我正在编写单元测试。为了测试以下方法，

public async Task<Guid> CreateWebJobStatus(string blobId, Guid loggedInUserId, string loggedInUserEmail) {

    Guid webJobStatusId = Guid.NewGuid();

    WebJobStatus newWebJobStatus = new WebJobStatus
    {
        WorkJobStatusId = webJobStatusId,
        TransactionId = Guid.NewGuid(),
        Status = (int)WebJobStatusEnum.PENDING,
        BlobId = blobId,
        UserId = loggedInUserId,
        UserEmail = loggedInUserEmail,
    };
    await _dbContext.WebJobStatus.AddAsync(newWebJobStatus);
    await _dbContext.SaveChangesAsync();

    return webJobStatusId;
}

我嘲笑dbset和dbcontext

public async void CreateWebJobStatusTest() {
    var dbOption = new DbContextOptions<TimeSeriesDbContext>();
    var mockDbContext = new Mock<TimeSeriesDbContext>(dbOption);
    var mockConfig = new Mock<IConfiguration>();
    var instance = new WebJobStatusRepository(mockConfig.Object, mockDbContext.Object);
    var mockValidWebJobId = "11111111-1111-1111-1111-111111111111";
    var webjobStatusList …

我有下面的代码，我已经阅读了Moq 和 SqlConnection？ 以及如何存根 IDBconnection，但我仍然不知道如何模拟以下 sqlconnection。

public class SqlBulkWriter : ISqlBulkWriter
{
    private readonly string _dbConnectionString;;

    public SqlBulkWriter(string dbConnectionString)
    {
        this._dbConnectionString = dbConnectionString;
    }

    public void EmptyTable(string schema, string tableName)
    {
        using (var connection = new SqlConnection(this._dbConnectionString))
        {
            try
            {
                connection.Open();
                using (var truncate = new SqlCommand($"TRUNCATE TABLE [{schema}].[{tableName}] ", connection))
                {
                    truncate.ExecuteNonQuery();
                }
            }
            catch (Exception ex)
            {
                throw new Exception(ex);
            }
            finally
            {
                connection.Close();
            }
        }
    }
}

我要为EmptyTable做单元测试，我想我应该先模拟sqlconnection？或者如何对 EmptyTempTable 进行单元测试？

谢谢！许多欣赏！
