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.
