WHY — Testing instead of guessing?

Why interviewers care about Testing:

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

3
Django's TestCase builds on
this module.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
