Just-In-Time Bug Prediction in Mobile Applications: The Domain Matters!

Bug prediction allows developers to focus testing efforts on specific areas of software systems. While this topic has been extensively studied for traditional applications, investigations on mobile apps are still missing. In this paper we preliminarily study the effectiveness of a previously defined Just-In-Time bug prediction model applied on five mobile apps. Key results indicate the poor performance of the model and the need of further research on the topic.
