What does assert do?
Short answer. It checks a condition and raises an AssertionError if it is False.
Which values should you test?
Normal values and edges like zero.
Remember
| True: program continues |
| False: AssertionError |
| Test edge values like 0 |
Can one line of code catch a bug? Yes, with assert. Assert checks a condition. Both checks are True, so it prints Passed. True means continue. False gives an AssertionError. Test edges like zero.
