Question

我有一个域类：

public class Agencia : IEntity
{
    public virtual int Id { get; set; }

    public virtual string Nome { get; set; }

    public virtual string Identificacao { get; set; }

    public virtual IList<Pessoa> Gerentes { get; protected set; }

    public Agencia()
    {
        Gerentes = new List<Pessoa>();
    }

    public virtual void AddGerente(Pessoa gerente)
    {
        Gerentes.Add(gerente);
    }
    public virtual void AddGerentes(params Pessoa[] gerentes)
    {
        Parallel.ForEach(gerentes, (pessoa) => Gerentes.Add(pessoa));
    }
}

public class Pessoa: IEntity
{
    public virtual int Id { get; set; }

    public virtual string Nome { get; set; }

}

使用此约定（定义为set AsSet）

public class AgenciaConvention : IAutoMappingOverride<Agencia>
{
    public void Override(AutoMapping<Agencia> mapping)
    {
        mapping.HasManyToMany(a => a.Gerentes).Cascade.AllDeleteOrphan().AsSet().Not.Inverse();
    }
}

当我运行此测试时：

[TestMethod]
[Description("Uma agência tem vários gerêntes")]
public void AgenciaTemVariosGerentes()
{
    // Arrange
    var fix = new Fixture();
    var currentUser = GetLoggedUser();

    // Create a List<Pessoa>

    var gerentes = fix.Build<Pessoa>()
                        .With(p => p.Nome)
                        .With(p => p.CPF)
                        .With(p => p.CreateBy, currentUser)
                        .OmitAutoProperties()
                        .CreateMany<Pessoa>(10).ToList();

    // Action

    new PersistenceSpecification<Agencia>(Session)
            .CheckProperty(p => p.Nome, fix.Create<string>().Truncate(80))
            .CheckProperty(p => p.Identificacao, fix.Create<string>().Truncate(10))
            .CheckReference(p => p.Regional,
                fix.Build<Regional>()
                    .With(p => p.Nome)
                    .OmitAutoProperties()
                    .Create()
            , new IDEqualityComparer())
            .CheckList(p => p.Gerentes, gerentes, new IDEqualityComparer())
            .CheckReference(p => p.CreateBy, currentUser, new IDEqualityComparer())
            .VerifyTheMappings(); // Assert
}

如何测试此列表？

集合应该是AsSet，父和子字段必须是PK，FK

感谢。

Answer 1

集合未实现IList<T>。

将您的属性定义为ICollection<T>。

无法将'NHibernate.Collection.Generic.PersistentGenericSet`1强制转换为System.Collections.Generic.IList`1
