The
uiautomator
testing framework lets you test your user interface (UI) efficiently by creating automated functional UI testcases that can be run against your app on one or more devices.
For more information on testing with the
uiautomator
framework, see
UI Testing
.
Syntax
To run your testcases on the target device, you can use the
adb shell
command to invoke the
uiautomator
tool. The syntax is:
adb shell uiautomator runtest <JARS> -c <CLASSES> [options]
Here’s an example:
adb shell uiautomator runtest LaunchSettings.jar -c com.uia.example.my.LaunchSettings
Command-line Options
The following table describes the subcommands and options for
uiautomator
.
Subcommand | Option | Description |
---|---|---|
runtest
|
<JARS>
|
Required
. The
<JARS>
argument is the name of one or more JAR files that you deployed to the target device which contain your uiautomator testcases. You can list more than one JAR file by using a space as a separator.
|
-c <CLASSES>
|
Required (API 17 or lower)
.The
<CLASSES>
argument is a list of test classes or test methods in
<JARS>
to run.
Each class or method must be fully qualified with the package name, in one of these formats:
Note:
This argument is not required for API 18
and higher. If not specified, all test cases in
|
|
--nohup
|
Runs the test to completion on the device even if its parent process is terminated (for example, if the device is disconnected). | |
-e <NAME> <VALUE>
|
Specify other name-value pairs to be passed to test classes. May be repeated.
Note:
The
|
|
-e debug [true|false]
|
Wait for debugger to connect before starting. | |
dump [file]
|
Generate an XML file with a dump of the current UI hierarchy. If a filepath is not specified, by default, the generated dump file is stored on the device in this location
/storage/sdcard0/window_dump.xml
.
|
|
-e outputFormat simple | -s
|
Enables less verbose JUnit style output. | |
events
|
Prints out accessibility events to the console until the connection to the device is terminated |
uiautomator API
The
uiautomator
API is bundled in the
uiautomator.jar
file under the
<android-sdk>/platforms/
directory. The API includes these key classes, interfaces, and exceptions that allow you to capture and manipulate UI components on the target app:
Classes
Class | Description |
---|---|
com.android.uiautomator.core.UiCollection
|
Used to enumerate a container's user interface (UI) elements for the purpose of counting, or targeting a sub elements by a child's text or description. |
com.android.uiautomator.core.UiDevice
|
Provides access to state information about the device. You can also use this class to simulate user actions on the device, such as pressing the d-pad hardware button or pressing the Home and Menu buttons. |
com.android.uiautomator.core.UiObject
|
Represents a user interface (UI) element. |
com.android.uiautomator.core.UiScrollable
|
Provides support for searching for items in a scrollable UI container. |
com.android.uiautomator.core.UiSelector
|
Represents a query for one or more target UI elements on a device screen. |
com.android.uiautomator.core.Configurator
|
Allows you to set key parameters for running uiautomator tests. |
Interfaces
Interface | Description |
---|---|
com.android.uiautomator.core.UiWatcher
|
Represents a conditional watcher on the target device. |
com.android.uiautomator.testrunner.IAutomationSupport
|
Provides auxiliary support for running test cases. |
com.android.uiautomator.testrunner.UiAutomatorTestCase
|
Defines an environment for running multiple tests. All
uiautomator
test cases should extend this class.
|
Exceptions
Exception | Description |
---|---|
com.android.uiautomator.core.UiObjectNotFoundException
|
Indicates when a a
UiSelector
could not be matched to any UI element displayed.
