單元測試數據註解

Question

我已經加入數據標註爲模型，發現代碼，

public class DownloadInfo 
{ 
    [Required] 
    public string Name { get; set; } 

    [Required] 
    [Email] 
    public string Email { get; set; } 
} 

，我首先要給無效的電子郵件ID喜歡下面寫這個數據的註解單元測試。

[Test] 
    public void InvalidTestPost() 
    { 
     TestControllerBuilder builder = new TestControllerBuilder(); 
     DownloadController downloadController = builder.CreateController<DownloadController>(); 

     DownloadInfo downloadInfo = new DownloadInfo(); 
     downloadInfo.Email= "some invaild email"; 

     Assert.IsTrue(!downloadController.ModelState.IsValid); 
    } 

我該如何單元測試數據註釋？

一個顯而易見的老問題，但這裏有一個答案，如果有人在尋找靜物。

using System; 
using Microsoft.VisualStudio.TestTools.UnitTesting; 
using System.ComponentModel.DataAnnotations; 
using DataAnnotationsTesting; 

namespace UnitTest 
{ 
    [TestClass] 
    public class OurDataValidationClassShould 
    { 
     [TestMethod] 
     public void ReturnAnErrorIfAnEmailIsInvalid() 
     { 
      DownloadInfo downloadInfo = new DownloadInfo() 
      { 
       Email = "Invalid Email", 
       Name = "Name" 
      }; 

      Validator.ValidateObject(downloadInfo, new ValidationContext(downloadInfo, null, null) { MemberName = "Email" }); 
     } 
    } 
}
