Flags for add tests #

• “add_first_from_empty”: Check that addFirst works on an empty deque.
• “add_last_from_empty”: Check that addLast works on an empty deque.
• “add_first_nonempty”: Check that addFirst works on a non-empty deque.
• “add_last_nonempty”: Check that addLast works on a non-empty deque.
• “add_first_trigger_resize”: Check that addFirst works when called on a full underlying array
• “add_last_trigger_resize”: Check that addLast works when called on a full underlying array

Flags for add after remove tests #

• “add_first_after_remove_to_empty”: Add some elements to a deque and remove them all, then check that addFirst still works.
• “add_last_after_remove_to_empty”: Add some elements to a deque and remove them all, then check that addLast still works.

Flags for remove Tests #

• “remove_first”: Check that removeFirst works.
• “remove_last”: Check that removeLast works.
• “remove_first_to_empty”: Add some elements to a deque and remove almost all of them. Check that removing the last element with removeFirst works.
• “remove_last_to_empty”: Add some elements to a deque and remove almost all of them. Check that removing the last element with removeLast works.
• “remove_first_to_one”: Add some elements to a deque and remove almost all of them. Check that removing the second to last element with removeFirst works.
• “remove_last_to_one”: Add some elements to a deque and remove almost all of them. Check that removing the second to last element with removeLast works.
• “remove_first_trigger_resize”: Called when usage factor is <= 25% and array size > 8. Checks that the array resizes appropriately.
• “remove_last_trigger_resize”: Called when usage factor is <= 25% and array size > 8. Checks that the array resizes appropriately.

Flags for get Tests #

• “get_valid”: Check that get works on a valid index.
• “get_oob_large”: Check that get works on a large, out of bounds index.
• “get_oob_neg”: Check that get works on a negative index.

Flags for size tests #

• “size”: Check that size works.
• “size_after_remove_to_empty”: Add some elements to a deque and remove them all, then check that size still works.
• “size_after_remove_from_empty”: Remove from an empty deque, then check that size still works.

Flags for isEmpty Tests #

• Is_empty_true Check that size works on an empty deque.
• is_empty_false Check that size works on a non- empty deque.

Flags for toList tests #

• “to_list_empty”: Check that toList works with empty ArrayDeque.
• “to_list_nonempty”: Check that toList works with non-empty ArrayDeque.
