有没有一种简单的方法可以创建一个AutoFixture定制来限制枚举值？

public class EnumCustomization<T> : ICustomization where T : Enum
{
    public void Customize(IFixture fixture)
    {
        fixture.Customizations.Add(new FilteringSpecimenBuilder(new EnumRequestSpecification<T>(), new EnumGenerator<T>()));
    }
}

public class EnumRequestSpecification<T> : IRequestSpecification
{
    public bool IsSatisfiedBy(object request)
    {
        var type = request as Type;
        return type != null && type == typeof(T);
    }
}

public class EnumGenerator<T> : ISpecimenBuilder
{
    public object Create(object request, ISpecimenContext context)
    {
        var type = request as Type;
        if (type != null && type == typeof(T))
        {
            var values = Enum.GetValues(typeof(T));
            return values.GetValue(new Random().Next(values.Length));
        }
        return new NoSpecimen();
    }
}

var fixture = new Fixture();
fixture.Customize(new EnumCustomization<MyEnum>());
