asp.net-mvc - 谁能给我展示一些用于测试控制器（以及 MVC 站点的其他方面）的 NSpec 示例？

Question

我开始使用 NSpec，但希望能获得一些关于使用它来规范或测试我的控制器的正确方法的建议。基本上几个例子会有很长的路要走。有没有示例项目？所有帮助将不胜感激。

理查德。

为什么是！下面的测试套件来自参考实现，有 4 个独特的 mvc 应用程序都使用 NSpec 作为他们的测试套件。一定要在这里看看。

这是其中一项测试。本规范验证登录页面和注册页面。对于一个网站。

using System;
using System.Linq;
using NSpec;
using BorrowedGames.Controllers;

using System.Collections.Generic;

namespace BorrowedGames.Tests.Controllers

  class describe_AccountController : _borrowed_games
  {
    AccountController controller;

    dynamic user;

    bool authenticated;

    void before_each()
    {
      controller = new AccountController();

      controller.Authenticate = s =>
      {
        authenticated = true;

        SetCurrentUser(controller, Users.ForEmail(s).Id);
      };
    }

    void logging_in()
    {
      context["requesting login page"] = () =>
      {
        act = () => result = controller.LogOn();

        it["returns login page"] = () => 
          (result as object).should_cast_to<ViewResult>();
      };

      context["authenticating"] = () =>

        context["user name is taken"] = () =>

        };
