Automated testing in Python and beyond
- 1. Automated testing in Python and beyond Brenda Wallace Production Engineer, Weta Digital
- 2. Unit Tests Unit Testing is testing of individual program "units" in relative isolation
- 3. Wah? What they are
- 4. Input -> expected output
- 6. Glorified If/Else statements if (stuff happens as expected): OK! else: Fail.
- 7. Python unit tests class testMyCode(unittest.TestCase): def test_Stuff(self): a = MyDataProcessingThing(5) self.assertEqual(a.blah, 9)
- 8. Python Pass, fail, coverage
- 9. Super Powers Massive refactors, and know they worked
- 10. Wanna try something wickedly clever? Do code change quickly
- 11. instantly see if it works for all 1,000 of your use cases
- 12. Confidence Debugging is fast
- 14. Blame.
- 15. You look GOOD.
- 17. Logging capture
- 18. STDOUT capture
- 21. Where ? Check them into a folder called tests
- 23. The Theme There were shortcomings in the other frame work so instead of helping fixing those, we started a new one.
- 24. Java JUnit What everyone uses JTiger There were shortcomings, so instead of fixing those, we started a new one. TestNG Our new one fixes different short comings Looks like python, but with less words
- 25. But life is too short
- 26. Perl Perl Unit
- 27. +60 more on cpan
- 28. Pod::Coverage
- 29. PHP PhpUnit
- 30. SimpleTest Web
- 31. Erlang EUnit
- 32. Best intro to testing ever.
- 33. Write tests Write tests before you write code
- 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.
- 39. Thank You
