我正在尝试使用 Sqllite.InMemory 功能设置数据库单元测试。如果我运行单元测试,一切正常。如果我第二次运行相同的测试,我会得到一个 System.Data.SQLite.SQLiteException: no such table: Person
等待一段时间和/或(?)重新启动 Visual Studio 后,我可以再次运行单元测试。
配置或会话处理有问题吗?
public abstract class InMemoryDatabaseFixture : IDisposable
{
private const string ConnectionString
= "Data Source=:memory:;Version=3;New=True;Pooling=True;Max Pool Size=1;";
private readonly ISessionFactory _sessionFactory;
private readonly ISession _session;
protected InMemoryDatabaseFixture()
{
var config = SQLiteConfiguration.Standard.InMemory().ShowSql().ConnectionString(ConnectionString);
_sessionFactory = Fluently.Configure()
.Database(config)
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<SessionContainer>())
.ExposeConfiguration(cfg => new SchemaUpdate(cfg).Execute(true, true))
.BuildSessionFactory();
_session = _sessionFactory.OpenSession();
SessionContainer = MockRepository.GenerateMock<ISessionContainer>();
SessionContainer.Stub(sc => sc.SessionFactory).Return(_sessionFactory);
SessionContainer.Stub(sc => sc.Session).Return(_session);
}
protected ISessionContainer SessionContainer { get; private set; }
public void Dispose()
{
_sessionFactory.Dispose();
_session.Dispose();
}
}
这里是基类的简单用法:
[TestFixture]
public class FinderFixture : InMemoryDatabaseFixture
{
[Test]
public void Test()
{
var finder = new Finder(SessionContainer);
var result = finder.Find();
Assert.That(result, Is.Not.Null);
}
}
更新:经过一些试验,这里终于是我的工作配置。在构建 SessionFactory 之后导出模式是很神奇的。
Configuration configuration = null;
_sessionFactory = Fluently.Configure()
.Database(SQLiteConfiguration.Standard.InMemory().ShowSql())
.ExposeConfiguration(cfg => configuration = cfg)
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<SessionContainer>())
.BuildSessionFactory();
_session = _sessionFactory.OpenSession();
var export = new SchemaExport(configuration);
export.Execute(true, true, false, _session.Connection, null);
