AndroidJUnitRunner Sample

AndroidJunitRunnerSample - Showcases test annotations, parameterized tests and testsuite creation

JUnit4 Rules Sample

**All previous samples use ActivityTestRule or IntentsTestRule but there's one specific to ServiceTestRule:

BasicSample - Simple usage of

ActivityTestRule

IntentsBasicSample - Simple usage of

IntentsTestRule

ServiceTestRuleSample - Simple usage of

ServiceTestRule

Prerequisites

  • Android SDK v28
  • Android Build Tools v28.03

Getting Started

These samples use the Gradle build system. To build a project, enter the project directory and use the

./gradlew assemble
command or use "Import Project" in Android Studio.
  • Use
    ./gradlew connectedAndroidTest
    to run the tests on a connected emulator or device.
  • Use
    ./gradlew test
    to run the unit test on your local host.

There is a top-level

build.gradle
file 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.

AndroidX Test Library

Many of these samples use the AndroidX Test Library. Visit the Testing site on developer.android.com for more information.

Experimental Bazel Support

Build status

Some of these samples can be tested with Bazel on Linux. These samples contain a

BUILD.bazel
file, which is similar to a
build.gradle
file. The external dependencies are defined in the top level
WORKSPACE
file.

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.

Bazel commands

# 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 devices lists 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 adb devices

$ 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.

Known issues:

  • Building of APKs is supported on Linux, Mac and Windows, but testing is only supported on Linux.
  • android_instrumentation_test.target_device
    attribute still needs to be specified even if
    --config=local_device
    is used.
  • If using a local device or emulator, the APKs are not uninstalled automatically after the test. Use this command to remove the packages:
    • adb shell pm list packages com.example.android.testing | cut -d ':' -f 2 | tr -d '\r' | xargs -L1 -t adb uninstall

Please file Bazel related issues against the Bazel repository instead of this repository.
