我是新的xUnit与.NET核心。我试图运行测试的一个示例项目在VS 2022。这是我的测试类：

using DeskBooker.Core.Domain;
using DeskBooker.Core.Processor;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;
using Moq;
using System;
using System.Collections.Generic;
using Xunit;

namespace DeskBooker.Web.Pages
{
 public class BookDeskModelTests
 {
   private Mock<IDeskBookingRequestProcessor> _processorMock;
   private BookDeskModel _bookDeskModel;
   private DeskBookingResult _deskBookingResult;

   public BookDeskModelTests()
   {
     _processorMock = new Mock<IDeskBookingRequestProcessor>();

     _bookDeskModel = new BookDeskModel(_processorMock.Object)
     {
       DeskBookingRequest = new DeskBookingRequest()
     };

     _deskBookingResult = new DeskBookingResult
     {
       Code = DeskBookingResultCode.Success
     };

     _processorMock.Setup(x => x.BookDesk(_bookDeskModel.DeskBookingRequest))
      .Returns(_deskBookingResult);
   }

   [Theory]
   [InlineData(1, true)]
   [InlineData(0, false)]
   public void ShouldCallBookDeskMethodOfProcessorIfModelIsValid(
     int expectedBookDeskCalls, bool isModelValid)
   {
     // Arrange
     if (!isModelValid)
     {
       _bookDeskModel.ModelState.AddModelError("JustAKey", "AnErrorMessage");
     }

     // Act
     _bookDeskModel.OnPost();

     // Assert
     _processorMock.Verify(x => x.BookDesk(_bookDeskModel.DeskBookingRequest),
       Times.Exactly(expectedBookDeskCalls));
   }

   [Fact]
   public void ShouldAddModelErrorIfNoDeskIsAvailable()
   {
     // Arrange
     _deskBookingResult.Code = DeskBookingResultCode.NoDeskAvailable;

     // Act
     _bookDeskModel.OnPost();

     // Assert
     var modelStateEntry =
       Assert.Contains("DeskBookingRequest.Date", _bookDeskModel.ModelState);
     var modelError = Assert.Single(modelStateEntry.Errors);
     Assert.Equal("No desk available for selected date", modelError.ErrorMessage);
   }

   [Fact]
   public void ShouldNotAddModelErrorIfDeskIsAvailable()
   {
     // Arrange
     _deskBookingResult.Code = DeskBookingResultCode.Success;

     // Act
     _bookDeskModel.OnPost();

     // Assert
     Assert.DoesNotContain("DeskBookingRequest.Date", _bookDeskModel.ModelState);
   }

   [Theory]
   [InlineData(typeof(PageResult), false, null)]
   [InlineData(typeof(PageResult), true, DeskBookingResultCode.NoDeskAvailable)]
   [InlineData(typeof(RedirectToPageResult), true, DeskBookingResultCode.Success)]
   public void ShouldReturnExpectedActionResult(Type expectedActionResultType,
     bool isModelValid, DeskBookingResultCode? deskBookingResultCode)
   {
     // Arrange
     if (!isModelValid)
     {
       _bookDeskModel.ModelState.AddModelError("JustAKey", "AnErrorMessage");
     }

     if (deskBookingResultCode.HasValue)
     {
       _deskBookingResult.Code = deskBookingResultCode.Value;
     }

     // Act
     IActionResult actionResult = _bookDeskModel.OnPost();

     // Assert
     Assert.IsType(expectedActionResultType, actionResult);
   }

   [Fact]
   public void ShouldRedirectToBookDeskConfirmationPage()
   {
     // Arrange
     _deskBookingResult.Code = DeskBookingResultCode.Success;
     _deskBookingResult.DeskBookingId = 7;
     _deskBookingResult.FirstName = "Thomas";
     _deskBookingResult.Date = new DateTime(2020, 1, 28);

     // Act
     IActionResult actionResult = _bookDeskModel.OnPost();

     // Assert
     var redirectToPageResult = Assert.IsType<RedirectToPageResult>(actionResult);
     Assert.Equal("BookDeskConfirmation", redirectToPageResult.PageName);

     IDictionary<string, object> routeValues = redirectToPageResult.RouteValues;
     Assert.Equal(3, routeValues.Count);

     var deskBookingId = Assert.Contains("DeskBookingId", routeValues);
     Assert.Equal(_deskBookingResult.DeskBookingId, deskBookingId);

     var firstName = Assert.Contains("FirstName", routeValues);
     Assert.Equal(_deskBookingResult.FirstName, firstName);

     var date = Assert.Contains("Date", routeValues);
     Assert.Equal(_deskBookingResult.Date, date);
   }
 }
}

然而，当我运行测试时，它只构建，但不运行任何测试，因为它似乎没有发现任何测试。
怎么了？
谢谢
