Unable to spy function inside ajax success callback and forEach.

[tiag...@sportlobster.com]

thanks in advance, I am trying to test a function that is called on ajax success callback and then inside a forEach. (trackTaxonomyEvent())

But I am always getting

Error: Expected spy trackTaxonomyEvent to have been called

If I move the function out of the forEach it works.

code.js

saveFanzones: function(closeOnSave) {
    this.selectedTaxonomyCollection.create({
        taxonomy_ids: newTaxaonomiesId.join(',')
    }, {
        success: function() {
            _.forEach(this.selectedTaxonomyCollection.where({
                user_selected: true
            }), function(fanzoneModel) {

                var params = {
                    id: fanzoneModel.get('id')
                };

                this.trackTaxonomyEvent('fanzone:join',params);
            }.bind(this));
        }.bind(this)
    });
});

code.spec.js

it('Ajax call correct URL', function() {
    spyOn($, 'ajax').and.callFake(function(params) {
        params.success('1');
    });
    spyOn(view, 'trackTaxonomyEvent').and.callThrough();

    view.saveFanzones();
    expect(view.trackTaxonomyEvent).toHaveBeenCalled();
});

Typically, when I've seen this sort of behavior, it's because the code under test saves off a reference to the actual function being spied on which isn't something that jasmine can update. Everything in your example looks like it should work as you expect. Do you have a more complete example (anonymized however makes sense to you) that you can share to help debug the issue?

Thanks for using Jasmine!
