The mobile testing framework approach proposed earlier represents the difference between a suboptimal point solution and a fully integrated optimized solution. By leveraging this framework, product development and validation organizations can:
1) cut overall testing costs by as much as 30 to 50 percent;
2) accelerate product deliveries to market by as much as 20 percent; and,
3) increase the volume of new product release testing by as much as 25 percent.
Following are details about each key element of the framework:
Using this technique, devices are tested within a particular geography while running on a wireless service provider network. But tests are conducted from a remote location by accessing the handset over the Internet and monitoring responses on the tester's computer.
A large part of a handset test specification does not need a live network. Network-independent tests can be manually run on the handset. This type of test can be moved to locations where tester availability and costs are lower. But offshore solutions can also be defined in terms of opening access to field testers within any given geographic area.
Service providers with a global network of talent and testing experience may have the ability to conduct tests in various geographical locations, sparing the manufacturers or carrier the costs of flying experts to the field location and setting up relevant field tests.
Simulated Network Testing
Simulated network testing is used for new feature testing when network infrastructure is not ready for network tests. Using a simulated network, the technique provides a network condition under which a reasonable number of defects can be identified.
When designing a handset testing framework, it's essential to fully leverage automation, which needs upfront investments; automation also needs careful evaluation and selection of the right approach for a given product to ensure optimal investment returns.
Automation also makes it possible to execute a test library, allowing the library to conclude that a defect resolution has taken care of all possible scenarios in which a defect can potentially occur. Such results are impossible to achieve through manual testing.
The different market pressures and dynamics in the wireless industry are intense. This poor testing situation is one of the most serious and potentially opportunistic for those companies who decide they want to do it better, less expensively, and more reliably.
