Use Combinatorial Testing for Mobile Device Fragmentation

A common problem in mobile systems testing is the number of hardware, operational, and software configurations that need to be tested. For example, the so-called Android fragmentation problem might lead a test team to test hundreds of device and software configurations, yielding thousands or even tens-of-thousands of tests. A branch of mathematics, called combinatorics, and associated tools exist that allow teams to minimize the number of test cases required, while assuring high error finding percentages. Jon Hagar defines the fragmentation problem and then examines test patterns supported by tools that can help improve testing success. Jon outlines how combinatorial test patterns can be applied to other testing situations. To solve real-world fragmentation problems, he identifies specific tools, which you can take back to your project for quick use. Reference work and data are provided to help your team justify adding combinatorial testing to your mobile test activities.
