I. Introduction
The key objective in the past four editions of the Java Unit Testing Tool Competition emerges from the need to advance research in the automated testing field. We have evidence from the results of the past edition [1]: each single automated testing tool performed worse than human written test cases. Using benchmarking [2] provides a means to mature the state of development of testing tools. Additionally, a benchmark can report useful data to interested parties, e.g. the software industry.
