Java Unit Testing Tool Competition - Sixth Round

We report on the advances in this sixth edition of the JUnit tool competitions. This year the contest introduces new benchmarks to assess the performance of JUnit testing tools on different types of real-world software projects. Following on the statistical analyses from the past contest work, we have extended it with the combined tools performance aiming to beat the human made tests. Overall, the 6th competition evaluates four automated JUnit testing tools taking as baseline human written test cases for the selected benchmark projects. The paper details the modifications performed to the methodology and provides full results of the competition.
