对于我一生，我无法让$ httpBackend在执行$ http get请求的控制器上工作。我已经尝试了几个小时=）

我将其简化为下面可以最简单的形式。如果我通过测试

• 在控制器中注释掉$ http.get（）请求
• 在测试中注释掉“ httpMock.flush（）”
• 并更改“猪”和“狗”以匹配

也就是说，这是一个有效的工作测试和应用程序。

如果放回去，则会在底部显示错误。

app / js / app.js

// Declare a module which depends on filters and services.
var myApp = angular
  .module('myApp', ['ngRoute', 'myApp.filters', 'myApp.services',
                              'myApp.directives'])
  .config(['$routeProvider' , function($routeProvider) {

    $routeProvider
      .when("/dashboard", {
        templateUrl: "partials/dashboard.html",
        controller: cDashboard
      })

      .otherwise({redirectTo: "/dashboard"});
  }]);

// Pre-define our main namespace modules.
angular.module('myApp.directives' , []);
angular.module('myApp.filters'    , []);
angular.module('myApp.services'   , []);
angular.module('myApp.controllers', []);

app / js / controller.js

function cDashboard ($scope, $http) {
  $scope.data = "dog";

  // Fetch the actual data.
  $http.get("/data")
    .success(function (data) { $scope.data = data })
    .error(function () {});
}

cDashboard.$inject = [ '$scope', '$http' ];

测试/单位/控制器Spec.js

describe('cDashboard', function(){
  var scope, ctrl, httpMock;

  beforeEach(inject(function ($rootScope, $controller, $http, $httpBackend) {
    scope = $rootScope.$new();
    ctrl = $controller('cDashboard', {$scope: scope});

    httpMock = $httpBackend;
    httpMock.when("GET", "/data").respond("pig");
  }));

  it("should get 'pig' from '/data'", function () {
    httpMock.expectGET("/data").respond("pig");
    expect(scope.data).toBe("pig");
  });

});

这是我在shell中得到的错误：
