This document discusses continuous integration from unit tests to hardware. It describes how continuous integration helps ensure quality by automatically building and testing software anytime code changes are committed. The speaker's company Forget Box uses Jenkins for continuous integration to build and test their iOS app daily. Plugins and scripts can be used in Jenkins to run unit tests, compute code coverage, package apps, and deploy to test devices. Continuous integration helps developers catch bugs early and "never break the build again."

- 1. CONTINUOUS INTEGRATION FROM UNIT TESTS TO HARDWARE Rémy Virin Cocoaheads @remyvirin
- 2. WHO AM I ? LIMA ? • I’m an iOS software engineer at Forget box. • We’re creating a new way to store your data. • Backed on kickstarter • 12,8K backers • $ 1,2 Millions
- 3. BEFORE, 10 YEARS AGO One User One device One Memory
- 4. TODAY, MULTIPLE DEVICES, MULTIPLE MEMORIES One User Multiple devices Divided memories
- 5. TODAY, CLOUD SOLUTION IS JUST A PATCH One User Multiple devices Divided memories
- 6. TODAY, CLOUD SOLUTION IS JUST A PATCH One User One Unified Memory
- 7. CONTINUOUS INTEGRATION FROM UNIT TESTS TO HARDWARE
- 8. WHY ?
- 10. SHIP, SHIP, SHIIIIP SHIP, SHIP, SHIIIIP !!! !!!
- 11. MEASURE QUALITY • Photo quality
- 12. HOW ?
- 13. C.I. BASICS Execute unit tests Publish app to mktg Continuous Integration Fetch sources Generate Documentatio n Workstations Generate metrics Execute functional tests
- 14. SAS vs LOCAL
- 15. JENKINS
- 16. ABOUT JENKINS • Open Source • Easy to install • Best known CI solution
- 17. INSTALL JENKINS
- 18. ADD PLUGINS
- 19. ADD PLUGINS
- 20. CREATE A JOB CREATE A JOB
- 21. CREATE A JOB • Set up Github url and restrict where the job should be run if your mac is a node of Jenkins.
- 22. CREATE A JOB WITH PLUGINS
- 23. CREATE A JOB WITH A SCRIPT Build your project, run Unit Tests, compute code coverage, package your app, deploy it etc… $ pod install $ xcodebuild -workspace Lima.xcworkspace -scheme "Lima" -destination=build -configuration Debug_deploy -sdk iphoneos7.0 ONLY_ACTIVE_ARCH=YES clean build archive $ xcodebuild -exportArchive -exportFormat "IPA" archivePath "$NEW_ARCHIVE" -exportPath ./Lima.ipa exportProvisioningProfile "Lima Adhoc Distribution" # And then upload to testflight via curl Full script here: https://gist.github.com/rvirin/7796647
- 24. PLUGINS vs SCRIPTS Most of the time, plugins are easier to use. Sometimes we don’t have other choices to use plugins Examples : • cocoapods plugin if podFile is not in root folder • run Unit tests with Xcode plugin
- 25. THAT’S IT, YOU CAN ENJOY NOW…
- 26. AND ONE DAY, THE BUILD FAIL !
- 27. WE NEED TO KNOW WHEN BUILD FAILED • Basic Alert : Email • Growl Notification : Hudson-on-cocoa • Or you can connect Jenkins to your real life…
- 28. YOU’LL NEVER BROKE THE BUILD AGAIN ! Code source : https://github.com/codedance/Retaliation
- 29. BOTS ON iOS
- 30. SETUP - REQUIREMENTS • A mac (at least 10.9) • OS X Server • Xcode
- 31. SETUP • Install OS X Server and Xcode on your mac • Activate Xcode as a service of your server • Connect to remote repository • Create your first bot
- 32. ERRORS DURING SETUP • Error on getting source code -> no error, big logs for nothing • Add _teamserver public key to your Github repository (deploy keys)
- 33. ERRORS DURING SETUP • CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 7.0’ just trying to build the app ! • Get your provisionning profile on the mac server (Add your account to Xcode)
- 34. SETUP • If you have to install your pods before building your app : • $ sudo visudo -f /etc/sudoers • Add this line : # Same thing without a password # %wheel ALL=(ALL) NOPASSWD: ALL %_teamsserver ALL=(ALL) NOPASSWD: ALL
- 35. • v Source : Cocoapods mailing list
- 36. PODS IN XCODE •
- 37. PODS IN XCODE •
- 38. COOL THINGS ON BOTS • Bots Can be created and monitored from Xcode. • Integrate with Xcode • UI and UX rocks.
- 39. BAD THINGS ON BOTS • Lots of bugs • Fetching pods before building app is painfull • No 3rd party integration (Testflight, hockeyapp etc…) • Can’t Archive an app • Need to create a specific scheme
- 40. SONAR An open source platform for Continuous Inspection of code quality
- 41. SONARQUBE •
- 42. SONARQUBE • Issues with OCLint are powerfull • Generate Documentation, Count lines of code, analyze code duplication and run Unit Tests ! • https://github.com/octo-technology/sonarobjective-c
- 43. NEXT STEP : HARDWARE NEXT STEP : HARDWARE
- 44. CONCLUSION
- 45. IMPROVEMENTS • « Thanks to Jenkins I’m able to test the last version of our app just by pressing a button, it’s awesome ! » Alex Product Guy at Lima
- 46. IMPROVEMENTS • « Each day at 4pm, we get a new build of our app, it’s really efficient to reduce the amount of bugs » Tester at Meetic (Dating website)
- 47. COST : 8 to 10 % of the project
- 48. THANKS !
