在HttpSessionStateBase中獲取null c＃單元測試

Question

運行我的單元測試方法時，我在HttpSessionStateBase的實例中獲取了空值。我曾經嘲笑像這樣

var httpRequest = new HttpRequest("", "http://localhost/", ""); 
var stringWriter = new StringWriter(); 
var httpResponse = new HttpResponse(stringWriter); 
var httpContext = new HttpContext(httpRequest, httpResponse); 
var sessionContainer = new HttpSessionStateContainer("id", 
                new SessionStateItemCollection(), 
                new HttpStaticObjectsCollection(), 
                10, 
                true, 
                HttpCookieMode.AutoDetect, 
                SessionStateMode.InProc, 
                false); 

SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer); 

的HttpContext請提出了一些想法，讓在HttpSessionStateBase一些虛擬值

讓我們假設你有你需要的單元測試下面的控制器操作：

public class AccountController: Controller 
{ 
    public ActionResult Login(Customer obj) 
    { 
     Session.Clear(); 
     return View(); 
    } 
} 

，這裏是一個樣本線了：

// arrange 
var httpRequest = new HttpRequest("", "http://localhost/", ""); 
var stringWriter = new StringWriter(); 
var httpResponse = new HttpResponse(stringWriter); 
var httpContext = new HttpContext(httpRequest, httpResponse); 
var sessionContainer = new HttpSessionStateContainer(
    "id", 
    new SessionStateItemCollection(), 
    new HttpStaticObjectsCollection(), 
    10, 
    true, 
    HttpCookieMode.AutoDetect, 
    SessionStateMode.InProc, 
    false); 
SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer); 

var controller = new AccountController(); 
var requestContext = new RequestContext(new HttpContextWrapper(httpContext), new RouteData()); 
controller.ControllerContext = new ControllerContext(requestContext, controller); 

// act 
var actual = controller.Login(new Customer()); 

// assert 
... 

公告您需要在調用操作之前填充controller.ControllerContext屬性。
