Testing the API responces format returned by angular service with Jasmine

The majority of the problems occur when the format of the interaction between me and the API changes. I want to test my angular service which talks with the API. How can I inject my angular service into test and get proper results if this service uses $http? Should I use jasmine, the tool for unit testing for this type of integration tests?

In this example I'm testing the OntologyService which uses $http and returns a promise, and the test looks like this:

describe('Service: OntologyService', function () {
    var OntologyService, $scope;
    beforeEach(function () {
        module('oneClickRegistrationApp');
        inject(function ($injector) {
            OntologyService = $injector.get('OntologyService');
            $scope = $injector.get('$rootScope').$new();
        });
    });

    it('should return the object of ontologies', inject(function () {
        var ontoServerApiUrl = 'http://ift.tt/28QntRW';
        OntologyService.getAllOntologies(ontoServerApiUrl).then(function (ontologies) {
            expect(ontologies).toBeNonEmptyObject();
            expect(ontologies["licenses"]).toHaveArrayOfObjects();
            expect(ontologies["species"]).toHaveArrayOfObjects();
            expect(ontologies["measurement_methods"].length).toBeGreaterThan(10);
        });
        $scope.$digest();
    }));
});

I'm getting the following error message:

PhantomJS 1.9.8 (Mac OS X 0.0.0) Service: OntologyService should return the object of ontologies FAILED
    Error: Unexpected request: GET http://ift.tt/28OCCiu
