Critical Review of BugSwarm for Fault Localization and Program Repair
share
Benchmarks play an important role in evaluating the efficiency and effectiveness of solutions to automate several phases of the software development lifecycle. Moreover, if well designed, they also serve us well as an important artifact to compare different approaches amongst themselves. BugSwarm is a benchmark that has been recently published, which contains 3,091 pairs of failing and passing continuous integration builds. According to the authors, the benchmark has been designed with the automatic program repair and fault localization communities in mind. Given that a benchmark targeting these communities ought to have several characteristics (e.g., a buggy statement needs to be present), we have dissected the benchmark to fully understand whether the benchmark suits these communities well. Our critical analysis has found several limitations in the benchmark: only 112/3,091 (3.6 to evaluate techniques for automatic fault localization or program repair.
