| /** |
| * 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. |
| * |
| * <p>The items in {@code elementsToInsert} will be repeated if {@code steps} is larger than the |
| * number of provided elements. |
