The simplest way to run all SettingsUnitTests is with atest
$ atest SettingsUnitTests
A single class can also be tested with the following command
$ atest -c <YourClassName>
// The following instrutions show how to run the test suite using make + adb //
To build the tests you can use the following command at the root of your android source tree
$ make -j SettingsUnitTests
The test apk then needs to be installed onto your test device. The apk's location will vary
depending on your device model and architecture. At the end of the make command's output, there
should be a line similar to the following:
"Copy: ${ANDROID_PRODUCT_OUT}/testcases/SettingsUnitTests/arm64/SettingsUnitTests.apk"
Install via the following command:
$ adb install -r ${ANDROID_PRODUCT_OUT}/testcases/SettingsUnitTests/arm64/SettingsUnitTests.apk
To run all tests:
$ adb shell am instrument -w com.android.settings.tests.unit/androidx.test.runner.AndroidJUnitRunner
To run all tests in a specific class:
$ adb shell am instrument -w -e class com.android.settings.<class> com.android.settings.tests.unit/androidx.test.runner.AndroidJUnitRunner
To run a specific test:
$ adb shell am instrument -w -e class com.android.settings.<class>#<test> com.android.settings.tests.unit/androidx.test.runner.AndroidJUnitRunner
