"HttpContext.Current.User" 为空，当通过单元测试方法访问时

Question

在我的方法中，我通过使用“HttpContext.Current.User”获取当前用户。像这样

public class Test
{
public UserPrincipal GetUserContext()
 {
   System.Security.Principal.IPrincipal user = HttpContext.Current.User;
   return user;
 }
}

在我这样访问的测试方法中，

[TestMethod()]
public void TestMethod()
{
Test objTest = new Test();
System.Security.Principal.IPrincipal user=objTest.GetUserContext()
}

虽然运行这个测试方法我有异常因为 "HttpContext.Current.User" 是空的

任何熟悉这个问题的人都可以。提前致谢。

此代码将创建假的 HttpContext：

    string UserName = "username";
    HttpContext.Current = new HttpContext(
                          new HttpRequest("", "http://tempuri.org", ""),
                          new HttpResponse(new StringWriter()));
    HttpContext.Current.User = new GenericPrincipal(
                               new GenericIdentity(UserName),new string[0]);

"HttpContext.Current.User" 为空，当通过单元测试方法访问时

"HttpContext.Current.User" is null, when it is access through unit test method
