What is the
meaning of “Mobile
UI Automation”?

3
Traditional QA procedure
… #100 … #1000 … hours and hours of testing … for each release …

4
UI Automation

import com.android.uiautomator.core.*;
import com.android.uiautomator.testrunner.*;
public class MyTestCase extends UiAutomatorTestCase
{
public void testnumberone() throws UiObjectNotFoundException,
android.os.RemoteException
{
getUiDevice().wakeUp();
getUiDevice().pressEnter();
UiObject textfield = new UiObject(new UiSelector().className("android.widget.EditText"));
textfield.clearTextField();
textfield.setText("This is really cool");
UiObject button = new UiObject(new UiSelector().className("android.widget.Button"));
button.click();
UiObject textview = new UiObject(new UiSelector().className("android.widget.TextView").index(1));
assertEquals("Text is incorrect", "This is really cool", textview.getText());
}
}
$ <apache-ant-dir>/bin/ant build
$ <adt-dir>/sdk/platform-tools adb push bin/MyTestProgram.jar /data/local/tmp
$ <adt-dir>/sdk/platform-tools/adb shell uiautomator runtest MyTestProgram.jar
-c MyTestCase
1. Write the test program
2. Run the tests
3. Read the report

With automation, full test of an
app will no longer take hours
but minutes
The tests are easily repeated
for every release

7
Perfect, right?

.. FOR EACH PLATFORM
BUT TEST PROGRAMS NEED TO BE WRITTEN ..

MANY MOBILE PLATFORMS HAVE BUILT-IN CAPABILITIES
FOR USER INTERFACE AUTOMATION
UI Automation
JavaScript
UIAutomator
Java

public class Main : LayerWidget, EventReceiver
{
TextInputWidget input;
LabelWidget label;
public void initialize() {
base.initialize();
var box = BoxWidget.vertical().set_spacing(px("1mm"))
.set_margin(px("1mm"));
box.add(input = TextInputWidget.instance());
input.set_widget_id("input");
box.add(label = LabelWidget.for_string("(enter text)")
.set_font(Font.instance("7mm")));
box.add(ButtonWidget.for_string("Click me").set_event("clickme")
.set_widget_id("clickme"));
add(CanvasWidget.for_color(Color.instance("#AAAAAA")));
add(box);
set_draw_color(Color.instance("black"));
}
public void cleanup() {
base.cleanup();
input = null;
label = null;
}
public void on_event(Object o) {
label.set_text(input.get_text());
}
}

// standard iOS UI Automation framework initialization
var target = UIATarget.localTarget();
var app = target.frontMostApp();
var window = app.mainWindow();
// Set the contents of the text input field
// to string "Something"
window.textFields()["input"].setValue("Something");
// Click the "Click me" button
window.buttons()["clickme"].tap();
UI Automation test script for iOS

import com.android.uiautomator.core.*;
import com.android.uiautomator.testrunner.*;
{
public void testSample() throws
UiObjectNotFoundException,
{
UiObject textfield = new UiObject(new UiSelector()
.description("input"));
textfield.setText("Something");
UiObject button = new UiObject(new UiSelector()
.description("clickme"));
button.click();
}
}
UIAutomator test script for Android

{
{
button.click();
}
}
SAME PROGRAM WRITTEN TWICE ..
.. SEEMS LIKE A WASTE OF EFFORT

BUT TWICE WOULD
NOT BE ENOUGH

class MyTestCase : UIAutomatorTestCase
{
public void execute() {
get_text_field("input").set_text("Something");
get_button("clickme").click();

r_strptr("Something"));
com.eqela.libuiautomator.UIAutomatorTestCase.prototype.get_button.call(this,
eq.api.StringStatic.for_strptr("clickme")).click();
}

public class UIAutomatorTextFieldAndroid : UIAutomatorTextField

public static UIAutomatorTextFieldAndroid for_id(String id) {
return(new UIAutomatorTextFieldAndroid().initialize(id));
}
ptr field;
public UIAutomatorTextFieldAndroid initialize(String id) {

return(this);
}
public void set_text(String text) {
var ff = field;
var tp = text.to_strptr();
embed {{{

ff.setText(tp);
}}}
}
}

public class UIAutomatorTextFieldIOS : UIAutomatorTextField

var tp = text.to_strptr();
embed {{{
ff.setValue(tp);

}
}

{
{
button.click();
}
}
NO WASTED EFFORT. WRITE THE SCRIPT ONLY ONCE
class MyTestCase : UIAutomatorTestCase
{
public void execute() {
get_text_field("input").set_text("Something");
get_button("clickme").click();
}
}
