This is correct, but it is not the best way to cover the original method. The best way is to use the equals() method of the collection itself. This is because the equals() method of the collection is more efficient than the equals() method of the elements of the collection. For example, if we want to cover the method contains() of the class HashSet, we need to modify the generated test as follows:38public void testContainsOnNonEmptyStringCollection() throws Throwable {
