#UI/Application Exerciser Tests UI/application exerciser tests are stress test using random generated users events. ##Running Locally The Android SDK provides a test tool called [Monkey](http://developer.android.com/tools/help/monkey.html), "a program that runs on your emulator or device and generates pseudo-random streams of user events such as clicks, touches, or gestures, as well as a number of system-level events." To exercise Monkey on the test app, install the package on the device (e.g. via Android Studio) and then: ``` $ adb shell monkey -p com.mapbox.mapboxgl.testapp -v 500 ``` ##Running on AWS Device Farm Amazon Device farm supports a similar tool called `Built-in Fuzz Test`. "The built-in fuzz test randomly sends user interface events to devices and then reports results."
