如何使用 session 存储和 cookies 检索和存储值的操作来模拟 controller？

Question

我目前正在对 mocking 称为 ResourcesCustomReports 的 controller 操作方法进行单元测试，它是 controller。

action 方法调用一个名为 GetCurrentTenant 的辅助方法，该方法使用 this.Request.Cookies["selectedtenant"] 返回一个值。

在操作中，我还使用 session 存储来存储键值对。 我的问题是如何连接/模拟此操作方法？ 自动柜员机我收到此错误：

System.NullReferenceException：“对象引用未设置为 object 的实例。”

Microsoft.AspNetCore.Mvc.ControllerBase.Request.get 返回 null。

    protected Guid GetCurrentTenant()
    {
        var currentTenant = this.Request.Cookies["selectedtenant"] ?? 
        this.GetUserDefaultTenant().ToString();
        return Guid.Parse(currentTenant);
    }

    [TestMethod]
    public void GetCustomDateResourcesReturnsExcelWorkBook()
    {
        var mockPrismRepository = new Mock<IPrismRepository>();
        var mockIlogger = new Mock<ILogger<AzureReportsController>>();
        var mockReportsRepository = new Mock<IReportsRepository>();
        var context = new Mock<ControllerContext>();

        DateTime from = DateTime.Today;
        DateTime to = from.AddDays(30);

        var tenantId = Guid.Parse("3c6b60a7-8d30-4da3-bfdc-00691e899b5f");
        var excelWorkBook = new XLWorkbook();
        var mockReportRepository = new Mock<IReportsRepository>();

        mockReportRepository.Setup(r => r.GetCustomDateResources(tenantId,
        to, from)).Returns(excelWorkBook);
        var azureReportControllerUnderTest = new 
        AzureReportsController(mockIlogger.Object, 
        mockPrismRepository.Object, mockReportRepository.Object);

        azureReportControllerUnderTest.ControllerContext = new ControllerContext
        {
            HttpContext = new DefaultHttpContext(),
        };
        azureReportControllerUnderTest.ControllerContext = context.Object;

        var result = azureReportControllerUnderTest.ResourcesCustomReports(to, from);
        Assert.IsNotNull(result);

        excelWorkBook.Dispose();
        azureReportControllerUnderTest.Dispose();
    }

    protected Guid GetCurrentTenant()
    {
     var currentTenant = this.Request.Cookies["selectedtenant"] ? 
     this.GetUserDefaultTenant().ToString();
     return Guid.Parse(currentTenant);
    }


   public IActionResult ResourcesCustomReports(DateTime? startingDate, 
   DateTime endingDate)
    {
        var selectedTenant = this.GetCurrentTenant();
        var fileName = $"resources_report_tenant_id_{selectedTenant}.xlsx";
        var workbook = 
        this.reportsRepository.GetCustomDateResources(selectedTenant, startingDate, 
        endingDate);
        string handle = Guid.NewGuid().ToString();

        using (MemoryStream memoryStream = new MemoryStream())
        {
            workbook?.SaveAs(memoryStream);
            memoryStream.Position = 0;
            this.HttpContext.Session.Set(handle, memoryStream.ToArray());
        }

        return this.Json(new { FileGuid = handle, FileName = fileName });
    }
