- 4. 4
- 5. 5 1 ONCE UPON A TIME JAVA ENVIRONMENT
- 6. 6 4
- 7. 7 Everything is testable Everything is measurable Everything is integrated No excuses to have poor apps !
- 8. 8 Great !
- 9. 9 And me ?!
- 10. 10 2 WTF ?! ANDROID IS JAVA !
- 11. 11 Almost YES… … a story of Virtual Machine So what … ?
- 12. 12 3
- 13. Oh Yeah !
- 14. 14 (almost) (almost) Everything is testable Everything is measurable BUT Everything is NOT integrated
- 15. 15 Quality Tools for Android http://goo.gl/zGFvda
- 16. 16 3 Quality Tools Android Ant
- 18. 18 4 Quality Tools Android Maven
- 20. 20 The ultimate profile # run junit, robotium, robolectric tests and get code coverage! > mvn clean install –P jacoco!
- 21. 21 Maven Profiles Junit + Robo,um Robolectric UIAutomator Code coverage standard emma cobertura ui automator spoon jacoco x2 Quality checks (Checkstyle + findbugs + PMD + lint) Sonar
- 22. 22 Android Lint Sonar plugin # analyse code (pmd, checkstyle, findbugs, lint) and report in sonar! > mvn sonar:sonar –P jacoco! hOps://github.com/SonarCommunity/sonar-‐android
- 23. 23 Not an archetype (see akquinet : http://goo.gl/O46LIw) Only samples Do not use everything ! Pick up what you need !
- 24. 24 Return of real life experience Maven Jenkins Sonar (PMD, checkstyle, findbugs, lint) Junit (Instrumenta[onTestCase) ~ 100 screens (phone + tablet) ~ 5 developers during only 5 months ~ 60k loc (java), 15k loc (xml) ~ 400 unit tests : not an excep[onal coverage (~ 30%) Built on each commit on Jenkins + Genymo[on 0 lint, pmd, findbugs, checkstyle viola[ons 1 sonar report generated each night with those metrics è An happy customer J
- 25. 25 Lessons learned A laborious development environment : eclipse + maven + m2eclipse + android m2e connector è Many hours lost è Use IntelliJ ! A laborious execu[on environment : emulator è Too slow è Use Genymo[on (or at least a device) ! Not enough tests : è Instrumenta[onTestCase are too heavy/slow for Unit Tes[ng è Use Robolectric and/or think about MV* paOern è Keep Instrumenta[onTestCase for Android specific (Ac[vity, Services, …)
- 26. 26 Lessons learned A robust development environment : eclipse + maven + m2eclipse + android m2e connector è s[ll some problem with eclipse and maven integra[on About tests è Instrumenta[onTestCase are fast enough with GenyMo[on è Robolectric can’t give you enough confidence
- 27. 27 5 Quality Tools Android Gradle
- 28. 28 Before V 0.6 Lint UIAutomator Monkey & Monkey Runner Robolectric PMD, checkstyle, findbugs Emma, Cobertura, Jacoco
- 29. Joke ?!
- 30. 30 V 0.6.+ Lint UIAutomator Monkey & Monkey Runner Robolectric PMD, checkstyle, findbugs Emma, Cobertura, Jacoco
- 31. 31 Quality # # > # > the gradle way run junit, robotium, robolectric tests ! AND Chekstyle + PMD + Findbugs + Classycle! gradle check! report in sonar! gradle sonarRunner!
- 32. 32 6 Conclusion Android is filling the gap
- 33. Gradle Feature Application Variants & Manifest merging Standard tests & Robo,um Code Coverage Robolectric UI automator / Monkey / Monkey Runner PMD / CheckStyle / FindBgugs / Classycle / Lint Sonar & Project Sites 0.6.1 VS Maven Gradle Maven ? 33 3.6.1
- 34. Android offers 34 lots of quality tools lots of testing methods rapid testing Everything gets easier to use Build rock solid apps
- 35. 35 Thank You ! Any Question ? stephanenicolas jeromevdl snicolas @jeromevdl Stéphane Nicolas & Jérôme Van Der Linden +stephane nicolas +jerome van der linden
