1. The document discusses enhancing the testing experience in Pharo by developing DrTests as a new plugin-based testing UI written in Spec. 2. DrTests would provide a uniform API for running tests via plugins and displaying results in an extensible manner. 3. The goal is to create a testing ecosystem in Pharo that is integrated, extensible via plugins, and able to evolve over time.

- 16. Proposal: Dr Tests Power-up testing experience in Pharo by: Developing and promoting DrTests as the new UI for testing ‣ Written in Spec ‣ Extensible via plugins ‣ Provides good model to configure, run and gather results from plugins !16

- 18. Mini Dr Tests Button to re-run according to configuration Go back to normal UI to configure plugins, input, etc. ➡Simplified view to use a plugin once it is configured !18
- 19. Mini Dr Tests Button’s color gives visual feedback about last result of plugin !19
- 20. Dr Tests model Plugin Configuration Plugin Result Plugin Plugin run, provides updates through announcements Created from UI or by scripting Can be queried from UI or by scripting Can specify class to use Can specify class to use !20
- 21. Conclusion !21
- 22. Vision ★Enhanced SUnit ★Uniform API for SUnit clients ★Plugin-based testing UI = Dr Tests ★More tools to handle tests = Dr Tests plugins ➡We want a testing ecosystem able to evolve !22
- 23. What’s next? Dayne is working on Dr Tests and SUnit enhancements Clothilde will work on Smart Tests soon !23
- 24. can test it! !24
