3. Stéphane Nicolas BoundBox   And  others  :  RoboDemo,  Quality  Analysis  Tools  for  Android,  android-­‐maven-­‐plugin,  …   3   +stephane  nicolas   snicolas   stephanenicolas  
5. JAVA ENVIRONMENT ONCE UPON A TIME 1 5  
6. 6   4  
7. Everything is testable Everything is measurable Everything is integrated No excuses to have poor apps ! 7  
8. Great ! 8  
9. And me ?! 9  
10. 2 WTF ?! ANDROID IS JAVA ! 10  
11. Almost YES… … a story of Virtual Machine So what … ? 11  
12. 12   3  
13. Oh Yeah !
14. (almost) Everything is testable (almost) Everything is measurable BUT Everything is NOT integrated 14  
15. Quality Tools for Android http://goo.gl/zGFvda 15  
16. 3 Quality Tools Android Ant 16  
18. 4 Quality Tools Android Maven 18  
19. <plugin>! <groupId>com.jayway.maven.plugins.android.generation2</groupId> "! <artifactId>android-maven-plugin</artifactId>! <version>3.6.1</version>! </plugin>! The magical plugin 19  
20. The ultimate profile # run junit, robotium, robolectric tests and get code coverage! > mvn clean install –P jacoco! 20  
21. Maven Profiles Junit  +   Robo,um Robolectric UIAutomator Code   coverage Quality   checks   (Checkstyle  +   findbugs  +   PMD  +  lint) Sonar standard emma cobertura ui   automator spoon jacoco 21   x2  
22. 22   hOps://github.com/SonarCommunity/sonar-­‐android   # analyse code (pmd, checkstyle, findbugs, lint) and report in sonar! > mvn sonar:sonar –P jacoco! Android Lint Sonar plugin
23. Not an archetype (see akquinet : http://goo.gl/O46LIw) Only samples Do not use everything ! Pick up what you need ! 23  
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   24  
25. 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,  …)     Lessons learned 25  
26. 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       Lessons learned 26  
27. 5 Quality Tools Android Gradle 27  
28. Lint UIAutomator Monkey & Monkey Runner Robolectric PMD, checkstyle, findbugs Emma, Cobertura, Jacoco 28   Before     V  0.6  
29. Joke ?!
30. Lint UIAutomator Monkey & Monkey Runner Robolectric PMD, checkstyle, findbugs Emma, Cobertura, Jacoco 30   V  0.6.+  
31. 31   Quality the gradle way # run junit, robotium, robolectric tests ! # AND Chekstyle + PMD + Findbugs + Classycle! > gradle check! # report in sonar! > gradle sonarRunner!
32. 6 Conclusion Android is filling the gap 32  
33. 33   Feature Gradle Maven Application Variants & Manifest merging ? Standard  tests  &  Robo,um Code  Coverage   Robolectric UI  automator  /  Monkey  /   Monkey  Runner PMD  /  CheckStyle  /   FindBgugs  /  Classycle  /  Lint Sonar  &  Project  Sites Gradle 0.6.1 VS Maven 3.6.1
34. 34   Android offers lots of quality tools lots of testing methods rapid testing Everything gets easier to use Build rock solid apps
