Testing module for BubbleSort algorithm. Bubble sort returns empty list with input empy lst. Bubble sort cannot be given a string as input. Bubble sort cannot be given set as input. Bubble sort cannot be given set as input. Bubble sort sorts unordered lst, where len(lst) == 2. Bubble sort sorts unordered_lst, where len(lst) == 16. Bubble sort on list with negative numbers. Bubble sort does not change input lst that is already sorted.
