How to overcome device proliferation problem in mobile testing? A practical test design technique called pairwise testing

In the rapidly evolving mobile ecosystem, the proliferation of devices, operating systems, and configurations poses a significant challenge to software testing. Ensuring application functionality across this diverse landscape requires an efficient and effective testing strategy. Pairwise testing emerges as a promising solution to address the device proliferation problem in mobile testing. By focusing on testing combinations of parameter pairs rather than all possible permutations, pairwise testing significantly reduces the number of test cases while still achieving high defect detection rates. This keynote examines the importance of pairwise testing in mobile application testing, demonstrating how it can optimize testing efforts by systematically covering the most critical interactions among devices, operating systems, and other variables.

Through a combination of theoretical analysis and empirical studies, we illustrate that pairwise testing not only enhances test coverage and efficiency but also minimizes costs and time-to-market. Our findings advocate for the broader adoption of pairwise testing as a practical approach to managing the complexities of mobile device proliferation, ensuring robust application performance across diverse environments.
