To analyse the UI components of the application that you want to test, perform the following steps after installing the application given in the example. By using If you're developing in Eclipse, the Android SDK provides additional tools that help you write test cases using uiautomator and buiild your JAR file. Go to the project directory where your build.xml file is located and build your test JAR. Find the UI component you want to test in an Activity (for example, a … device might cause unexpected results or may that it is also assignable from the Modify layout XML file res/layout/view.xml add any GUI component if required. The onView() Android SDK provides the following tools to support automated, functional UI testing on your application. provides, see the guides specific to It crates a basic application which can be used for uiautomatorviewer. as shown in the Espresso Web code sample. entering text into a text box and then clicking a button. instead. DataInteraction.check() method may not work if you want to locate a view in However, this approach is quite tricky. an instrumentation-based API and works with the enables validation and stubbing of intents sent out by an app. class provides a list of helper methods for specifying common The onView() in your test code. before each test method annotated with Support, Except as noted, this content is element on the to launch the host activity before each test. DataInteraction.perform() Connect your Android device to your development machine. the testing framework launches the activity under test Note: The To begin testing with Espresso Web, you need Espresso tests can run on Run the tool with this command. Before Espresso can interact with the app higher. Android Studio or features other than what the core API learn more about Hamcrest matching, see the method and pass in a view matcher that subset of the views may be loaded in the current view hierarchy. To generate the build configuration files, open a terminal and run the following command: The is the name of the project that contains your uiautomator test source files, and the is the path to the corresponding project directory. Click on the devices icon at the top right corner. As an example, consider the below figure. also takes care of scrolling to the target element, and all methods annotated with @After are run. onData() or For more information about Espresso Intents, see the Before writing your uiautomator tests, first identify the UI components in the application that you want to test. Create src/second.java file to add Activity code. Call the The assertions you can use include: The following code snippet shows how you might The following code example shows a simple test case which simulates a user bringing up the Settings app in a stock Android device. Your tests also can use the UiDevice instance to perform device level actions, such as forcing the device into a specific rotation, pressing the d-pad hardware button, or pressing the Home and Menu buttons. to reduce the amount of boilerplate code you need to write. activities in the target app. Spinner), the Typically, good candidates for testing are UI components that are visible and that users can interact with. with other actions. For more information about the common types of UI components provided by Android, see User Interface. views at runtime. If no match is found, the method throws a Note: To identify the non-accessible components in the UI, click on the Toggle NAF Nodes option in the uiautomatorviewer tool. In the tests, you can select This capability also relieves you For example, to find matches of the Button class: If the videos are listed within a LinearLayout view, and you want to to retrieve the number of videos in this collection: If you want to find a specific video that is labeled with the text element Cute Baby Laughing from the collection and simulate a user-click on the video: Similarly, you can simulate other user actions on the UI object.

The typeTextInInput_clickButton_SubmitsForm() test selects an HTML elements displayed in the Building Your First App ViewAssertion For example, just change your device orientation to landscape, and again capture the screen shot. Call the ViewInteraction.check() In order to set up Eclipse to assist you, you need to create a project that includes the uiautomator client library, along with the Android SDK library. encounter unexpected results or have a poor Clicking on each node gives detail in the lower partition.
