NSubstitute Mocking Expressions along with params

I have a following class called TestClass and has one function.

In TestClass

 public virtual async Task<IEnumerable<T>> GetAll(Expression<Func<T, bool>> predicate, params Expression<Func<T, object>>[] includes)

This is How I am trying to mock the method above using NSubstitute.

  _testClass.GetAll(Arg.Any<Expression<Func<Animal, bool>>>()).Returns(new List<Animal>(){new Animal(), new Animal()});

it complies fine but the mocked method when called does not include the two Animal object in the collection because collection length is zero. I have a feeling since I am not mocking the params part as well thats why this issue is happening. Any one know how to properly mock it?

Cracked it.

Following is how you should do it.

  test.GetAll(Arg.Any<Expression<Func<Animal, bool>>>(),Arg.Any<Expression<Func<Animal,object>>>())
            .Returns(new List<Animal>(){new Animal(), new Animal()});
