我想对我的控制器进行单元测试。我从expect API 的基本测试断言开始。但是我在条件检查中模拟范围方法时面临挑战。我收到一个undefined错误，因为它在范围内不可用，只有全局logout()方法可用。
我尝试将localStorageServiceusing模拟spyOn为 true 以满足条件，但这仍然无济于事。任何解决方案都会对我启动有很大帮助。
控制器：
angular.module('app').controller('sampleCtrl',
function($scope, $state, $http, $rootScope, localStorageService) {
if (!(localStorageService.get('isAuthenticated'))) {
$state.go('home');
}
if (localStorageService.get('isAuthenticated') === true) {
//http post calls made here to perform certain operation on page load
$scope.someMethod = function(){
//do something
}
}
$scope.logOut = function() {
localStorageService.set('property', '');
localStorageService.set('isAuthenticated', false);
$state.go('home');
};
});
业力：
'use strict';
describe('Controller: sampleCtrl', function() {
/** to load the controller's module */
beforeEach(module('app'));
var sampleCtrl,scope,httpBackend,deferred,rootScope;
beforeEach(inject(function ($controller,_$rootScope_,$httpBackend,$q) {
var store = {};
scope= _$rootScope_.$new(); // creates a new child scope of $rootScope for each test case
rootScope = _$rootScope_;
localStorageService = _localStorageService_;
httpBackend = $httpBackend;
httpBackend.whenGET(/\.html$/).respond('');
spyOn(localStorageService, 'set').and.callFake(function (key,val) {
store[key]=val;
});
spyOn(localStorageService, 'get').and.callFake(function(key) {
return store[key];
});
sampleCtrl = $controller('sampleCtrl',{
_$rootScope_:rootScope,
$scope:scope,
$httpBackend:httpBackend,
_localStorageService_:localStorageService
// add mocks here
});
localStorageService.set('isAuthenticated',true);
}));
/**ensures $httpBackend doesn’t have any outstanding expectations or requests after each test*/
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it('sampleCtrl to be defined:',function(){
httpBackend.flush();
expect(sampleCtrl).toBeDefined();
});
// failing test case - scope.someMethod not available in scope
it('is to ensure only authenticated user can access the state methods',function(){
localStorageService.get('isAuthenticated');
httpBackend.flush();
expect(scope.someMethod).toBeDefined();
});
});
