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
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?
This is not a classic scenario, since not many methods would call two methods sequentially, and I guess thats why it isn't supported. But, be calm, the solution is easy:
var subject = {
method: function(one, two) {}
};
var stub = sinon.stub(subject, 'method', function(one, two) {
one();
two();
});
subject.method(
function() { console.log('callback 1'); },
function() { console.log('callback 2'); });
Side note: This also gives the option for choosing if one or two should be called first.
