The landscape of mobile devices and operating systems is rapidly evolving. Market fragmentation is a growing problem for mobile application developers. Varying screen sizes, new device types, and updated operating systems are constantly being introduced to the market.
As a result, mobile QA teams must be able to accommodate a wide variety of device and OS combinations in order to ensure consistently high user experiences. Comprehensive manual testing across multiple devices and operating systems can slow production significantly, and can contribute to delayed deployments or missed deadlines.
An emerging alternative to conventional forms of mobile application testing is crowdsourced testing. Crowdsourced testing provides access to a larger tester pool, while still allowing organizations to test their products on real devices. Instead of taking the time to repeat the same tests across all relevant devices and operating systems, QA testers and engineers can leverage crowdsourced testing for repetitive tests.
The expense of buying and maintaining devices and operating systems for testing in-house can also be offset by crowdsourced testing. Crowdsourcing provide your team with access to a more diverse set of devices and browsers, without having to maintain a large set of physical devices in-house, giving your team better test coverage.
Automating as many tests as possible is often seen as the best approach to fast, efficient quality assurance. But automation still requires a significant amount of time and resources to set up and maintain. With deployment cycles moving faster and faster, automation isn't always a viable replacement for manual testing. 53% of IT leaders say that their application functionality changes too frequently to use testing automation effectively.
As testing needs for established devices, operating systems and features stabilize, opting for automation can make large test suites more manageable. By systematically writing and implementing automated tests for established test cases and scenarios, you’ll free up time to spend developing and executing tests for newer devices as they hit the market.
