Android uiautomater sample test case with assert verification

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();

}
