在不嘲讽的情况下测试测试项目中的视图

如何在不使用mocking的情况下从测试项目中测试视图？我试过各种各样的东西。通过MarshalByRefObject并使用其ViewToString方法生成ASP.NET应用程序主机。我还尝试过动态实例化ViewPage对象，但没有成功。

Test method Fablelane.WebApplication.Tests.UseCases.CreateNewSchoolAsAdministrator threw exception: 
System.NullReferenceException: Object reference not set to an instance of an object.

这个错误发生在我使用实例化方法的时候。

当我尝试执行应用程序主机解决方案时，它失败了，并出现序列化异常，表示无法序列化属性。

我被卡住了——该怎么办？
