我有一个web服务,我试图单元测试。在服务中,它从HttpContext中提取了几个值,如下所示:

 m_password = (string)HttpContext.Current.Session["CustomerId"];
 m_userID = (string)HttpContext.Current.Session["CustomerUrl"];

在单元测试中,我使用一个简单的工作请求创建上下文,如下所示:

SimpleWorkerRequest request = new SimpleWorkerRequest("", "", "", null, new StringWriter());
HttpContext context = new HttpContext(request);
HttpContext.Current = context;

然而,每当我试图设置HttpContext.Current.Session的值时

HttpContext.Current.Session["CustomerId"] = "customer1";
HttpContext.Current.Session["CustomerUrl"] = "customer1Url";

我得到空引用异常,说HttpContext.Current.Session是空的。

是否有方法在单元测试中初始化当前会话?


当前回答

在asp.net Core / MVC 6 rc2中,你可以设置HttpContext

var SomeController controller = new SomeController();

controller.ControllerContext = new ControllerContext();
controller.ControllerContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

Rc 1为

var SomeController controller = new SomeController();

controller.ActionContext = new ActionContext();
controller.ActionContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

考虑使用Moq

new Mock<ISession>();

对我有效的答案是@Anthony写的,但你必须加上另一行 请求。SetupGet(req => req. headers)。返回(新NameValueCollection ()); 所以你可以用这个: HttpContextFactory.Current.Request.Headers。Add(关键字,值);

如果您正在使用MVC框架,这应该可以工作。我使用Milox的FakeHttpContext并添加了一些额外的代码行。这个想法来自这个帖子:

http://codepaste.net/p269t8

这似乎在MVC 5中工作。我还没有尝试在早期版本的MVC。

HttpContext.Current = MockHttpContext.FakeHttpContext();

var wrapper = new HttpContextWrapper(HttpContext.Current);

MyController controller = new MyController();
controller.ControllerContext = new ControllerContext(wrapper, new RouteData(), controller);

string result = controller.MyMethod();

Milox解决方案比IMHO接受的解决方案更好,但我在处理url时遇到了一些问题。

我做了一些改变,使它能正常工作与任何url和避免反射。

public static HttpContext FakeHttpContext(string url)
{
    var uri = new Uri(url);
    var httpRequest = new HttpRequest(string.Empty, uri.ToString(),
                                        uri.Query.TrimStart('?'));
    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);

    return httpContext;
}

你可以试试FakeHttpContext:

using (new FakeHttpContext())
{
   HttpContext.Current.Session["CustomerId"] = "customer1";       
}

我找到了以下在HttpContext中指定用户的简单解决方案:https://forums.asp.net/post/5828182.aspx
