I have a class in jquery that calls a service and returns a promise, which is then executed in my main area via a .done and Im trying to wrap that call in a another class I have that will make sure multiple calls are not made for the same ID. However I am finding this very very difficult to test as I can not accurcately get the promise working in phantomJS/Sinon. Heres what the area Im trying to test is
LOCKER.execute(diagRunId, function (unlock) {
SERVICE_ACCESSOR.makeCall params)
.done(function (data) {
console.log("Success!");
unlock();
})
.fail(function (jqXHR, textStatus, errorThrown) {
console.log("Failed!");
unlock();
});
});
and In my test file I have my setup like so
var setup = function() {
P.mock('service-accessor', function () {
return {
makeCall: sinon.stub().returns({})
};
});
P.mock('locker', function () {
var methods = {
execute: function (lockId, wrapped) {
console.log('locked - ' + lockId)
wrapped()
},
unlock: sinon.stub()
};
return {
execute: methods.execute,
unlock: methods.unlock
};
});
P.start();
}
with finally the test just calling the method
aui.suite('Locker Test', function () {
aui.test('should lock and then unlock', testFile, {
setup: setup,
browser: function () {
P.when('utils', 'service-accessor','locker').execute(
'test', function (SERVICE_ACCESSOR, LOCKER) {
UTILS.makeCall("Identifier")
expect(LOCKER.unlock).to.have.been.called.once;
done();
}
);
},
validate: function () {},
});
});
The locker works and begins execution of the service call, but then the service call fails with
Error: PhantomJS: `TypeError: 'undefined' is not a function (evaluating 'SERVICE_ACCESSOR.callService( params).done')` near
L2492> }).fail(function (jqXHR, textStatus, errorThrown) {
From my understanding my mock should return a just a empty object when its being called, but then I dont understand a) Why its going to fail and b) Whats undefined? My assumption is that its because Im not returning three objects, but Im trying to get it to succeed first! How can I correctly stub/mock this?
In the end I didn't make a promise or use a stub. I used the following function that would call the done and fail in my call instead.
function() {
return { done: function(callback) {
if(window.makeParamountCallSuccess) {
callback({"data": "data"});
return {
fail: function(){}
}
} else {
return {
fail: function(failCallback){ failCallback("jqXHR", "textStatus", "errorThrown")}
}
}
}
}
}```
