Error occurs when comparing arrays in AngularJS using Jasmine testing framework

Having trouble testing the value of myArray after pushing data to it. Despite my efforts, I keep encountering an error indicating that the array content does not match my static arr variable. Could someone kindly review my code below and shed light on what mistake I might be making, causing Jasmine to report the two arrays as unequal? Thank you.

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[]"]

  });

The toBe() function compares objects using ===, requiring them to be exact matches in both value and type. Perhaps you should consider testing with

expect(scope.myArray).toEqual(arr);
