| 57 | * Class for interacting with the device's UI by simulation user actions and |
| 58 | * introspection of the screen content. It relies on the platform accessibility |
| 59 | * APIs to introspect the screen and to perform some actions on the remote view |
| 60 | * tree. It also allows injecting of arbitrary raw input events simulating user |
Svetoslav | bbfa585 | 2013-02-11 19:38:12 -0800 | [diff] [blame] | 61 | * interaction with keyboards and touch devices. One can think of a UiAutomation |
| 62 | * as a special type of {@link android.accessibilityservice.AccessibilityService} |
| 63 | * which does not provide hooks for the service life cycle and exposes other |
| 64 | * APIs that are useful for UI test automation. |
Svetoslav Ganov | 80943d8 | 2013-01-02 10:25:37 -0800 | [diff] [blame] | 65 | * <p> |
| 66 | * The APIs exposed by this class are low-level to maximize flexibility when |
| 67 | * developing UI test automation tools and libraries. Generally, a UiAutomation |
| 68 | * client should be using a higher-level library or implement high-level functions. |
| 69 | * For example, performing a tap on the screen requires construction and injecting |
| 70 | * of a touch down and up events which have to be delivered to the system by a |
| 71 | * call to {@link #injectInputEvent(InputEvent, boolean)}. |
| 72 | * </p> |
| 73 | * <p> |
| 74 | * The APIs exposed by this class operate across applications enabling a client |
| 75 | * to write tests that cover use cases spanning over multiple applications. For |
| 76 | * example, going to the settings application to change a setting and then |
| 77 | * interacting with another application whose behavior depends on that setting. |
