  1. 1. The Monkey Tool Goofing around with Android
  2. 2. A UI/Application Exerciser ● The Monkey is a command-line tool that that you can run on any Android emulator instance or on a device. ● It sends a pseudo-random stream of user events into the system, which acts as a stress test on the application software you are developing.
  3. 3. History and Availability ● The Monkey is a built-in Android UI testing tool, and can be accessed through use of the adb (android debugging bridge) supplied to android developers for free by Google.
  4. 4. Other UI/App Testing Tools ● There aren’t any other popular Android UI automated testing tools -- the Monkey tool is meant to be used as a stress-test, while other tools use specific test cases. ● Although ‘monkeyrunner’ is similar to the monkey tool in some ways, Google states that they are unrelated.
  5. 5. Sustainability and Performance ● Since the Monkey is included as part of the Android SDK, it is kept up-to-date by Google and has excellent reliability. ● However, testing on an external device, rather than a virtual one, leads to much faster results and less headache. Running the tool on a virtual device can take a lot of processing power.
  6. 6. Benefit / Cost ● The tool is packaged with the Android SDK, so it is free to use. This also means that it is compatible with any existing Android project. ● In order to use the monkey, just navigate to the android-sdk folder in your shell, and run the monkey tool on any connected device. Anyone with the sdk can do this.
  7. 7. Running the Tool ● The monkey has no GUI interface ● So it must be run from a shell.
  8. 8. Running the Tool ● In order to run the monkey, you must have an android device (virtual or otherwise) connected to adb. ● You can only have one device running at a time.
  9. 9. Running the Tool ● After starting up, the monkey begins sending user interface events to the device; this is viewable in real time.
  10. 10. Running the Tool ● Since the tool is random (pseudo-random), and you can control the amount of tests, the app can end up in odd situations.
  11. 11. Testing On Your Own ● In order to use the monkey tool, navigate to your android-sdk folder, and from there to platform-tools. ● From here, you can run the adb tool. ADB comes with a ‘shell’ option, which allows you to access the android device directly.
  12. 12. Testing On Your Own ● However, you can simply execute the tool through the adb shell, without actually going through the device files. ○ The ‘-p’ option allows you to choose a specific package for the tool to browse. ○ The ‘-v’ option is for setting something called ‘verbosity’ every -v added increases level of detail ○ The number (1000) at the end of the command is
  13. 13. Thoughts ● The Monkey tool is fairly simple to use, and is a great for apps that have a significant amount of user input involved. ● For many apps, which only receive user input for buttons, or small text boxes, then the uses for this tool are limited. ● But if your app requires constant input (like drawing apps), or simultaneous inputs (like a game), then it could be very beneficial.
