse() {
  var d = $.Deferred();
  d.resolve( { username: "testuser", userid: "userid", success: true } );
  return d.promise();
};

function errorResponse() {
 var d = $.Deferred();
 d.reject({},{},"could not complete");
 return d.promise();
};

ajaxStub.returns(okResponse());
ajaxStub.returns(errorResponse());
