c# – 如何测试ActionFilterAttribute – OnActionExecuted

public class ActionAuthorizationAttribute: ActionFilterAttribute 
{

  protected override void  OnActionExecuted(ActionExecutedContext filterContext)
  {
    filterContext.HttpContext.Response.Redirect("SecurityException");
  }
}

如何编写单元测试来测试任何具有此属性的操作将重定向到SecurityException.

我的尝试

[TestClass]
public class TestControllerResponse
{
  [TestMethod]
  public void TestPermissionAccepted()
  {
    var controller = new TestController();
    var result = controller.Index() as RedirectToRouteResult;
    Assert.IsNotNull(result);
    Assert.AreEqual("SecurityException",result.RouteValues["action"]);
  }
}

protected class TestController : Controller
{
  [ActionAuthorization]
  public ActionResult Index()
  {
    return RedirectToAction("UnfortunatelyIWasCalled");
  }

}

不幸的是,测试失败了.索引操作重定向到“WonderIWasCalled”而不是“SecurityException”.
