由于预期的 cookie，模拟 httpContext 和会话的 nSubstitute 问题

Question

我有一个 MVC 应用程序，我试图在其中模拟我的家庭控制器，以便调用我的 controller.Index()。

问题出在我的 homeController 的构造函数上。这是实际代码：

 public HomeController(IHttpContextAccessor httpContext, IUserRepository<CompanyUser> userRepository, IAuthorisationChecks authorisationChecks) : base(httpContext, userRepository, authorisationChecks)
    {

    }

我的基地 class 有以下内容：

public  ControllerBase(IHttpContextAccessor httpContext,IUserRepository<CompanyUser> userRepository,IAuthorisationChecks authorisationChecks)
    {
        _authorisationChecks = authorisationChecks;
        _userRepository = userRepository;
        _httpContext = httpContext;

        var cookie = _httpContext.HttpContext.Request.Cookies["auth"];
        var userCookie = _authorisationChecks.UnencryptedCookieValue("userdata", cookie);

       var userDeserialised = JsonConvert.DeserializeObject<SignInModel>(userCookie);
            userDeserialised.SessionId = _httpContext.HttpContext.Session.Id;
        var loggedInUser = Task.Run(async () => await _userRepository.SignInAsync(userDeserialised)).Result;
        _httpContext.HttpContext.Session.SetCurrentUser(loggedInUser);

    }

在我的测试中我目前有：

[Fact]
    public void Index_Returns_Correct_View_Test()
    {
        // Arrange

        var httpRequest = Substitute.For<HttpRequest>();
        var session = Substitute.For<ISession>();
        var httpResponse = Substitute.For<HttpResponse>();
        var httpContext = Substitute.For<IHttpContextAccessor>();
        var userRepository = Substitute.For<IUserRepository<EvaluateUser>>();
        var authorisationChecks = Substitute.For<IAuthorisationChecks>();

        userRepository.SignInAsync(new SignInModel
        {
            EmailAddress = _configuration["user:emailAddress"],
            Password = _configuration["user:password"],
            UserName = _configuration["user:username"],
            SessionId = _configuration["user:sessionId"]
        });

        session.Id.Returns(_configuration["user:sessionId"]);

        httpContext.HttpContext.Request.Returns(httpRequest);
        httpContext.HttpContext.Session.Returns(session);
        httpContext.HttpContext.Response.Returns(httpResponse);


        var controller = new HomeController(httpContext, userRepository, authorisationChecks);

        // Act
        var result = controller.Index();

        // Assert
        Assert.NotNull(result);
    }

当我尝试运行测试时，它在 controllerBase 中尝试设置 userDeserialised.SessionID 的行上失败，因为 var cookie 是空的。我怎样才能将其模拟到我的测试中，以便我的测试能够通过？

Answer 1

您应该能够删除 cookie 内容，然后 _authorisationChecks 调用：

val authCookie = "my-cookie-content";
httpContext.HttpContext.Request.Cookies["auth"].Returns(authCookie);

val userCookie = "{ json serialised sign-in model here }";
_authorisationChecks.UnencryptedCookieValue("userdata", authCookie).Returns(userCookie);
