The document discusses automated testing in Python and other languages. It covers unit testing, how unit tests work in Python using the unittest module, the benefits of testing like refactoring with confidence and faster debugging. It also briefly mentions test frameworks for other languages like Java, Perl, PHP and Erlang. The key themes are that testing finds bugs, helps refactor code safely, and that when frameworks have shortcomings the better approach is to help fix them rather than starting new ones.

4. Input -> expected output

5. That's a test

6. Glorified If/Else statements if (stuff happens as expected): OK! else: Fail.

11. instantly see if it works for all 1,000 of your use cases

13. Find bugs elsewhere

14. Blame.

15. You look GOOD.

17. Logging capture

18. STDOUT capture

19. Running single tests

22. Keep in git/whatever

25. But life is too short

27. +60 more on cpan

28. Pod::Coverage

32. Best intro to testing ever.

35. On cron e.g. every hour

36. On commit, poll git for changes

37. Email everyone when it breaks

38. Email only the person who broke it.
