Exercise: Testing demo - anagrams

---

• An anagram is a pair of words that are created from exactly the same set of characters, but of different order.
• For example listen and silent
• Or bad credit and debit card
• Given the following module with the is_anagram function write tests for it. (in a file called test_anagram.py)
• Write a failing test as well.
• Try doctest, unittest, and pytest as well.

examples/testing-demo/anagram.py

def is_anagram(a_word, b_word):
    return sorted(a_word) == sorted(b_word)

Sample code to use the Anagram module.

examples/testing-demo/use_anagram.py

from anagram import is_anagram
import sys

if len(sys.argv) != 3:
    exit(f"Usage {sys.argv[0]} WORD WORD")

if is_anagram(sys.argv[1], sys.argv[2]):
    print("Anagram")
else:
    print("NOT")
