使用 AutoFixture 测试数据生成：解析 ICollection不提每一个T

我尝试使用 AutoFixture 2 为具有 ICollection 成员的 EntityFramework4 类生成测试数据。

    public class Parent
    {
        public virtual ICollection<Child1> Children1 { get; set; }
        public virtual ICollection<Child2> Children2 { get; set; }
        ...
        public virtual ICollection<Child759> Children759 { get; set; }
    }

    var factory = new Ploeh.AutoFixture.Fixture();
    var parent = factory.CreateAnonymous<Parent>();

由于 AutoFixture 无法解析 ICollection 我得到一个 Ploeh.AutoFixture.ObjectCreationException

到目前为止我找到的唯一解决方案是像这样注册每个可能的“ICollection”

    var factory = new Fixture();

    factory.Register<ICollection<Child1>>(() =>
        new List<Child1>());
    ...
    factory.Register<ICollection<Child759>>(() =>
        new List<Child759>());

    var parent = factory.CreateAnonymous<Parent>();

我的问题是

如果需要 ICollection，有人知道一种方法或约定来告诉 AutoFixture 始终使用 List 吗？

原文

I try to use AutoFixture 2 to generate testdata for EntityFramework4 classes that have ICollection member.

    public class Parent
    {
        public virtual ICollection<Child1> Children1 { get; set; }
        public virtual ICollection<Child2> Children2 { get; set; }
        ...
        public virtual ICollection<Child759> Children759 { get; set; }
    }

    var factory = new Ploeh.AutoFixture.Fixture();
    var parent = factory.CreateAnonymous<Parent>();

Since AutoFixture cannot resolve ICollection<Child1> i get an Ploeh.AutoFixture.ObjectCreationException

The only solution i found so far is to register every possible 'ICollection` like this

    var factory = new Fixture();

    factory.Register<ICollection<Child1>>(() =>
        new List<Child1>());
    ...
    factory.Register<ICollection<Child759>>(() =>
        new List<Child759>());

    var parent = factory.CreateAnonymous<Parent>();

My question is

Does anybody know a way or a Convention to tell AutoFixture always to use List<T> if a ICollection<T> is required?
