Non-trivial Java Classes to Study the Performance of Search-based Software Testing Approaches

A key factor of studying Evolutionary Algorithms (EA) on automatic test generation is the selection of classes under test. As many open source classes, for example contained in the SF110 corpus, are trivially simple and would not reveal differences between algorithms, a selection of non-trivial classes has been proposed in the DynaMOSA study. This is a corpus of 117 open-source Java projects and 346 classes, selected from four different benchmarks. The complexity of classes ranges from 14 statements and 2 branches to 16,624 statements and 7,938 branches. The average number of statements is 1,109, and the average number of branches is 259.

Java projects/classes and their dependencies are in the subjects directory and here is the set of non-trivial Java classes organized by project:
