VITRuM

Software testing is the first weapon against software faults, used by developers to preventively locate implementation errors in the exercised production code that may cause critical failures to the inner-working of software systems. According to recent findings, the effectiveness of testing might be not only due to its ability to cover the production code but also to some other properties, like code quality. Among other aspects, the literature reported that an advanced visualization of test-related metrics, e.g., test code coverage on production code, result to be a key strength for developers when dealing with software faults. In this paper, we propose VITRuM (VIsualization of Test-Related Metrics), an IntelliJ plug-in able to provide developers with an advanced visual interface of both static and dynamic test-related metrics that has the potential of making them more able to diagnose production code faults. The plug-in is available in the official JetBrains Plugins Repository. A video showing the tool in action is available at https://youtu.be/kFE81eYPgUg.
