We argue that there is a need for such data sets that are executable and can therefore be used for experiments using static and dynamic analysis. A harness for such a data set should have high coverage in order to facilitate the construction of comprehensive models of program execution. We present XCorpus, a set of 76 executable, real-world Java programs, including a subset of 70 programs from the Qualitas Corpus. XCorpus uses a harness that is a combination of built-in and generated test cases, resulting in a branch coverage that is significantly better than what is available from DaCapo.Jan-24data set, benchmark, Java, empirical study, program analysis, test case generation, test coverage, dynamic program analysisJournal article10.5381/jot.2017.16.4.a1386887Massey_Dark
