单元测试没有给出grunt dev-test检查的预期错误

Question

我正在尝试开始运行单元测试，同时使用grunt dev-test来学习MEAN来检查以下内容，这应该会返回错误。但是，终端grunt dev-test会将文件检测为已更改，并且不会报告任何错误。

'use strict';

describe('appMyDirective', function() {
    var elm, elmScope, $scope, $compile, $timeout;

beforeEach(module('myApp'));

/**
@param params
    @param {String} html
*/
var createElm =function(params) {
    var html ="<div app-my-directive>"+
    "</div>";
    if(params.html) {
        html =params.html;
    }
    // elm =angular.element(html);
    elm =$compile(html)($scope);
    // $scope.$digest();
    $scope.$apply();        //NOTE: required otherwise the alert directive won't be compiled!!!! ... wtf?
    elmScope =elm.isolateScope();
    var elements ={
        // 'somePart':elm.find('div').children().find('div')
    };
    return elements;
};

beforeEach(inject(function(_$rootScope_, _$compile_, _$timeout_) {
    $compile = _$compile_;
    $timeout = _$timeout_;
    $scope = _$rootScope_.$new();
}));

// afterEach(function() {
// });


it('should have a scopeOne property', function() {
    $scope.scopeOne ='test scope one';
    var html ="<div app-my-directive scope-one='scopeOne'></div>";
    createElm({html:html});
    expect(elmScope).toBe('test scope one1');
    });
});

自$scope.scopeOne ='test scope one';和expect 'test scope one1'以来，这不应该通过，因为它是“不可靠的”。或者我在这里做错了什么？

指令代码：

请提供指令代码，因为现在我们已经“预期未定义为'测试范围one1'。” - 随意使用“运行代码段”执行测试

angular.module('myApp', [])

describe('appMyDirective', function() {
  var elm, $scope, $compile;

  beforeEach(module('myApp'));

  var createElm = function(params) {
    var html = "<div app-my-directive>" +
      "</div>";
    if (params.html) {
      html = params.html;
    }
    elm = $compile(html)(params.scope);
    params.scope.$apply(); //NOTE: required otherwise the alert directive won't be compiled!!!! ... wtf?
    return elm.isolateScope();
  };

  beforeEach(inject(function(_$rootScope_, _$compile_) {
    $compile = _$compile_;
    $scope = _$rootScope_.$new();
  }));

  it('should have a scopeOne property', function() {
    $scope.scopeOne = 'test scope one';

    var elmScope = createElm({
      html: "<div app-my-directive scope-one='scopeOne'></div>",
      scope: $scope
    });

    expect(elmScope).toBe('test scope one1');
  });
});
