/**
* A utility similar to {@link IteratorTester} for testing a
* {@link ListIterator} against a known good reference implementation. As with
* {@code IteratorTester}, a concrete subclass must provide target iterators on
* demand. It also requires three additional constructor parameters:
* {@code elementsToInsert}, the elements to be passed to {@code set()} and
* {@code add()} calls; {@code features}, the features supported by the
* iterator; and {@code expectedElements}, the elements the iterator should
* return in order.
*
* The items in {@code elementsToInsert} will be repeated if {@code steps} is
* larger than the number of provided elements.
