Basics of Software Testing Knowledge of Software Testing basics is essential in any

kind of testing you perform

Knowing the Telecom basics will always give you anadded advantage

2G, 3G, CDMA, GPRS, GSM, HSCSD, SIM, SMS, WAPare some basic things of telecom that you should beaware of.

Awareness about Mobile OS/Platforms-, iOS( iPhone),Blackberry OS(RIM), J2ME, Symbian, Palm, Windowsphone, Samsung Bada , Nokia Meego and so on

Get familiar with your own Mobile Phone

Mobile Application vs DesktopApplication

Feature On Mobile On Desktop

Screen Resolution

Limited Support for HigherResolution. Site should beoptimized for medium andLow resolution

Supports HigherResolutions

Design Language WML HTML

User InteractionControls

Should be bigger as to beusable from Mobile

Can be of usual size

User InterfaceCan not have lot of frames,2 may be more

Can have as manyframes as needed

Simulator vs EmulatorEmualtor Simulator

Imitation of an object as anotherobject

Imitation of another environment

Emulation is the process of

mimicking the outwardly observablebehavior to match an existing target.

Involves modeling the underlying state ofthe target.

For example:a PlayStation emulator makesPlayStation game CDs recognize a

PC as the machine where they areintended to run. Another example, aman puts on fake breasts, wearwoman clothing and soften his voiceto emulate a woman.

For example:a flight simulator imitates the

environment of flying an airplane in a

little room. The true environment of flyingis experienced in another environmentthat lacks some aspects like thepossibility to die from a plane crash.

15/26



Mobile Handset Testing SMS, MMS, Voice Call, MMS, Phonebook,

Calculator, Bluetooth and other mobile features. Italso includes Multimedia (Camera, Video, Mediaplayer, ringtones) and Mobile Protocol stack testing.

No Downloads required

No installation/uninstallations required

Automatic upgrades handled automatically

A mobile QA here may need to test nativeapplications or features that are available in thephone.

Mobile Application Testing

Applications which are downloadable from differentmobile application stores(Apple App store, AndroidMarket, Getjar, Nokia Ovi Store, Blackberry App worldetc.)

Apart from conventional Functional and UI testing, youmay need to test your application against the submissioncriteria and guidelines provided by these Applicationstores.

Testers role here should not be only functional testing ofmobile app, but also to make sure your applicationadheres to the guidelines provided by these mobile appstores.

Mobile Website Testing(WAP Sites)

Mobile Browser based applications

Accessible through specific URL in the mobile browsers

No installations/un-installations involved

No upgrades involved Definitely need network connectivity

No local storage

Example ValueLabs Mobile Site and other

Testing of Mobile WAP sites has its own challenges.Proper navigation, good user interfaces (design),security, performance and mobile browser compatibilityare important areas

Types of Mobile Apps Testing

User Interface Testing (Color scheme, Menu styles,Consistency of UI over various Devices)

Functional Testing (Testing core functionality of MobileApp as per specification)

Performance & Stress Testing [Behavior of MobileApplication in Low resources(Memory/Space), Behaviorof mobile website when many mobile usersimultaneously access mobile website)]

Usability Testing (Testing of usability aspects of MobileApps)

Apart from above mentioned testing types, some keytesting types may include the following

Testing for Compatibility

Certification Compliance Testing Submission Guidelines Compliance Testing

Interruption Testing (Voice Calls, SMS, Charger, Lowmemory Notification) while application is running.

Monkey Testing Low Network/No Network case Testing

Monitoring Battery Consumption patterns

Observe battery consumption rate as the application is being run inbackground/foreground

Run the application for a long time

Monitoring Memory Usage patters

Observe memory usage pattern as the application is being

Launched

Run In Background

In Foreground

Run the application for Long Time

Check memory usage patterns when in device apart from the pre-installedapplications

No other applications are installed

Most of the free memory is available in the device

Some third party applications are installed

Limited free memory available in Device

Lot of third party applications are installed

Very less free memory available in device

Installation Process on MACTo install the build into a simulator or in the device you needXCODE

XCODE: It is a suite of tools, developed by Apple, fordeveloping software for Mac OS X and iOS

XCODE helps us to invoke simulator in MAC machine

To deploy a new build in Simulator ,Below are the steps

1. Unzip the file sent by client2. Once the file is unzipped a junk folder will be created3. Copy the folder and place it in the simulator location

The following slide demonstrates the point#3 above
