Here another great quote from Mozilla QA Director Matt Evans (from Part II of his uTest interview).
uTest: In many ways, mobile is still playing catch up to the web. Is there one area in particular where you see the most room for improvement? If so, where?
ME: Well, there are some obvious platform deficiencies around inconsistent UI and whether Flash is going to be fully supported across mobile devices or not. But this is a testing blog, so let’s talk about that. As I mention elsewhere in this interview, mobile is just a really tough testing challenge. The big problem is that there is very little support for cross-platform mobile device test automation. I suspect most of mobile device and application testing is done 100% manually. If any environment needed more test automation, it is mobile. At Palm, we rolled our own test harness that ran on the Pre. This became extremely important for endurance testing and finding memory leaks in the Pre applications.
Mobile software companies have an uphill battle since developing automated system tests for every platform is very costly, both in time and resources. However, reliance on mostly manual testing has lots of quality risks. If the quality of mobile devices and software is to rise about what it is now, we need automated test tool support that works well across all device platforms.
