如何MOQ存储库并确保使用VerifyAll（）调用该方法？

Question

这是存储库类

using System;
using System.Collections.Generic;
using Dealer.Rails.Common.Utils;
using Dealer.Rails.Repository.Entities.C3;
using Dealer.Rails.Repository.Repositories.C3.Interfaces;
using Dealer.Rails.Repository.Repositories.Soar;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;

namespace Dealer.Rails.Repository.Repositories.C3
{
    public class VehicleStagingRepository : BaseRepository, IVehicleStagingRepository
    {

        public VehicleStagingRepository(ILogger<VehicleStagingRepository> logger)
          : base(logger)
        {

        }

        public void SaveVehicleStaging(List<ImportStageVh> vehicleStagingRecords, C3Context c3Context)
        {
            using (var transaction = c3Context.Database.BeginTransaction())
            {
                var vehicleStagingRecordBeforeSaving = new ImportStageVh();

                try
                {
                    foreach (var vehicleStagingRecord in vehicleStagingRecords)
                    {
                        vehicleStagingRecordBeforeSaving = vehicleStagingRecord;
                        c3Context.ImportStageVh.Add(vehicleStagingRecord);
                        c3Context.SaveChanges();
                    }
                }
                catch (TimeoutException tex)
                {
                    transaction.Rollback();
                    _logger.LogError(LoggingEvents.SaveEmployeeStaging, tex.Message);
                    throw;
                }
                catch (Exception ex)
                {
                    transaction.Rollback();
                    _logger.LogError(LoggingEvents.SaveEmployeeStaging, ex, JsonConvert.SerializeObject(vehicleStagingRecordBeforeSaving));
                    throw new Exception(vehicleStagingRecordBeforeSaving.ToString(),ex);
                }

                transaction.Commit();
            }
        }


  }
}

这是使用MOQ的Xunit测试用例。

using Dealer.Rails.Repository.Entities.C3;
using Dealer.Rails.Repository.Repositories.C3;
using Dealer.Rails.Repository.Repositories.C3.Interfaces;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Logging;
using Moq;
using System.Collections.Generic;
using Xunit;

namespace Dealer.Rails.Repository.Tests.Repositories.Rails
{

    public class VehicleStagingRepositoryTests
    {

        [Fact]
        [Trait("Repositories", "C3")]
        public void Should_Dump_Records_To_Vehicle_Staging_Dump()
        {
            // Arrange
            var optionsBuilder = new DbContextOptionsBuilder<C3Context>();
            optionsBuilder.UseSqlServer("Data Source=dev.c3.dealertrack.corp;Initial Catalog=c3_bmc;Integrated Security=True;MultipleActiveResultSets=True;Application Name=EntityFramework");

            var mockLogger = new Mock<ILogger<VehicleStagingRepository>>();

            var mockC3Context = new C3Context(optionsBuilder.Options);
           // var vehicleStagingRecords = new List<ImportStageVh>();

            var mockRepository = new Mock<IVehicleStagingRepository>();
            mockRepository.Setup(x => x.SaveVehicleStaging(It.IsAny<List<ImportStageVh>>(), mockC3Context));

            // System under test is TemplateColumnRepository
            var sut = new VehicleStagingRepository(mockLogger.Object);

            // Act
            sut.SaveVehicleStaging(new List<ImportStageVh>(), mockC3Context);

            // Assert
            mockRepository.Verify();
            // mockRepository.Verify(m=>m.SaveVehicleStaging(vehicleStagingRecords,mockC3Context),Times.Once,"Failed to call SaveVehicleStaging method");
        }


    }
}

MOQ应该允许我独立测试存储库。我面临的问题是

1. 在行optionsBuilder.UseSqlServer中..如果使用optionsBuilder.UseSqlServer（“一些虚拟连接字符串”）;代码抛出异常。我认为它不应该。

2. 在mockRepository.Verify（）;行中，如果使用mockRepository.VerifyAll（），则行失败

3.即使下一个注释行也会抛出错误。在我看来，它应该至少执行一次SaveStagingVehicle方法。

请指导我解决这些问题。
