Feature phone

• Contains a fixed set of functions beyond voice calling and text messaging

• Not as extensive as a smartphone.

• For example, – offer Web browsing and e-mail, but

generally cannot download apps from an online marketplace, such as Whatsapp

Smartphone

• With built-in applications and Internet access.

• Advanced application programming interfaces (APIs)

• Able to run different kinds of free and paid third-party applications to have better integration with the phone's OS and hardware

Moblie Apps Development platforms


• Development Kit for some of the popular platforms:

Overview of Development Platforms for Mobile App Development

iOS Android BlackBerry Windows

Mobile/Windows Phone

Symbian

iOS SDK Android SDK BlackBerry Java Development Environment (JDE)

Windows Mobile – Microsoft Visual Studio 2008

Windows Phone – Windows Phone Developer Tools

Qt SDK, Symbian^3 SDK

Page 20


• Other than SDK, each mobile platform has additional development tools for facilitating the programming.

• Developing multiple mobile apps with single source code

• Some tools use web standards for development while some need to use proprietary programming languages.

• For development tools using web standards, they work in two approaches. – generate the codes as embedded web content

within the mobile app (e.g. PhoneGap)– recompile the web codes into native codes (e.g.

Titanium Mobile)

Cross-Platform Development Tools

Page 24


These tools have some common limitations:

• Most of the tools cannot support all common mobile OS platforms.

• Although web standards are used by some of these tools, some advanced features like AJAX are not supported by tools like MotherApp.

• Performance of mobile apps developed by these tools may not as good as those developed by native programming language.

• Most of the tools do not provide API for interfacing with Bluetooth and video capture.

MOBILE APPS TESTING

Mobile Application Testing

Mobile Testing

Mobile App Diversity

• Integration with existing Systems

• Accelerated Development

• Performance & Security

• Backward Compatibility

Challenges


• Quick swipe (user experience, quit app scenarios)

• Orientation

• Different devices (resolutions, compatibility)

• No network scenario

• Features Test (esp. cross app cases)

• Stress Test (including server side)

Testing Strategy for Mobile App

Components of Mobile Testing


• Mobile emulator provides an easy way for testing the application without the needs of actual device.

• Emulator cannot perform some hardware related testing– onboard camera– GPS,– sensors,– multitouch,– telephony,– accelerometer feedback

• Testing with actual device must be conducted before the application is released.

Tool Selection Criteria

Some Popular Mobile Testing Tools

Mobile Automation – Desktop Based

• Mobile test automation tools are installed on a desktop locally

• Interacts with the mobile devices Through USB connection or Wi-Fi

• Mobile Apps can be installed & tested on both Emulators and real devices

Mobile Automation - Image vs Object Recognition

Comparison of Mobile Test Tools in Market

• Stable Automation Framework useful across multiple Platforms

• Use Emulators for Automation early in the development cycle

• Use Real device for automation only to emulate real time usage

When to plan Automation?

1. Define the automation scope

2. Select the Test Automation Tool suitable for your application and supports multiple Oss

3. Start by building automation scripts for smoke testing

4. Gradually build a basic test suite for regression testing that represents business critical use cases

How to implement Automation Tools?

• Supports Android applications for Auotmation

• Robotium RC can be utilized to run testscripts in a Test Lab setup

Robotium

Mobile Infrastructure - Emulators

Mobile Infrastructure – Real Devices

• Test Early and Often

• Create matrix of Platforms, Device, Network Connections (2G, 3G, wi-fi, LTE, etc.), Carriers for Testing (Including different OS versions)

• Test for Performance and Security

• Keep Target Audience in mind while testing

• Tool selection should take into account emulator and real device support across platforms

Best Practices

PRACTICAL CASE SHARINGSick Bird Free

SOS! Sick Bird病咗鳥

SOS! Sick Bird 病咗鳥• Search location & provide information of HK government clinics

• Search the nearest government clinic

• Provide telephone number and address of the clinic

• Provide map view to identify the locations

• Augmented reality (AR) function

• Service target: Hong Kong residents / visitors

Introduction

• Multi-language:Traditional Chinese,Simplified Chinese, andEnglish

• Positioning function(GPS):Identify the current location

• Facebook Login:Sign in Facebook accounts to facilitate sharing of content

Setting

Map View (with GPS function)

• Clinics under the Hospital Authority

• Clinics / Health Centres under the Department of Health

Clinic location

• Find the location of the clinic based on the actual circumstances by the AR function

Augmented reality (AR) function

• Top right radar displays the position and the number of clinics within a specified range

• Range of the radar can be adjusted by the bottom bar, increasing or decreasing the number of clinics

Augmented reality (AR) function

• Different clinic information can be shared with friends and relatives via Facebook
