1. Build your APK beyond Docker Misumi_Rize / Docker࣮ફLT (Oct. 14, 2015)
2. Log.d("introduction", me); → Twitter @Misumi_Rize → GitHub @MisumiRize → I'm not Android APK developer
3. Software Engineer in Test
4. Testing strategy 1. Unit tests 2. Instrumentation tests 3. Acceptance tests 4. Exploratory tests
5. Testing tools 1. JUnit, Mockito 2. Espresso 3. UIAutomator, Appium 4. Human power
6. Testing APK is difficult → Developer specific problem → CI service specific problem → APK's state (SQLite, Preference, etc.)
7. Container CI
8. Container as CI Service → Docker as a function (Travis CI, CircleCI, Wercker) → Based on Docker (Drone)
9. Docker is protocol
10. https://hub.docker.com/r/misumirize/android-sdk https://github.com/MisumiRize/dockerfiles/tree/ master/android-sdk
11. FROM misumirize/android-sdk RUN mkdir /project COPY . /project WORKDIR /project RUN echo "sdk.dir=$ANDROID_HOME" > local.properties ENTRYPOINT ["./gradlew"] CMD ["tasks"]
12. Run unit tests and generate APK $ docker build -t android-build . $ docker run android-build build
13. How can we automate Activity tests?
14. Too slow and frustrating ARM emulator cf. Travis CI $ echo no | android create avd --force \ --name test --target android-23 --abi armeabi-v7a $ emulator64-arm -avd test -no-skin -no-audio -no-window & $ android-wait-for-emulator $ adb shell input keyevent 82 & $ ./gradlew connectedCheck
15. Can we connect to another host (e.g. which real device is connected) from container?
16. Problem: → ./gradlew connectedCheck wraps ADB client → We can't configure the host of ADB client → ADB server binds to the loopback address only
17. Solution: HAProxy
19. Client (container) frontend local_adb_server bind 127.0.0.1:5037 mode tcp default_backend remote_adb_server backend remote_adb_server mode tcp server remote01 123.45.67.89:5036 check
20. Server (devices connected) frontend remote_adb_server bind *:5036 mode tcp default_backend internal_adb_server backend internal_adb_server mode tcp server internal01 127.0.0.1:5037 check
21. Separating role is important
22. https://hub.docker.com/r/misumirize/android- remote-client https://github.com/MisumiRize/dockerfiles/tree/ master/android-remote-client
23. FROM misumirize/android-remote-client CMD ["connectedAndroidTest", "--stacktrace"]
24. misumirize/android-remote-client ONBUILD COPY haproxy.cfg /etc/haproxy/haproxy.cfg ONBUILD COPY . /project WORKDIR /project ONBUILD RUN echo "sdk.dir=$ANDROID_HOME" > local.properties ENTRYPOINT ["execute-remote"]
25. ONBUILD is awesome!
26. But a little dirty hack is needed... build.gradle com.android.ddmlib.DdmPreferences.setTimeOut(60000)
27. Example: Connect Docker (CircleCI) and DigitalOcean Droplet (Android Atom emulator working)
28. Example https://github.com/MisumiRize/HackerNews- Android https://circleci.com/gh/MisumiRize/HackerNews- Android/22 → circle.yml → Vagrantfile
29. Conclusion → Docker is protocol → Separating role (even forcefully) is important → ONBUILD is useful. Consider using ONBUILD
