I have spent a couple days testing out the new UiAutomator API and
thinking that it is like a bridge between android instrumentation and
monkeyrunner. By using this APIs, you can develop test case with minimum knowledge
and less effort. You don’t need to do any pre-setup like package boundaries and
configuring manifest file permissions.
While designing a test case using Robotium, You must need to include some
critical steps like extending from ActivityInstrumentationTestCase2 and passing
in the name of the target class creating the constructor that takes no
arguments.
But here you don’t need to do anything. You can just create a normal Java
project with default folder structure and build the test.jar file with project dependency UIAutomater.jar file
Here as the sample UIAutomater Sample Test case.
public void testDemo() throws UiObjectNotFoundException {
// Press home button.... Don’t care about where your device status or previous
test case where you opened.
getUiDevice().pressHome();
// open the All Apps view
UiObject allAppsButton = new
UiObject(LauncherHelper.ALL_APPS_BUTTON);
allAppsButton.click();
// clicking the APPS tab
UiSelector appsTabSelector =
new
UiSelector().className(android.widget.TabWidget.class.getName())
.childSelector(new UiSelector().text("Apps"));
UiObject appsTab = new
UiObject(appsTabSelector);
appsTab.click();
// Clicking the Settings
UiScrollable allAppsScreen = new
UiScrollable(LauncherHelper.LAUNCHER_CONTAINER);
allAppsScreen.setAsHorizontalList();
UiObject clockApp =
allAppsScreen.getChildByText(LauncherHelper.LAUNCHER_ITEM, "Clock");
clockApp.click();
// Set an alarm to go off in about 2 minutes
setAlarm(2);
// wait for the alarm alert dialog
UiObject alarmAlert =
new UiObject(new
UiSelector().packageName("com.google.android.deskclock")
.className(TextView.class.getName()).text("Alarm"));
assertTrue("Timeout while waiting for
alarm to go off",
alarmAlert.waitForExists(2 * 60 * 1000));
clickByText("Dismiss");
}
private void setAlarm(int minutesFromNow) throws
UiObjectNotFoundException {
UiObject setAlarm = new UiObject(new
UiSelector().textStartsWith("Alarm set"));
if (!setAlarm.exists())
setAlarm = new UiObject(new
UiSelector().textStartsWith("Set alarm"));
setAlarm.click();
clickByDescription("Add alarm");
clickByText("Time");
UiSelector minuteAreaSelector = new
UiSelector().className(
android.widget.NumberPicker.class.getName()).instance(1);
UiSelector minuteIncreaseButtonSelector =
minuteAreaSelector.childSelector(
new UiSelector().className(android.widget.Button.class.getName()).instance(1));
for (int x = 0; x < minutesFromNow; x++)
new
UiObject(minuteIncreaseButtonSelector).click();
clickByText("Done");
UiObject doneButton = new UiObject(new
UiSelector().text("Done"));
UiObject okButton = new UiObject(new
UiSelector().text("OK"));
if (doneButton.exists()) {
doneButton.click();
} else {
okButton.click(); // let it
fail if neither exists
}
clickByText("Done");
getUiDevice().pressHome();
}
private void clickByDescription(String text) throws UiObjectNotFoundException
{
UiObject obj = new UiObject(new
UiSelector().description(text));
obj.clickAndWaitForNewWindow();
}
private void clickByText(String text) throws UiObjectNotFoundException {
UiObject obj = new UiObject(new
UiSelector().text(text));
obj.clickAndWaitForNewWindow();
}
