单元测试嘲弄问题 [英] Unit testing mocking problem

问题描述

下面是我试图测试的方法但是它失败了Employee.CurrentEmployee.IsManager这是一个从嵌套类中获取的布尔值，它依赖于会话，因此当我为此运行单元测试时它会失败，因为它有当我运行单元测试时没有创建会话所以我尝试模拟对象

below is the method i tried to test but it fails for Employee.CurrentEmployee.IsManager this is a boolean value being fetched from a nested class which is dependent on the session so when i run unit test for this it fails cause there is no session created while i am running unit test so i tried mocking the object

public ActionResult IndexCompleted(PlanModel model)
        {
            int PlanID = model.Plan.PlanID;
            ViewBag.Title = "Plan Number: " + PlanID;
            //Only managers can access the plans (the bride now works at the chapel)
            if ((PlanID == 387484 || PlanID == 765675 || PlanID == 872095 || PlanID == 900535) && !Employee.CurrentEmployee.IsManager)
            {
                return Content("Unauthorized");
            }
            return View(model);
        }

我的尝试：



i我正在尝试创建一个模拟对象，但却因为我没有界面而创建它

What I have tried:

i am trying to create a mock object butfailing to create it cause i don't have a interface

[Test]
        public void FetchingPlanModelObjectIfYouAreManagerElseUnauthorized()
        {
            PlanController planController = new PlanController();
            PlanModel planmodel = new PlanModel()
            {
                Plan = new LittleChapel.Plan()
                {
                    PlanID = 387484
                }
            };
            Mock<iemployee> objMock = new Mock<iemployee>();
            objMock.Setup(x => Employee.CurrentEmployee.IsManager).Returns(true);
            //objMock.SetupProperty(x => x.IsManager,true);
            //objMock.Setup(x=>x.IsManager).Returns(true);
            var plan = planController.IndexCompleted(planmodel) as ViewResult;
            Assert.AreEqual(planmodel, plan.ViewData.Model);
        }

推荐答案

你的控制器代码中有一些神奇的数字。为什么不在一些额外的课程中交换它，从而得到一些你可以模拟的界面。

例如

you have some magic numbers there in your controller code. Why don't you swap this out in some extra class, thereby you get some interface you can mock against.
e.g.

void Main()
{
	var a = new PlanAuthorizationProvider();
	var result = a.IsAuthorized(true, 387484);
	//result.Dump();   // this is for linqpad 
}

public interface IPlanAuthorizationProvider
{
  bool IsAuthorized(bool isManager, int planId);
}

public class PlanAuthorizationProvider : IPlanAuthorizationProvider
{
  public bool IsAuthorized (bool isManager, int planId)
  {
   // this goes in your app.config
   //  < appSettings >
   //    < add key = "managerOnlyPlanIds" value = "387484,765675,872095,900535" />
   //  </ appSettings >
   //string managerOnlyPlantIds = ConfigurationManager.AppSettings["managerOnlyPlanIds"];
   string managerOnlyPlanIds = "387484,765675,872095,900535";
   var listOfManagerOnlyPlanIds = 
          managerOnlyPlanIds.Split(',').Select(int.Parse).ToList();
   if (listOfManagerOnlyPlanIds .Contains(planId))
   {
     return isManager;
   }
   else
   {
     return true;
   }
 }	 
}
