C# 单元测试fluent nhibernate存储库，带有内存中的sql lite-无此类表错误
我正在尝试使用Fluent NHibernate为存储库模式编写单元测试。 我选择使用内存中的sqlite数据库，以避免sql server访问（集成测试可以这样做） 以下是我使用的类：C# 单元测试fluent nhibernate存储库，带有内存中的sql lite-无此类表错误,c#,unit-testing,nhibernate,design-patterns,repository,C#,Unit Testing,Nhibernate,Design Patterns,Repository,我正在尝试使用Fluent NHibernate为存储库模式编写单元测试。 我选择使用内存中的sqlite数据库，以避免sql server访问（集成测试可以这样做） 以下是我使用的类： public enum ExpenseCategory { Eat, Clothes, Car, Leisure, Rent, House, Lecture, Trip, Restaurent } public class Expense

有人能帮我解决这个问题吗？发生的事情是打开一个连接，创建表并丢弃连接，然后打开另一个指向空数据库的连接 使用sqlite inmemory时，连接必须始终相同，因为inmemory数据库随连接而存在和消亡 我想：
public ISessionFactory会话{get；set；}public ISession OpenSession（）return\u sessionfactory.OpenSession（\u connection）其中连接与SchemaExport（）中使用的连接相同。执行
我应该在打开会话时保留“使用语法”，还是只在开始时打开会话？我两次都试过了，但仍然有相同的错误。请问，有人能帮我吗？谢谢
