onData()entry point for Espresso, for lists and AdapterViews

BasicSample - Basic UI Automator sample
AndroidJunitRunnerSample - Showcases test annotations, parameterized tests and testsuite creation
**All previous samples use ActivityTestRule or IntentsTestRule but there's one specific to ServiceTestRule:
BasicSample - Simple usage of
IntentsBasicSample - Simple usage of
ServiceTestRuleSample - Simple usage of
These samples use the Gradle build system. To build a project, enter the project directory and use the
./gradlew assemblecommand or use "Import Project" in Android Studio.
./gradlew connectedAndroidTestto run the tests on a connected emulator or device.
./gradlew testto run the unit test on your local host.
There is a top-level
build.gradlefile if you want to build and test all samples from the root directory. This is mostly helpful to build on a CI (Continuous Integration) server.
Many of these samples use the AndroidX Test Library. Visit the Testing site on developer.android.com for more information.
Some of these samples can be tested with Bazel on Linux. These samples contain a
BUILD.bazelfile, which is similar to a
build.gradlefile. The external dependencies are defined in the top level
This is experimental feature. To run the tests, please install the latest version of Bazel (0.12.0 or later) by following the instructions on the Bazel website.
# Clone the repository if you haven't. $ git clone https://github.com/google/android-testing $ cd android-testing
Edit the path to your local SDK at the top of the WORKSPACE file
$ $EDITOR WORKSPACE
Test everything in a headless mode (no graphical display)
$ bazel test //... --config=headless
Test a single test, e.g. ui/espresso/BasicSample/BUILD.bazel
$ bazel test //ui/uiautomator/BasicSample:BasicSampleInstrumentationTest_21_x86 --config=headless
Query for all android_instrumentation_test targets
$ bazel query 'kind(android_instrumentation_test, //...)' //ui/uiautomator/BasicSample:BasicSampleInstrumentationTest_23_x86 //ui/uiautomator/BasicSample:BasicSampleInstrumentationTest_22_x86 //ui/uiautomator/BasicSample:BasicSampleInstrumentationTest_21_x86 //ui/uiautomator/BasicSample:BasicSampleInstrumentationTest_19_x86 //ui/espresso/RecyclerViewSample:RecyclerViewSampleInstrumentationTest_23_x86 //ui/espresso/RecyclerViewSample:RecyclerViewSampleInstrumentationTest_22_x86 //ui/espresso/RecyclerViewSample:RecyclerViewSampleInstrumentationTest_21_x86 //ui/espresso/RecyclerViewSample:RecyclerViewSampleInstrumentationTest_19_x86 //ui/espresso/MultiWindowSample:MultiWindowSampleInstrumentationTest_23_x86 //ui/espresso/MultiWindowSample:MultiWindowSampleInstrumentationTest_22_x86 ...
Test everything with GUI enabled
$ bazel test //... --config=gui
Test with a local device or emulator. Ensure that
adb deviceslists the device.
$ bazel test //... --config=local_device
If multiple devices are connected, add --device_serial_number=$identifier where $identifier is the name of the device in
$ bazel test //... --config=local_device --test_arg=--device_serial_number=$identifier
For more information, check out the documentation for Android Instrumentation Tests in Bazel. You may also want to check out Building an Android App with Bazel, and the list of Android Rules in the Bazel Build Encyclopedia.
android_instrumentation_test.target_deviceattribute still needs to be specified even if
adb shell pm list packages com.example.android.testing | cut -d ':' -f 2 | tr -d '\r' | xargs -L1 -t adb uninstall
