Jasmine calling function with ajax returned value - ajax

Question

I want to test the "addGroup" function using Jasmine. I get the following error:
Error: Expected spy modifyMyHtml to have been called.at null.
I don't know what is the best way to test the addGroup function. Please HELP.....
var myRecord = {
addGroup: function(groupNumber) {
$.when(myRecord.getHtml())
.done(function(returnedHtml){
myRecord.modifyMyHtml(returnedHtml);
});
},
getHtml: function() {
return $.ajax({url: "myHtmlFile.html", dataType: "html" });
},
// adds options and events to my returned HTML
modifyMyHtml: function(returnedHtml) {
$('#outerDiv').html(returnedHtml);
var myOptions = myRecord.getOptions();
$('#optionsField').append(myOptions);
myRecord.bindEventsToDiv();
},
}
====JASMINE TEST
describe("Configure Record page", function() {
var fixture;
jasmine.getFixtures().fixturesPath = "/test/" ;
jasmine.getFixtures().load("myHtmlFile.html");
fixture = $("#jasmine-fixtures").html();
describe("addGroup", function(){
beforeEach(function() {
var groupNumber = 0;
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().promise();
});
spyOn(myRecord, "modifyMyHtml");
myRecord.addGroup(groupNumber);
});
it("Should call getHtml", function() {
expect(myRecord.getHtml).toHaveBeenCalled();
});
it("Should call modifyMyHtml", function() {
expect(myRecord.modifyMyHtml).toHaveBeenCalled(); ==>FAILS
});
});
});

Answer 1

You have to resolve the promise before you return em in your andCallFake.
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().resolve ().promise();
});
Btw. you should not test that the function on the object you wanna test are called, but that the html in the DOM are set with the right html
it("Should call modifyMyHtml", function() {
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().resolveWith(null, 'returnedHtml').promise();
});
expect($('#outerDiv').html).toEqual('returnedHtml')
});
