我有一个正在为其构建单元测试的 MVC 4 应用程序。在我的 GameController 中，我有一个 Action，JoinGame，它需要当前的用户 ID。我WebSecurity.CurrentUserId在控制器内部得到了这个。
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。我试图弄清楚如何模拟一个。
我得到的第一个错误是System.ArgumentNullException: Value cannot be null. Parameter name; httpContext
经过大量搜索，我发现 如何模拟 httpcontext 使其在单元测试中不为空？.
我遵循了该链接中的指导（创建了一个 HttpContextFactory，它模拟了 httpcontext 并将当前控制器上下文设置为模拟数据）。 这没有任何效果。
然后我找到了这个Mocking WebSecurity 提供程序
我为 websecurity 创建了一个包装器接口和类，并模拟了包装器并将 websecuritywrapper 注入到游戏控制器中。这解决了 httpContext （虽然我现在不明白为什么它有效而 HttpContextFactory 没有），但是 websecuritywrapper 返回的 CurrentUserId 始终为 0。即使我将它硬编码为 websecuritywrapper 类的 1 个内部人员（public int CurrentUserId{ get { return 1; }}
显然我做错了什么，只是不确定是什么。我已经在下面发布了单元测试、控制器和包装器的代码。
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");
}
}

new UserTeam {Id=1, UserId = 1, GameId=1, User=user, Game = game, UserTeam_Players=utp}
};

mockUserTeamRepository.Setup(mr => mr.GetAllUserTeams()).Returns(userteams);
mockUserTeamRepository.Setup(mr => mr.GetUserTeam(0,1,1)).Returns(ut);
mockUserTeamRepository.Setup(mr => mr.CreateUserTeam(1, 1));
//Arrange

// This didn't work
//HttpContextFactory.SetFakeAuthenticatedControllerContext(Controller);
//Act
RedirectToRouteResult result = Controller.JoinGame(1);
Assert.AreEqual("Index", result.RouteValues["action"]);
