Build your APK beyond Docker Misumi_Rize / Docker࣮ફLT (Oct. 14,

not Android APK developer
Software Engineer in Test
Testing strategy 1. Unit tests 2. Instrumentation tests 3. Acceptance
tests 4. Exploratory tests
Testing tools 1. JUnit, Mockito 2. Espresso 3. UIAutomator, Appium
4. Human power
Testing APK is difficult → Developer specific problem → CI
service specific problem → APK's state (SQLite, Preference, etc.)
Container CI
Container as CI Service → Docker as a function (Travis
CI, CircleCI, Wercker) → Based on Docker (Drone)
Docker is protocol
https://hub.docker.com/r/misumirize/android-sdk https://github.com/MisumiRize/dockerfiles/tree/ master/android-sdk
FROM misumirize/android-sdk RUN mkdir /project COPY . /project WORKDIR /project
RUN echo "sdk.dir=$ANDROID_HOME" > local.properties ENTRYPOINT ["./gradlew"] CMD ["tasks"]
Run unit tests and generate APK $ docker build -t
android-build . $ docker run android-build build
How can we automate Activity tests?
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
Can we connect to another host (e.g. which real device
is connected) from container?
Problem: → ./gradlew connectedCheck wraps ADB client → We can't
configure the host of ADB client → ADB server binds to the loopback address only
Solution: HAProxy
None
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
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
Separating role is important
https://hub.docker.com/r/misumirize/android- remote-client https://github.com/MisumiRize/dockerfiles/tree/ master/android-remote-client
FROM misumirize/android-remote-client CMD ["connectedAndroidTest", "--stacktrace"]
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"]
ONBUILD is awesome!
But a little dirty hack is needed... build.gradle com.android.ddmlib.DdmPreferences.setTimeOut(60000)
Example: Connect Docker (CircleCI) and DigitalOcean Droplet (Android Atom emulator
working)
Example https://github.com/MisumiRize/HackerNews- Android https://circleci.com/gh/MisumiRize/HackerNews- Android/22 → circle.yml → Vagrantfile
Conclusion → Docker is protocol → Separating role (even forcefully)
is important → ONBUILD is useful. Consider using ONBUILD
Thank you!
