我有一个使用Entity framework 6.1.3的DB层,并且使用数据库优先方法创建模型,因此有一个*.edmx描述模型的文件.
我创建了一个部分类来公开单元测试使用的额外构造函数,如下所示:
public partial class Entities
{
public Entities(DbConnection connection)
: base(connection, true)
{
}
}

简单的单元测试如下所示:
private Entities CreateContext()

//var connectionString = ConfigurationManager.ConnectionStrings["Entities"].ConnectionString;
//var connection = Effort.EntityConnectionFactory.CreateTransient(connectionString);
//return new Entities(connection as DbConnection);
var connection = Effort.EntityConnectionFactory.CreatePersistent("name=Entities");
var context = new Entities(connection);
return context;

我在Visual Studio和C#中使用Effort来重新创建和单元测试数据库.我正在为一个表编写一个类,所以我只使用该表中的对象填充数据库.我的问题是Effort数据库希望对象的外键引用数据库中的实际对象.
我的错误是
System.Data.Entity.Infrastructure.DbUpdateException:更新条目时发生错误.有关详细信息,请参阅内部异常
System.Data.Entity.Core.UpdateException:更新条目时发生错误.有关详细信息,请参阅内部异常
System.Reflection.TargetInvocationException:调用目标抛出了异常.
NMemory.Exceptions.ForeignKeyViolationException:外键违规[Table1 :: SettingsId].引用的表[Table2 :: SettingsId]中不存在键值[0].错误代码:RelationError
由于此特定表具有许多具有许多其他外键的对象的外键,因此需要大量工作.有没有办法在努力将其关闭以便我可以单独测试这张桌子?
