The functionality of Angular services is not available for use in Jasmine tests

As someone who is relatively new to Jasmine Testing and the Angular framework, I find myself in a unique situation. I am currently struggling with referencing my service functions in my Jasmine tests.

Here is a snippet of my Angular Service Initialization:

var service = {
checkIfCurrentIsObject: checkIfCurrentIsObject,
removeFromCurrentObject: removeFromCurrentObject;
}

function checkIfCurrentIsObject() {
          return getCurrent().isObject();
       }

function removeFromCurrentIsObject() {
         checkIfCurrentIsObject();
          return specialFunction();
       }

Now, in my Karma Test:

describe('when current object is property', function() {

             it('verify the requote function is called', function() {
             spyOn(Service, 'checkIfCurrentIsObject').and.returnValue(true);
             spyOn(Service, 'removeFromCurrentIsObject').and.callThrough();
             spyOn(Service, 'specialFunction');
             expect(Service, 'specialFunction').toHaveBeenCalled();

                    });

The issue I am currently facing is that my spyOn method does not detect my checkIfCurrentIsObject function unless I specifically reference it as this.checkIfCurrentIsObject in my removeFromCurrentIsObject function. Can anyone shed light on why this might be happening?

Answer №1

Affirmative, that is the correct approach

 function executeSpyOnCurrentObject() {
     this.inspectCurrentObject();
     return this.triggerSpyAction();
 }

to secretly monitor their activities.

Specifically, the method being monitored is Service.inspectCurrentObject. In the realm of JavaScript, it is impossible to track the invocation of a local function like inspectCurrentObject().
