Loading a mock JSON file within Karma+AngularJS test

Question

I have an AngularJS app set up with tests using Karma+Jasmine. I have a function I want to test that takes a large JSON object, converts it to a format that\'s more consumab

Answer 1

Here is an alternative to Cameron's answer, without the need for jasmine-jquery nor any extra Karma config, to test e.g. an Angular service using $resource :

angular.module('myApp').factory('MyService', function ($resource) {
    var Service = $resource('/:user/resultset');
    return {
        getResultSet: function (user) {
            return Service.get({user: user}).$promise;
        }
    };
});

And the corresponding unit test :

describe('MyServiceTest', function(){
    var $httpBackend, MyService, testResultSet, otherTestData ;

    beforeEach(function (done) {
        module('myApp');
        inject(function ($injector) {
            $httpBackend = $injector.get('$httpBackend');
            MyService = $injector.get('MyService');
        });
        // Loading fixtures
        $.when(
            $.getJSON('base/test/mock/test_resultset.json', function (data) { testResultSet = data; }),
            $.getJSON('base/test/mock/test_other_data.json', function (data) { otherTestData = data; })
        ).then(done);
    });

    it('should have some resultset', function() {
        $httpBackend.expectGET('/blahblahurl/resultset').respond(testResultSet);
        MyService.getResultSet('blahblahurl').then(function (resultSet) {
            expect(resultSet.length).toBe(59);
        });
        $httpBackend.flush();
    });
});
