Today’s remarkable mix of cloud computing, ever-smarter mobile devices, and prolific application development has changed the way we develop and test applications. Now, deployed applications deliver different content and functionality depending on whether the user is accessing it via a browser, a cell phone, a tablet, etc. Moreover, applications are accessed over a myriad of network configurations, including wireless and mobile networks. These new approaches create a previously unseen set of testing challenges. Every user has a different kind of network constraint (mobile network, Wi-Fi, Ethernet…etc.) that directly impacts the behavior and performance of applications. Emulating these constraints by introducing not only connection speeds, but also parameters such as packet loss and network latency is a crucial part of the load testing process. Bill Nicholson presents an in-depth look at the ramifications of these new technologies and testing constraints for mobile application performance. Discover some of the best approaches testers are taking to ensure high mobile application performance delivery to all end-users, at all times, regardless of device.
