如何对我的asp.net-mvc控制器的OnActionExecuting方法进行单元测试？

using Xunit;
using MyApp.Controllers;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
using System.Collections.Generic;
using System.Security.Claims;
using System.Threading.Tasks;

[Fact]
public void OnActionExecuting_Test()
{
    // Arrange
    var controller = new MyController();
    var actionContext = new ActionExecutingContext(
        new ActionContext(new DefaultHttpContext(), new RouteData(), new ControllerActionDescriptor()),
        new List<IFilterMetadata>(),
        new Dictionary<string, object>(),
        new object());

    // Act
    controller.OnActionExecuting(actionContext);

    // Assert
    // Add assertions to check if the OnActionExecuting method worked as expected
}
