asp.net-mvc-4 – 单元测试 – httpcontext为null,websecurity.CurrentUserId未填充

我有一个MVC 4应用程序,我正在构建单元测试.在我的GameController中,我有一个Action,JoinGame,它需要当前的userid.我在控制器内部使用WebSecurity.CurrentUserId.

当我为JoinGame运行单元测试时,没有填充UserId.显然,在单元测试期间,没有“当前”用户.我正在试图弄清楚如何模仿一个.

我得到的第一个错误是System.ArgumentNullException:Value不能为null.参数名称;的HttpContext

>经过多次搜索,我找到了
How to mock httpcontext so that it is not null from a unit test?.

我按照该链接中的指导(创建了一个HttpContextFactory,
它模拟了httpcontext并设置了当前的控制器上下文
对模拟的数据).这没有任何影响.

然后我找到了这个Mocking WebSecurity provider

我创建了一个包装器界面& websecurity的类,并嘲笑包装器&将websecuritywrapper注入游戏控制器.这解决了httpContext(虽然我现在并不真正理解为什么这样做而且HttpContextFactory没有),但是websecuritywrapper返回的CurrentUserId总是为0.即使我将它硬编码为1内部websecuritywrapper类(public int CurrentUserId) {get {return 1;}}

显然我做错了什么,只是不确定是什么.我已经发布了单元测试代码,控制器和下面的包装器.

public RedirectToRouteResult JoinGame(int gameid)
    {
        //_wr is the websecuritywrapper
        int UserID =  _wr.CurrentUserId; //WebSecurity.CurrentUserId;            

        // get userteam for this user and this game
        UserTeam ut = _UserTeamRepository.GetUserTeam(userteamid:0, gameid: gameid, userid: UserID);
        int intUTID = 0;
        if (ut == null)
        {
            // no userteam found, create it
            OperationStatus opStatus = _UserTeamRepository.CreateUserTeam(UserID, gameid);
            if (opStatus.Status) intUTID = (int)opStatus.OperationID;
        }
        else {intUTID = ut.Id; }
        if (intUTID > 0)
        {
            return RedirectToAction("Index", "ViewPlayers", new { id = intUTID });
        }
        else
        {
            return RedirectToAction("Index", "Game");
        }           
    }

最佳答案 你硬编码1时你得到0的原因是因为这行:

Mock<IWebSecurityWrapper> mockWSW = new Mock<IWebSecurityWrapper>();

你得到的IWebSecurityWrapper的版本是一个模拟(因为你这样注入它).添加

mockSW.Setup(x=>x.CurrentUserId).Returns(1);

应该得到你需要的东西.因为我们现在告诉模拟器在被要求使用CurrentUserId时返回1

HttpContextFactory不起作用的原因是因为我见过的HttpContextFactory实现处理控制器上的属性,我怀疑你对HttpContext的依赖是在WebSecurity类本身内部,因此你需要包装器.
