Modern software systems are increasingly configurable. While this has many benefits, it also makes some software engineering tasks,such as software testing, much harder. This is because, in theory,unique errors could be hiding in any configuration, and, therefore,every configuration may need to undergo expensive testing. As this is generally infeasible, developers need cost-effective technique for...
Software configurability has many benefits, but it also makes programs much harder to test, as in the worst case the program must be tested under every possible configuration. One potential remedy to this problem is combinatorial interaction testing (CIT), in which typically the developer selects a strength t and then computes a covering array containing all t-way configuration option combinations...
Many modern software systems are designed to be highly configurable, which increases flexibility but can make programs hard to test, analyze, and understand. We present an initial empirical study of how configuration options affect program behavior. We conjecture that, at certain levels of abstraction, configuration spaces are far smaller than the worst case, in which every configuration is distinct...
