Answer 1

This is weird. "remove" doesn't remove an element in a specific position, like "erase" do. It will instead remove all elements with the same value. Your objects (Test) doesn't hold any value, nor does it have a equality operator that can be used to check for equality.
Try adding an attribute to Test and implement the equality operator.
