我无法找出以下错误的解决方案

Question

我的test_Spec.js

代码

describe('Myctrl', function() {

   var $httpBackend, scope, createController, authRequestHandler;

   // Set up the module  
   beforeEach(module('myApp'));


    beforeEach(inject(function($injector) {
     // Set up the mock http service responses

     $httpBackend = $injector.get('$httpBackend');

     // backend definition common for all tests

     authRequestHandler = $httpBackend.when('GET', 'http://www.w3schools.com/angular/customers.php')
                            .respond(true);

     // Get hold of a scope (i.e. the root scope)

     $rootScope = $injector.get('$rootScope');

     // The $controller service is used to create instances of controllers
     var $controller = $injector.get('$controller');


     createController = function() {

       return $controller('Myctrl', {'$scope' : scope});

     };

   })

);


   afterEach(function() {

     $httpBackend.verifyNoOutstandingExpectation();

     $httpBackend.verifyNoOutstandingRequest();


   });

   it('should fetch authentication token', function() {
     $httpBackend.expectGET('http://www.w3schools.com/angular/customers.php');


     var controller = createController();

     expect(scope.names).toBe(true); 

     $httpBackend.flush();

   });


});

这是我的test.js服务电话

var myApp = angular.module('myApp', []);
  app.controller('Myctrl', function($Scope, $http) {
        $http.get("http://www.w3schools.com/angular/customers.php")
       .success(function(response) {$Scope.names = response.records;});

 });

和these是我得到的错误：

以下是错误摘要：

Error: [$injector:unpr] Unknown provider: $rootScopeProvider <- $rootScope <- $httpBackend http://errors.angularjs.org/1.2.0/$injector/unpr?p0=%24rootScopeProvider%20%3C-%20%24rootScope%20%3C-%20%24httpBackend

TypeError: Cannot read property 'expectGET' of undefined

TypeError: Cannot read property 'verifyNoOutstandingExpectation' of undefined

错误的解决方案是什么？我尝试了几件事，但我无法弄清楚确切的解决方案。请协助。

Answer 1

您希望将依赖项中的拼写错误注入控制器。

将$Scope更改为$scope;）

至于测试中的错误，请尝试以这种方式注入服务：

beforeEach(inject(function (_$httpBackend_, _$rootScope_, _$controller_) {
   …

Answer 2

Well, I know it is too late to answer but in case anyone else stumbles upon similar error, you can try the following:

You never defined the scope variable. You just declared it. So it actually should be:

scope = $injector.get('$rootScope').$new();

Also note the $new(). For every new test case, (as a best practice) you should get a new scope.
