javascript - AngularJS Jasmine 比较数组返回错误

Question

我试图在将数据推送到 myArray 后测试其值，但总是收到数组内容不等于我的静态 arr var 的错误。有人可以检查我下面的代码，让我知道我到底做错了什么以及为什么 Jasmine 报告两个数组不相等吗？谢谢

describe('Controller: MainCtrl', function () {

  var MainCtrl, scope;

  beforeEach(module('myApp'));

  beforeEach(inject(function ($controller, $rootScope) {
    scope = $rootScope.$new();
    MainCtrl = $controller('MainCtrl', {
      $scope: scope
    });
  }));

  it('Final ordered array of equation elements', function () {
      var arr = ["1", "2", "3", ".test[]"];
      expect(scope.myArray).toBe(arr);    
  });    


});



angular.controller('MainCtrl', function MainCtrl($scope) {

    $scope.myArray = [];
    $scope.myStr = '123.test[]';

    $scope.myArray.push($scope.myStr.slice(0,1), 
                            $scope.myStr.slice(1,2),
                            $scope.myStr.slice(2,3),
                            $scope.myStr.slice(3));
    console.log(myArray); //returns ["1", "2", "3", ".test[]"]

  });

toBe() 与 === 进行比较，这意味着它们需要是相同的对象而不仅仅是相同的值。您是否尝试过 expect(scope.myArray).toEqual(arr);
