   Unit tests for the miscellaneous sort functions.

  
>>> from copy import deepcopy
>>> from nltk.misc.sort import *

A (very) small list of unsorted integers.

  
>>> test_data = [12, 67, 7, 28, 92, 56, 53, 720, 91, 57, 20, 20]

Test each sorting method - each method returns the number of operations required to sort the data, and sorts in-place (desctructively - hence the need for multiple copies).

  
>>> sorted_data = deepcopy(test_data)
>>> selection(sorted_data)
66
  
>>> sorted_data
[7, 12, 20, 20, 28, 53, 56, 57, 67, 91, 92, 720]
  
>>> sorted_data = deepcopy(test_data)
>>> bubble(sorted_data)
30
  
>>> sorted_data
[7, 12, 20, 20, 28, 53, 56, 57, 67, 91, 92, 720]
  
>>> sorted_data = deepcopy(test_data)
>>> merge(sorted_data)
30
  
>>> sorted_data
[7, 12, 20, 20, 28, 53, 56, 57, 67, 91, 92, 720]
  
>>> sorted_data = deepcopy(test_data)
>>> quick(sorted_data)
13
  
>>> sorted_data
[7, 12, 20, 20, 28, 53, 56, 57, 67, 91, 92, 720]
