You can use an android emulator to help you develop your GDSL tests. It is usefull if you do not have a real device or if you want to test on a device with the same resolution as a device on the Test Bench. Do not use emulator if you want measures, the metrics (energy, data …) are not available.

2. Use an android emulator without Greenspector tools

...

• Check the configuration and click on “Finish”. Be careful, the configuration might be different than the one you chose. Make sure to click on “Show Advanced Settings” and check each property.

• Your device is now created. You can launch it by clicking on the triangle.

2.2. Emulators tested

...

• Open the configuration file of your emulator. Replace [device_id] by the id of your device.

  • On Linux and macOS: $HOME/.android/avd/[device_id]/config.ini

  • On Windows: C:\Users\[username]\.android\avd\[device_id]\config.ini

• Sign in with your account

• Click on your profile at the top right of the emulator screen

• Click on Settings > About > Update Play Store

• Wait for the update to complete. It takes several minutes.

• If you want to test a website, search for the Google Chrome app and update it

...

# For newer version of Android SDK
export PATH=$HOME/Android/Sdk/emulator:$PATH

# For older version of Android SDK
export PATH=$HOME/Android/Sdk/tools:$PATH

• On macOS: Update ~/.bashrc or ~/.bash_profile

export PATH=$HOME/Library/Android/Sdk/emulator:$PATH

...

job:
   url: com.google.android.youtubechrome

In the second case, it installs the app at the beginning of the test and uninstalls it at the end.

...

• Launch an android emulator

  • Option 1: open the Device Manager window of Android Studio and click on the triangle

  • Option 2: start an emulator from the command line (part 2.5)

• If you run the testrunner for the first time, you have to run it once without the --no-update option:

  • On Linux and macOS: ./testrunner -jobFile job.yml -config config.yml

  • On Windows: testrunner -jobFile job.yml -config config.yml

• Download the android-service executable in 32 bits and its version file : https://dl.greenspector.com/emulator/android-service-files.tar.gz

• Go to your greenspector cache:

  • On Linux and macOS: $HOME/.greenspector

  • On Windows: C:\Users\[username]\.greenspector

• Replace the android-service and android-service.version files with the downloaded files. You will have to decompress the tar.gz file.

• You can now run the testrunner with the --no-update option:

  • On Linux and macOS: ./testrunner -jobFile job.yml -config config.yml --no-update

  • On Windows: testrunner -jobFile job.yml -config config.yml --no-update
