Intermittent issues are not only a maintenance pain, but they also lead to low confidence in the test tools themselves. This presentation goes through a few of the more common reasons for these failures, shares some mitigation strategies and tells some stories about some intermittent failures that were caused by some surprising issues.
With the increased importance of targeting mobile devices in the software development world, we need better tools to assess the quality of the user experience (UX) on these devices. This article introduces the context that creates the need for a model-based approach to evaluate mobile user experience so that different software, or versions of the same software, can be evaluated in a consistent way.
