Asp.net mvc 3 httpcontext.current.server.mappath和单元测试

我将asp.net mvc3/razor与dbfirst模型一起使用。 我在注册后以xml格式发送确认电子邮件。 我需要在单元测试时读取这个xml文件， 由于httpcontext.current为null，我得到了null引用错误。我试图模拟它，但再次得到一个错误，说“值不能为null” 这是我的代码，请帮助：

会计控制员：

  Fds.ReadXml(HttpContext.Current.Server.MapPath("~/Files/ForgotPassword.xml"));

单元测试：

 public void Saveuser()
         {
             RegisterModel model = new RegisterModel();
             FormCollection f = new FormCollection();
             List<MailModel> m = new List<MailModel>();
             HttpContext.Current = FakeHttpContext();
             m = user.GetMail().ToList();
             MailModel mmodel = new MailModel();
             mmodel = m[0];
           model.Name = "testuse11r9788";
          model.UserName = "test1user9878";
          model.Password = "1234567";
          model.ConfirmPassword = "1234567";
          model.Email = "testus11979@gmail.com";
          var controller = new AccountController(user,mail);
          var saveuser = controller.Register(model,f) as ViewResult;
          var saveActUser = (RegisterModel)saveuser.ViewData.Model;
          var saveExpUser = model;
           areuserEqual(saveExpUser, saveActUser);
         }

public static HttpContext FakeHttpContext()
        {

您需要抽象出XML文件的加载

例如,

class WebContentLocator : IContentLocator{
    public string GetPath(string relativePath) {
         return HttpContext.Current.Server.MapPath(relativePath);
    }
}

class TestContentLocator : IContentLocator{
    string _contentRoot;
    public TestContentLocator() {
         _contentRoot = ConfigurationManager.AppSettings["ContentRoot"];
    }

    public string GetPath(string relativePath) {
         return Path.Combine(_contentRoot,  relativePath.Replace("~", string.empty);
    }
}

interface IContentLocator {
    string GetPath(string relativePath);
}

在测试中，将TestContentLocator注入到执行XML加载的代码中，默认情况下使用WebContentLocator

Fds.ReadXml(_contentLocator.Get("~/Files/ForgotPassword.xml"));
