c# - 在不模拟的情况下测试测试项目的 View ？

Question

如何在不使用模拟的情况下从我的测试项目中测试我的 View ？我尝试过各种各样的事情。通过 MarshalByRefObject 并使用其 ViewToString 方法制作 ASP .NET 应用程序宿主。我也试过动态实例化一个 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.

那个错误是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，它失败并出现序列化异常，指出属性无法序列化。

我被卡住了 - 怎么办？

您的 View 位于您的 UI 层中，您只需对 UI 层进行单元测试，模拟从服务层到您的 Controller / View 正在使用的所有内容。

您的 UI 层不需要集成测试，因为您的测试团队会测试您的用例(功能)是否已正确实现，如果页面无法加载，您就会知道。

您的业务逻辑通常位于单独的层中，例如您的服务层。 这是集成测试最常见的地方，在您的服务和数据层之间。

与其尝试解决环境问题，不如坚持做有效的事情？ UI 层和单元的单元测试以及服务层的集成测试。

除了自动浏览器测试，您还可以使用类似 Selenium 的东西或类似的。
