Mobile application testing is a process by which application software developed for hand held mobile devices is tested for its functionality, usability and consistency. Mobile application testing can be automated or manual type of testing. Mobile applications either come pre-installed or can be installed from mobile software distribution platforms. Mobile devices have witnessed a phenomenal growth in the past few years. A study conducted by the Yankee Group predicts the generation of $4.2 billion in revenue by 2013 through 7 billion U.S. smartphone app downloads. ==Key Challenges in Mobile Application Testing== 1. Variety of Mobile Devices- Mobile devices differ in screen sizes, input methods (QWERTY, touch, normal) with different hardware capabilities. 2. Diversity in Mobile Platforms/OS- There are different Mobile Operating Systems in the market. The major ones are Android, IOS, BREW, BREWMP, Symbian, Windows Phone, and BlackBerry (RIM). Each operating system has its own limitations. Testing a single application across multiple devices running on the same platform and every platform poses a unique challenge for testers. 3. Mobile network operators- There are over 400 mobile network operators in the world; out of which some are CDMA, some GSM, whereas others use less common network standards like FOMA, and TD-SCDMA. Each network operator uses a different kind network infrastructure and this limits the flow of information. 4. Scripting- The variety of devices makes executing the test script (Scripting) a key challenge. As devices differ in keystrokes, input methods, menu structure and display properties single script does not function on every device. 5. Choosing how to test- There are two main ways of testing mobile applications: testing on real devices or testing on emulators. Unfortunately, neither method is flawless. Emulators often miss issues that can only be caught by testing on real devices, but real devices can be expensive to purchase and time-consuming to use for testing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mobile application testing」の詳細全文を読む スポンサード リンク
