Web29 de set. de 2008 · Traditional mutation testing considers only first order mutants, created by the injection of a single fault. Often these first order mutants denote trivial faults that are easily killed. This paper investigates higher order mutants (HOMs). It introduces the concept of a subsuming HOM; one that is harder to kill than the first order mutants from … Web14 de fev. de 2024 · They believed that the combination of two or more errors to generate mutants can cause limited number of easy to kill mutants. The mutants, which are generated in HOMT, are called Higher Order Mutants (HOMs). In the example given in Table 1, we have the program P, one HOM and two first order mutants FOM1, FOM2 of P. WebFirst, we propose a novel way of finding a complete set of higher-order mutants by using variational execution, a technique that can, in many cases, explore large search spaces completely and often efficiently. Second, we use the identified complete set of higher-order mutants to study their characteristics. list of weather stations in canada
