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.

Flags for advanced resize tests #

• resize_up_and_resize_down: Trigger a resize up and then a resize down in the same test.
