8. Example project https://github.com/voghDev/ChuckNorrisJokes #MADGtestsWithK
9. Overview - Basis of the workshop • Custom approach to TDD • Testable code • Android architecture, MVP + Passive View • Kotlin coroutines #MADGtestsWithK
10. http://chucknorris.io API #MADGtestsWithK
11. http://chucknorris.io API #MADGtestsWithK
12. API requests to http://chucknorris.io • Get random joke #MADGtestsWithK
13. API requests to http://chucknorris.io • Get random joke • Get joke by category #MADGtestsWithK
14. API requests to http://chucknorris.io • Get random joke • Get joke by category • Get categories #MADGtestsWithK
15. API requests to http://chucknorris.io • Get random joke • Get joke by category • Get categories • Search jokes by keyword #MADGtestsWithK
16. Example Request: Random joke by category { "category": [ "dev" ], "icon_url": "https://assets.chucknorris.host/img/avatar/chuck-norris.png", "id": "4rfk-ymnth28ny8q2pbrow", "url": "http://api.chucknorris.io/jokes/4rfk-ymnth28ny8q2pbrow", "value": "Chuck Norris went out of an infinite loop." } JSON #MADGtestsWithK

24. Conclusions • TDD is not the real challenge; having testable code is • Tests need to be maintained, as requirements do • The real win is to reproduce bugs directly in your tests • Less executions more productivity #MADGtestsWithK
25. That’s all folks! #MADGtestsWithK
