The document outlines Tibor Arpáš's initiative to improve testing efficiency in Python development by addressing long wait times associated with running test suites. It introduces a prototype tool called Testmon that focuses on incremental test running and optimizing the test process, which will be open-sourced and supported by an Indiegogo campaign. The overarching goal is to enhance developer tools and promote open-source software crowdfunding.

1. ● freelancer
● but not quite
● mostly Python since 2008
Tibor Arpáš - about me

2. About you

3. When do we wait long minutes
for the computer and what can
be done about it?

4. Users hate waiting
● 100 milliseconds
● 1 second
● 10 seconds

5. So computing adapts
● big improvement in recent years

7. Costs of running tests
● 6 mintues
● 12 thousand commits
● 600 hours

8. Costs of NOT running the tests
● hate and avoidance of the suite
● => hell

9. Vision
● instant test results
● not feasible yet

10. It’s not an easy problem
● But we’ve got ideas! :)

11. Two main ones are
● “incremental” run
● reshuffle

12. Dependency graph

13. Or this

14. Or this

15. Majority of code changes are local
● waste to run the whole test suite each time

16. Reshuffle
● quickest first
● recently broken first

17. Transforming these ideas into a tool
● it’s called testmon (for Python)
● we have a prototype
● it’s going to be opensource
● we’re running an IndieGoGo campaign
● igg.me/at/testmon

18. We need your help
● talk
● share
● contribute on IndieGoGo igg.me/at/testmon

19. Bigger mission
1. Improve developer tools
2. Help to make open source software
crowdfunding business as usual
