Yota: Yet anOther Testing toolkit for Android

Yota is a toolkit for Android testing. It is equipped with the functionalities like

• querying UI elements;
• dumping the UI hierarchy ;
• inputting an event;
• monky-like random testing;
• etc.

Notice

Yota is developed and tested on deviced with rootable adb (i.e., adb root works).

                             exited by send key BACK, by default, don't stop

Debug

Step1: start the debugger

If you are using Android 8 or below:

$ YOTA_DEBUG_USE_OLD=true YOTA_DEBUG=true ./yota [...]

Otherwise:

$ YOTA_DEBUG=true ./yota [...]

Step2: forward the debugger

Above commands will start a debugger using JDWP on port 5005 on the device, then forward that port to the desktop:

$ adb forward tcp:5005 tcp:5005

Step3: set breakpoints and connect to the debugger

Set your breakpoints in Android Studio.

Then in the menu: Run > Debug > Edit configurations.... Click on + > Remote, and fill the following:

• Host: localhost
• Port: 5005

Then click Debug.
