Mobile application testing verifies the functionality, usability, and consistency of apps designed for handheld devices, facing challenges like device variety, platform diversity, and differing network operators. Key testing methods include functional, performance, and usability testing, and tools like Appium and Calabash support automation. Ensuring effective testing requires local servers for enhanced efficiency and specific tools tailored for different operating systems.

2. 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.

3. Key Challenges in Mobile Application Testing

4. Main Challenges for Mobile app 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.

5. 3. Mobile network operators- There are over 400 mobile
network operators in the world;[4] 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.

21. Why You Need a Local Testing Server (and How To Do It)
 Apache, MySQL and FTP. Since all your files will be hosted on your
computer, you don't need the FTP, but go ahead and start both the Apache
server and the MySQL server.

22. Some Mobile Application Testing Tools
 Cross-Platform (Android and iOS)
 1. Appium - Mobile device automation for functional testing
 2. Calabash - Mobile device automation for functional testing
 3. Perfecto Mobile - Mobile device automation for functional testing
 For Android
 1. Android Lint - This is integrated with Eclipse IDE for Android. This will point out potential bugs,
performance problems
 2. Find Bugs - This is an open source library for static analysis in Java code
 For iPhone
 1. Clang Static Analyzer - An open source tool for running static analysis for iPhone code
 2. Analyze code from XCode - done during compile time

23. Appium –Mobile device automation for
functional testing
 You can use the Selenium WebDriver API for writing tests
which talk to Appium via JSON wire protocol for running the
Selenium commands.
