DroidBot UTG



DroidBot is a lightweight test input generator for Android. It can send random or scripted input events to an Android app, achieve higher test coverage more quickly, and generate a UI transition graph (UTG) after testing.

A sample UTG is shown here.

DroidBot has the following advantages as compared with other input generators:

  1. It does not require system modification or app instrumentation;
  2. Events are based on a GUI model (instead of random);
  3. It is programmable (can customize input for certain UI);
  4. It can produce UI structures and method traces for analysis.

  1. Python (both 2 and 3 are supported)
  2. Java
  3. Android SDK
  4. Add platform_tools directory in Android SDK to PATH
  5. (Optional) OpenCV-Python if you want to run DroidBot in cv mode.

How to install

Clone this repo and intall with pip:

git clone
cd droidbot/
pip install -e .

If successfully installed, you should be able to execute droidbot -h.

How to use

  1. Make sure you have:

    • .apk file path of the app you want to analyze.
    • A device or an emulator connected to your host machine via adb.
  2. Start DroidBot:

    droidbot -a <path_to_apk> -o output_dir

    That's it! You will find much useful information, including the UTG, generated in the output dir.

    • If you are using multiple devices, you may need to use -d <device_serial> to specify the target device. The easiest way to determine a device's serial number is calling adb devices.
    • On some devices, you may need to manually turn on accessibility service for DroidBot (required by DroidBot to get current view hierarchy).
    • If you want to test a large scale of apps, you may want to add -keep_env option to avoid re-installing the test environment every time.
    • You can also use a json-format script to customize input for certain states. Here are some script samples. Simply use -script <path_to_script.json> to use DroidBot with a script.
    • If your apps do not support getting views through Accessibility (e.g., most games based on Cocos2d, Unity3d), you may find -cv option helpful.
    • You can use -humanoid option to let DroidBot communicate with Humanoid in order to generate human-like test inputs.
    • You may find other useful features in droidbot -h.


We have conducted several experiments to evaluate DroidBot by testing apps with DroidBot and Monkey. The results can be found at DroidBot Posts. A sample evaluation report can be found here.
