Step up handset test with adaptive test case

A critical part of ensuring the successful launch and delivery of new multimedia services is comprehensive testing. Not only are emerging multimedia applications fairly complex compared with more-traditional cellular services, they tend to be data-intensive, performance-sensitive, and require more involved user interactions. As a consequence, developers need to test not only the mechanisms used to transport data, but also the perceived quality of the user experience.

Subscribers expect the flawless delivery of cellular services, which is difficult to guarantee when services can be accessed and used in a myriad of ways. For example, a photo taken on one handset may need to be transcoded in order to be viewed on a handset with a different screen resolution. The cost of failure (i.e. an image is clipped or of poor quality) is high: If subscribers encounter difficulties in using the exciting new features for which they specifically purchased a premium-priced handset, their willingness and enthusiasm to continue to pay for enhanced services will quickly fade, potentially leading to their adopting a new carrier with more consistent and reliable service delivery.

Implementing a comprehensive testing methodology, however, is not a trivial process. Testing of even simple functions requires many distinct test cases when one considers the different ways in which services can be initiated and interact with one another.
