如何在不使用模拟的情况下从我的测试项目中测试我的视图？我尝试过各种各样的事情。通过 MarshalByRefObject 并使用其 ViewToString 方法创建 ASP .NET 应用程序宿主。我也尝试过动态实例化 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.

at Fablelane.WebApplication.Tests.UseCases.CreateNewSchoolAsAdministrator() in UseCases.cs: line 226

该错误是当我使用实例化方法时。

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

我被困住了——该怎么办？

您的视图位于 UI 层中，您只需对 UI 层进行单元测试，模拟从服务层到控制器/视图使用的所有内容。

您的 UI 层不需要集成测试，因为您的测试团队测试您的用例（功能）是否正确实现会让您知道页面是否无法加载。

您的业​​务逻辑通常位于单独的层中，例如您的服务层。这是最常见的集成测试，位于您的服务和数据层之间。

与其尝试解决环境问题，为什么不坚持有效的方法？UI 层和单元的单元测试以及服务层的集成测试。

除了自动化浏览器测试，您还可以使用Selenium或类似的东西。
