在方法单元测试中，如何获得分配给受保护对象的HttpContext.Current.Server.MapPath的伪路径？

// 引入相关命名空间
using Moq;
using System.Web;

// 创建HttpContext的模拟对象
var httpContextMock = new Mock<HttpContextBase>();

// 创建HttpRequest的模拟对象
var httpRequestMock = new Mock<HttpRequestBase>();

// 创建HttpServerUtility的模拟对象
var httpServerUtilityMock = new Mock<HttpServerUtilityBase>();

// 设置HttpRequest的物理路径
httpRequestMock.Setup(r => r.MapPath(It.IsAny<string>())).Returns("fake/path");

// 将模拟的HttpRequest对象设置到模拟的HttpContext对象中
httpContextMock.SetupGet(c => c.Request).Returns(httpRequestMock.Object);

// 将模拟的HttpServerUtility对象设置到模拟的HttpContext对象中
httpContextMock.SetupGet(c => c.Server).Returns(httpServerUtilityMock.Object);

// 获取伪路径
var fakePath = httpContextMock.Object.Server.MapPath("relative/path");

// 打印伪路径
Console.WriteLine(fakePath);
