Types of Mobile App Domain Projects: Mobile Application Testing Mobile Handset Testing Mobile Web Site Testing (WAP)

Mobile Application Testing: Mobile Application Testing: – Some applications come pre-installed in mobile handset while some mobile applications are downloadable from different mobile application stores(Apple App store, Android Market, Getjar, Nokia Ovi Store, Blackberry App world etc.). Apart from conventional Functional and UI testing, you may need to test your application against the submission criteria and guidelines provided by these Application stores. As said earlier, tester’s role here should not be only functional testing of mobile app, but also to make sure your application adheres to the guidelines provided by these mobile app stores.

Mobile Application Testing: These applications Can be upgraded with New Features and Bug Fixes Downloadable through AppStore (OVI Store, iTunes, Android Marjet, Getjar etc) OTA (Over the Air) USB Cables Blue Tooth Infra Red Are Platform specific applications Java, Symbian, Black Berry, iOS, Android, Windows Mobile, Palm

Mobile Handset Testing Similar to Organizations that develop third party downloadable mobile applications, there are many companies that develop complete mobile handset. A mobile QA here may need to test native applications or features that are available in the phone. SMS, MMS, Voice Call, MMS, Phonebook, Calculator, Bluetooth and other mobile features. It also includes Multimedia (Camera, Video, Media player, ringtones) features/ Functionalities These applications Shipped/ Embedded along with the mobile devices No Downloads required No installation/unintsllations required Automatic upgrades handled automatically

Mobile Website Testing – WAP Testing Unlike downloadable mobile applications, mobile websites can be accessed via browser. Testing of Mobile WAP sites has its own challenges. Proper navigation, good user interfaces (design), security, performance and mobile browser compatibility are important areas. These applications Are 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 any other WAP Site

Few Popular applications Mobile Applications: Angry Birds Fruit Slice Skype Mobile Handset Application: Smart Guard Photo Funia Image Hider Mobile Website Testing Facebook Any web site

Fundamentals of Mobile Testing Knowledge of Software Testing basics is essential in any kind of testing you perform Knowing the Telecom basics will always give you an added advantage 2G, 3G, CDMA, GPRS, GSM, HSCSD, SIM, SMS, WAP are some basic things of telecom that you should be aware of. Awareness about Mobile OS/Platforms-, iOS( iPhone), Blackberry OS(RIM), J2ME, Symbian, Palm, Windows phone, Samsung Bada , Nokia Meego and so on Get familiar with your own Mobile Phone

Mobile Platforms An operating system manages the hardware and software resources of smart phones. Some OS platforms cover the entire range of the software stack. Others may only include the lower and rely on additional software platforms to provide a user interface framework. Some Most Popular Types of Mobile OS iPhone OS Android Symbian Java Black Berry Bada Windows Mobile Palm

iPhone iOS Platform Pocket size version of the Mac OS X, was shrunk and redesigned to power the Apple Device (iPad, iPhone, iPOD) Apple doesn’t permit the use of its OS on third-party hardware. A smart user interface, thousands of apps, millions of downloads from app store and a revolutionizing user-experience. iPhone OS has four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device’s storage. Presently XCode3.1 is the development environment and the applications are written in Objective C (a variant of language C). Application Size can be unlimited Great User Interface Purchased/ Free applications are available in Appstore Various number of applications available in Appstore

Android Backed by Google, presently owned by Open Handset Alliance, Android is more than just an operating system. It is a software stack encompassing middleware and key applications and is based on a modified version of Linux Kernel. The Android SDK includes debugger, libraries, a handset emulator, documentation, sample code, and tutorials. Google promotes application development for Android based phones by having a dedicated team at their own end and also organizing developer competitions from time to time. Google’s own participation in app development for Android platform – These applications include Google Voice, Sky Map, Finance, Maps Editor, Places Directory for their Local Search, Google Goggles that searches by image, Google Translate, Listen for podcasts and My Tracks. Ginger Bread Supports Android versions 2.3, 2.3.2, 2.3.3, 2.3.4 Honey Comb Supports Android versions 3.0, 3.1, 3.2 Numerous Applications are available in Android Market File contains with .apk extension files

Black Berry Proprietary software platform, created by Research In Motion (RIM), for BlackBerry phones. The operating system provides multitasking and supports specialized input devices that have been adopted by RIM for use in its handhelds, particularly the track wheel, trackball, and most recently, the trackpad and touch screen The BlackBerry platform is perhaps best known for its native support for corporate email, through MIDP 2.0, which and allows complete wireless activation and synchronisation with Microsoft Exchange File contains “.alx” and “.cod” files. Can be installed through JAD and JAR files

Other OS Platforms Windows Mobile Microsoft Windows API Visual C++, .net Compact Framework Current Version “Windows Mobile 6.5” BADA Developed By Samsung Electronics Developed in C++, BADA SDK Java Palm OS Doja

Platform extensions JAVA JAD and JAR Black Berry: JAD & COD JAD & JAR ALX & COD Android APK Mac OS ipa Windows Exe Samsung Bada Symbian sys
