I am currently trying to test a service that utilizes Restangular, but I am facing difficulties in creating the correct spy on chained promises.
var services = angular.module('services.dashboards', ['models.dashboards', 'models.metrics', 'LocalStorageModule', 'app.filters']);
services.factory('DashboardsService', ['Restangular', '$q', 'Metrics', 'Dashboards', 'localStorageService', '$filter', 'filterByGradedFilter', function (Restangular, $q, Metrics, Dashboards, localStorageService, $filter, filterByGradedFilter) {
var factory = {};
factory.getData = function () {
var defer = $q.defer();
var data = localStorageService.get('data');
if (!data) {
Dashboards.post()
.then(function (result) {
return Restangular.oneUrl('newDash', result.data).get();
})
.then(function (result) {
data = result.data;
localStorageService.set('data', data);
defer.resolve(data);
});
} else {
defer.resolve(data);
}
return defer.promise;
}
return factory;
}]);
The specific chained promise that I am attempting to test is:
Dashboards.post()
.then(function (result) {
return Restangular.oneUrl('newDash', result.data).get();
})
.then(function (result) {
data = result.data;
localStorageService.set('data', data);
defer.resolve(data);
});
While the test is executing, I am encountering an error:
Error: get() method does not existdescribe('Dashboards Service', function () {
// Holds the service under test
var service;
// Dependencies
var dashboards;
var restangular;
var q;
var rootScope;
beforeEach(module('services.dashboards'));
// We inject the service
beforeEach(inject(function (_DashboardsService_, _Dashboards_, _Restangular_, _$q_, _$rootScope_) {
service = _DashboardsService_;
dashboards = _Dashboards_;
restangular = _Restangular_;
q = _$q_;
rootScope = _$rootScope_
}));
describe('#getData', function ($rootScope) {
it('should get a dashboard', function () {
spyOn(dashboards, 'post').and.returnValue(q.when({}));
// Tried that but it's not working
spyOn(restangular, 'oneUrl').and.callFake(function() {
return this;
// Also tried return restangular;
});
spyOn(restangular, 'get').and.returnValue(q.when({}));
service.getData().then(function (result) {
expect(result).toEqual({});
});
expect(dashboards.post).toHaveBeenCalled();
expect(restangular.oneUrl).toHaveBeenCalledWith('newDash');
expect(restangular.oneUrl.get).toHaveBeenCalled();
rootScope.$apply();
})
})
})
