c# - 最小起订量模拟和跟踪 session 值

Question

我在使用最小起订量模拟返回 session 值集时遇到问题。使用以下内容

public class TestHelpers
{
 public long sessionValue = -1;
 public HttpContextBase FakeHttpContext()
 {

  var httpContext = new Mock<HttpContextBase>();
  var session = new Mock<HttpSessionStateBase>();
  httpContext.Setup(x => x.Session).Returns(session.Object);
  httpContext.SetupGet(x => x.Session["id"]).Returns(sessionValue);
  httpContext.SetupSet(x => x.Session["id"] = It.IsAny<long>())
        .Callback((string name, object val) =>
        {
           sessionValue = (long)val;
        });
  }
}

当我尝试获取外部使用的值时

var th = new TestHelpers();
HttpContextBase httpContext = th.FakeHttpContext();

做一些设置 Session["id"]

的事情

var sessionid = httpContext.Session["id"];

sessionid 结果是-1。但是我可以使用

获取设置的 session 值

th.sessionValue

怎么了？难道我不能简单地通过 Moq 返回设置值吗？

我需要停止回答我自己的问题。事实证明我需要像这样再次模拟 Session["id"] ...

httpContext.SetupSet(x => x.Session["id"] = It.IsAny<long>())
        .Callback((string name, object val) =>
        {
           sessionValue = (long)val;
           httpContext.SetupGet(x => x.Session["id"]).Returns(sessionValue);
        });
