如何在ASP.NET核心的单元测试中设置请求的查询字符串？

Install-Package Moq

public IActionResult MyAction()
{
    string queryStringValue = Request.Query["param"];
    // 其他逻辑代码
    return View();
}

// 引入必要的命名空间
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Moq;

// 单元测试方法
[Fact]
public void MyAction_ReturnsViewResult_WithQueryStringValue()
{
    // 创建Mock对象
    var httpContextMock = new Mock<HttpContext>();
    var httpRequestMock = new Mock<HttpRequest>();

    // 设置查询字符串参数
    httpRequestMock.SetupGet(r => r.Query["param"]).Returns("queryValue");

    // 设置HttpContext的Request属性
    httpContextMock.SetupGet(c => c.Request).Returns(httpRequestMock.Object);

    // 创建控制器实例
    var controller = new MyController();
    controller.ControllerContext.HttpContext = httpContextMock.Object;

    // 调用被测试的方法
    var result = controller.MyAction();

    // 断言
    var viewResult = Assert.IsType<ViewResult>(result);
    Assert.Equal("queryValue", viewResult.ViewData["param"]);
}
