#[cfg(test)]mod tests {    #[test]    fn it_works() {        assert_eq!(2 + 2, 4);    }}
  1. Before we add further tests, let's add a subject that needs testing. In this case, let's use something interesting: a singly linked list from our other book (Hands-On Data Structures and Algorithms with Rust) made generic. It consists of three parts. First is a node type:
#[derive(Clone)]struct Node<T> where T: Sized + Clone {    value: T,    next: Link<T>,}impl<T> Node<T> ...
