angularjs - createSpy 如何在 Angular + Jasmine 中工作？

Question

我做了一个工厂的简单演示，我正在尝试使用 来测试它。 Jasmine .我能够运行测试，但我使用的是 spy 方法。我宁愿使用 Jasmine .createSpy 或 jasmine.createSpyObj 做同样的测试。有人可以帮我重构我的代码，以便在我的示例中使用这些方法吗？

describe('value check',function(){
  var $scope,
  ctrl,
  fac;
  beforeEach(function(){
    module('app');

  });

beforeEach(inject(function($rootScope,$controller,appfactory) {
    $scope = $rootScope.$new();  
     ctrl = $controller('cntrl', {$scope: $scope});
     fac=appfactory;
     spyOn(fac, 'setValue');
     fac.setValue('test abc');
}));


  it('test true value',function(){
    expect(true).toBeTruthy()
  })

   it('check message value',function(){
    expect($scope.message).toEqual(fac.getValue())
  })

   it("tracks that the spy was called", function() {
    expect(fac.setValue).toHaveBeenCalled();
  });

  it("tracks all the arguments of its calls", function() {
    expect(fac.setValue).toHaveBeenCalledWith('test abc');
  });
})

更新

angular.module('app',[]).factory('appfactory',function(){
  var data;
  var obj={};
  obj.getValue=getValue;
  obj.setValue=setValue;

  return obj;

  function getValue(){
   return data; 
  }

  function setValue(datavalue){
    data=datavalue;
  }

}).controller('cntrl',function($scope,appfactory){
  appfactory.setValue('test abc');
  $scope.message=appfactory.getValue()
})

我已经换了你的 plunkr :

 spy = jasmine.createSpy('spy');

 fac.setValue = spy;

编辑

In Jasmine, mocks are referred to as spies. There are two ways to create a spy in Jasmine: spyOn() can only be used when the method already exists on the object, whereas jasmine.createSpy() will return a brand new function.
