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
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。我正在试图弄清楚如何嘲笑一个。
我得到的第一个错误是System.ArgumentNullException: Value cannot be null. Parameter name; 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)。 这没有任何效果。
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({{1 }}
显然我做错了什么,只是不确定是什么。我已经为单元测试,控制器和下面的包装器发布了代码。
public int CurrentUserId{ get { return 1; }}
的
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");
}
}
的
[Test]
public void Game_JoinGame_Returns_RedirectToAction()
{
UserProfile creator = new UserProfile();
UserProfile user = new UserProfile();
Game game = new Game();
ICollection<UserTeam> uteams = null;
UserTeam ut = new UserTeam();
ICollection<UserTeam_Player> utp = null;
List<Game> games = new List<Game>
{
new Game { Id = 1, CreatorId = 1, Name = "Game1", Creator = creator, UserTeams=uteams},
};
List<UserTeam> userteams = new List<UserTeam>
{
new UserTeam {Id=1, UserId = 1, GameId=1, User=user, Game = game, UserTeam_Players=utp}
};
Mock<IGameRepository> mockGameRepository = new Mock<IGameRepository>();
Mock<IUserTeamRepository> mockUserTeamRepository = new Mock<IUserTeamRepository>();
Mock<IWebSecurityWrapper> mockWSW = new Mock<IWebSecurityWrapper>();
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
GameController Controller = new GameController(mockGameRepository.Object, mockUserTeamRepository.Object, mockWSW.Object);
// This didn't work
//HttpContextFactory.SetFakeAuthenticatedControllerContext(Controller);
//Act
RedirectToRouteResult result = Controller.JoinGame(1);
Assert.AreEqual("Index", result.RouteValues["action"]);
}
答案 0 :(得分:2)
当你硬编码1时,你回来0的原因是因为这一行:
Mock<IWebSecurityWrapper> mockWSW = new Mock<IWebSecurityWrapper>();
你得到的IWebSecurityWrapper的版本是一个模拟(因为你注入了它)。添加
mockSW.Setup(x=>x.CurrentUserId).Returns(1);
应该得到你所需要的。因为我们现在告诉模拟器在被要求使用CurrentUserId时返回1
HttpContextFactory无法工作的原因是因为我已经看到HttpContextFactory实现处理控制器上的属性而我怀疑你对HttpContext的依赖是在WebSecurity类本身内部,因此你需要包装器。
