Moq无法模拟没有特定泛型的方法

Question

I have a test that find all class that inherited from BaseClass . BaseClass has a property with a method that use generics:

abstract class BaseClass 
{
   public MyTools Tools { get; set;}

   public abstract List<TEntity> GetAll();

   public virtual IList<TEntity> Convert<TEntity, TEntityOther>() 
   {
       //...
   }
}

class MyTools 
{
   IList<T> List<T>();    
}

Then, I need to mock the T List<T>() method. The method is used in Create method. For example:

class MyClass: BaseClass<MyEntity>
{
    public override List<MyEntity> GetAll()
    {
        var x = this.MyTools.List<SomeClass>();

        return this.Convert<MyEntity, SomeClass>(x);
    }
}

I don't know what type is used within GetAll to call List method.

This is my test:

var xobjects = this.GetTypeInNamespace(myAssembly, typeof(BaseClass<>));

foreach(var obj in xobjects) 
{
   var myTools  = new Mock<MyTools>();

   //here is my problem
   myTools.Setup(x => x.List< ANY >()).Returns(new List< ANY >());

   var iobj = this.CreateInstance(obj);

   iobj.MyTools = myTools.Object;  

   var result = iobj.GetType().GetMethod("GetAll").Invoke(iobj, null);

   ((ICollection)result).Count.Should().Be(0);
}

How I can setup the method List <T> for any T?

I don't know what type is T and I do not care what type it is.

我知道这个问题It.IsAnyType 3年的历史了，但是由于moq 4.13 ，可以为通用类型匹配指定It.IsAnyType 。
