We report on the organization, challenges, and results of the tenth edition of the Java Unit Testing Competition as well as the second edition of the Cyber-Physical Systems (CPS) Testing Competition.

Java Unit Testing Competition. Seven tools, i.e., BBC, EvoSuite, Kex, Kex-Reflection, Randoop, UTBot, and UTBot-Mocks, were executed on a benchmark with 65 classes sampled from four open-source Java projects, for two time budgets: 30 and 120 seconds.

CPS Testing Tool Competition. Six tools, i.e., AdaFrenetic, AmbieGen, FreneticV, GenRL, EvoMBT and WOGAN competed on testing two driving agents by generating simulation-based tests. We considered one configuration for each test subject and evaluated the tools' effectiveness and efficiency as well as the failure diversity.

This paper describes our methodology, the statistical analysis of the results together with the competing tools, and the challenges faced …
