你将如何测试这个场景？
我刚刚开始研究 NHibernate 并在 TDD 上进行了我的第一次 bash。到目前为止，我真的很喜欢它，并且一直在使用 fluent-Nhibernate 来映射类。
但是，在 PersistenceSpecification 上使用 VerifyTheMappings 方法时，我似乎陷入了死胡同。
基本上我有两个类，Recipient 和 RecipientList。RecipientList 类具有到具有流畅“HasMany”关系的收件人的映射：
public class RecipientListMap : ClassMap<RecipientList>
{
public RecipientListMap()
{
Id(x => x.ID);
Map(x => x.ApplicationID);
Map(x => x.Name);
Map(x => x.IsDeleted);
HasMany<Recipient>(x => x.Recipients).WithKeyColumn("RecipientListID").AsList().LazyLoad();
}
}
但是，当我在测试中使用以下代码时：
private IList<Recipient> _recipients = new List<Recipient>()
{
new Recipient { FirstName = "Joe", LastName = "Bloggs", Email = "joe@bloggs.com", IsDeleted = false },
new Recipient { FirstName = "John", LastName = "Doe", Email = "john@doe.com", IsDeleted = false },
new Recipient { FirstName = "Jane", LastName = "Smith", Email = "john@smith.com", IsDeleted = false }
};
[Test]
public void Can_Add_RecipientList_To_Database()
{
new PersistenceSpecification<RecipientList>(Session)
.CheckProperty(x => x.Name, "My List")
.CheckProperty(x => x.Columns, "My columns")
.CheckProperty(x => x.IsDeleted, false)
.CheckProperty(x => x.ApplicationID, Guid.NewGuid())
.CheckProperty(x => x.Recipients, _recipients)
.VerifyTheMappings();
}
出现以下错误：
failed: System.ApplicationException : Expected 'System.Collections.Generic.List`1[Project.Data.Domains.Recipients.Recipient]' but got 'NHibernate.Collection.Generic.PersistentGenericBag`1[Project.Data.Domains.Recipients.Recipient]' for Property 'Recipients'
我可以看到错误是因为我传入了一个列表，而返回的列表是一个 PersistentGenericBag，因此引发了错误。我不明白你是怎么想的，但如果你不能只传递一个 IList？
任何帮助，将不胜感激。
