Angularjs 角isn中的业力测试'；I don’’我不会做人们期望做的事

我的登录控制器是：

angular.module('mean').controller('LoginController', ['$scope', '$location', '$rootScope', 'UserService', function ($scope, $location, $rootScope, UserService) {
  $scope.init = function() {
    $scope.credentials = {};
    $scope.status_object = {
      text: '',
      class: '',
      show: false
    };    
  }

  $scope.authenticate = function() {
    $scope.status_object = {
      text: 'Authenticating...',
      class: 'info',
      show: true
    };
    UserService.authenticate($scope.credentials).then(function(response) {
      if(response.data.status === 'error') {
        $scope.status_object = {
          text: response.data.error,
          class: 'danger',
          show: true
        };
      } else if(response.data.status === 'ok') {
        $rootScope.globals.logged_in = true;
        $location.path('/' + response.data.user.access);
      }
    });
  };
}]);

我的测试是：

  describe('LoginController', function() {
    beforeEach(module('mean'));

    var scope, rootScope, LoginController, $httpBackend, $location;

    beforeEach(inject(function($controller, $rootScope, _$httpBackend_, _$location_) {
      scope = $rootScope.$new();
      rootScope = $rootScope.$new();

      LoginController = $controller('LoginController', {
        $scope: scope,
        $rootScope: rootScope
      });

      $httpBackend = _$httpBackend_;

      $location = _$location_;
    }));

    it('should show danger when wrong credentials are used', function() {
      scope.credentials = {
        email: 'test@email.com',
        password: 'password'
      }

      $httpBackend.expectPOST('/api/v1/user/auth').respond({
        status: 'error',
        error: 'Invalid User'
      });

      console.log(scope.status_object);
      scope.authenticate();
      $httpBackend.flush();


      expect(scope.status_object).toEqualData({text: 'Invalid User', class: 'danger', show: true});
    });
  });

在我看来，我有一个

ng init=“init（）”

。前端的一切工作都很顺利，但在运行测试时，我得到：

PhantomJS 1.9.7 (Mac OS X) LoginController should show danger when wrong credentials are used FAILED
  TypeError: 'undefined' is not a function (evaluating 'expect(scope.status_object).toEqualData({text: 'Invalid User', class: 'danger', show: true})')
      at /myapp/test/karma/unit/controllers/login.spec.js:43
PhantomJS 1.9.7 (Mac OS X): Executed 4 of 4 (1 FAILED) (0.135 secs / 0.043 secs)

我不确定我的测试出了什么问题。有什么想法吗？

结果是：

expect（scope.status\u object）.toEqualData（{text:'Invalid User'，class:'danger'，show:true}）导致了错误。没有
toEqualData
，所以我使用
toEqual
，它现在工作了结果是：
expect（scope.status\u object）。toEqualData（{text:'Invalid User'，class:'danger'，show:true}）导致了错误。没有
toEqualData
，因此我使用
toEqual
，它现在正在工作是的，您需要首先定义toEqualData，例如，它的工作方式：

  beforeEach(function(){
    this.addMatchers({
      toEqualData: function(expected) {
        return angular.equals(this.actual, expected);
      }
    });
  });
