Higher order mutation testing is a relatively new area of research. Researchers have claimed that higher order mutants have the potential to increase test effectiveness and reduce test effort. However, these claims have not been evaluated in the context of the aspect-oriented programming paradigm, which introduces new and unique concepts and constructs, and(More)
Subtle Higher Order Mutants (HOMs) are those HOMs that cannot be killed by existing test suites that kill all First Order Mutants (FOMs) for the program under test. Subtle HOMs simulate complex, real faults, whose behavior cannot be simulated using FOMs. However, due to the coupling effect, subtle HOMs are rare in the exponentially large space of candidate(More)
One goal of higher order mutation testing is to produce higher order mutants (HOMs) that represent subtle faults. We define subtle HOMs as those that are not killed by an existing test set that kills all the first order mutants of a given program. The fault detection effectiveness of the test set can be improved by adding test cases that kill subtle HOMs.(More)
The availability of automated tool support is an important consideration for software developers before they can incorporate higher order mutation testing into their software development processes. This paper presents HOMAJ, a higher order mutation testing tool for AspectJ and Java. HOMAJ automates the process of generating and evaluating first order(More)
