如何用列表和关系对象测试流畅的NHibernate的PersistenceSpecification.VerifyTheMappings?

您将如何测试这种情况?

我刚刚开始研究NHibernate并在TDD上进行了第一次bash。到目前为止,我真的非常喜欢它,并且一直使用流利的Nhibernate来映射类。

然而,在PersistenceSpecification上使用VerifyTheMappings方法时,我似乎遇到了死胡同。

基本上我有两个类,Recipient和RecipientList。 RecipientList类具有到Recipient的映射,具有流畅的“HasMany”关系:

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();
        }

发生以下错误:

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List并且返回的列表是PersistentGenericBag,因此抛出错误。如果你不能只是传入一个IList,我不知道你怎么测试这个?

任何帮助都将不胜感激。

答案 0 :(得分:9)

愚蠢的是我在PeristenceSpecification上使用了错误的方法。

我应该一直使用CheckList而不是CheckProperty。

咄!
