This short paper reports our observations after six editions of the JUnitContest that benchmarks automated unit test generation tools for Java programs. We discuss our experience and depict the current state-of-the-art and identify potential future research directions. We advocate the use of benchmark as a standard practice to enhance maturity and foster adoption by the industry of automated test case generation tools.@en

We report on the results of the seventh edition of the JUnit tool competition. This year, four tools were executed on a benchmark with (i) new classes, selected from real-world software projects, and (ii) challenging classes from the previous edition. We use Randoop and manual test suites from the projects as baselines. Given the interesting findings of last year, we analyzed the effectiveness of the combined test suites generated by all competing tools and compared; results are confronted with the manual test suites of the projects, as well as those generated by the competing tools. This paper describes our methodology and the results, highlight challenges faced during the contest.@en

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.

After four successful JUnit tool competitions, we report on the achievements of a new Java Unit Testing Tool Competition. This 5th contest introduces statistical analyses in the benchmark infrastructure and has been validated with significance against the results of the previous 4th edition. Overall, the competition evaluates four automated JUnit testing tools taking as baseline human written test cases from real projects. The paper details the modifications performed to the methodology and provides full results of the competition.
