Android testing samples
===================================
A collection of samples demonstrating different frameworks and techniques for automated testing.
### Espresso Samples
**[BasicSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/BasicSample)** - Basic Espresso sample
**[CustomMatcherSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/CustomMatcherSample)** - Shows how to extend Espresso to match the *hint* property of an EditText
**[DataAdapterSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/DataAdapterSample)** - Showcases the `onData()` entry point for Espresso, for lists and AdapterViews

**[IdlingResourceSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/IdlingResourceSample)** - Synchronization with background jobs
**[IntentsBasicSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/IntentsBasicSample)** - Basic usage of `intended()` and `intending()`
**[IntentsAdvancedSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/IntentsAdvancedSample)** - Simulates a user fetching a bitmap using the camera
**[MultiWindowSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/MultiWindowSample)** - Shows how to point Espresso to different windows
**[RecyclerViewSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/RecyclerViewSample)** - RecyclerView actions for Espresso
**[ScreenshotSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/ScreenshotSample)** - Screenshot capturing and saving using Espresso and androidx.test.core APIs
**[WebBasicSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/WebBasicSample)** - Use Espresso-web to interact with WebViews
**[BasicSampleBundled](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/BasicSampleBundled)** - Basic sample for Eclipse and other IDEs
**[MultiProcessSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/MultiProcessSample)** - Showcases how to use multiprocess Espresso.
### UiAutomator Sample
**[BasicSample](https://github.com/googlesamples/android-testing/tree/main/ui/uiautomator/BasicSample)** - Basic UI Automator sample
### AndroidJUnitRunner Sample
**[AndroidJunitRunnerSample](https://github.com/googlesamples/android-testing/tree/main/runner/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](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/BasicSample)** - Simple usage of `ActivityTestRule`
**[IntentsBasicSample](https://github.com/googlesamples/android-testing/blob/main/ui/espresso/IntentsBasicSample)** - Simple usage of `IntentsTestRule`
**[ServiceTestRuleSample](https://github.com/googlesamples/android-testing/tree/main/integration/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](https://developer.android.com/training/testing) for more information.
Experimental Bazel Support
--------------------------
[](https://buildkite.com/bazel/android-testing)
Some of these samples can be tested with [Bazel](https://bazel.build) 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](https://docs.bazel.build/versions/master/install-ubuntu.html).
### 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](https://docs.bazel.build/versions/master/android-instrumentation-test.html). You may also want to check out [Building an Android App with Bazel](https://docs.bazel.build/versions/master/tutorial/android-app.html), and the list of [Android Rules](https://docs.bazel.build/versions/master/be/android.html) 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](https://github.com/bazelbuild/bazel) repository instead of this repository.
