To build the tests you can use the following command at the root of your android source tree

$ make SettingsTests



The test apk then needs to be installed onto your test device via for example

$ adb install -r out/target/product/shamu/data/app/SettingsTests/SettingsTests.apk



To run all tests:

$ adb shell am instrument -w com.android.settings.tests/android.support.test.runner.AndroidJUnitRunner



To run all tests in a specific class:

$ adb shell am instrument -w -e class com.android.managedprovisioning.<class> com.android.managedprovisioning.tests/android.test.InstrumentationTestRunner



To run a specific test:

$ adb shell am instrument -w -e class com.android.settings.<class> com.android.settings.tests/android.support.test.runner.AndroidJUnitRunner
