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. Webfocused on first-order mutants, higher-order mutation is promis-ing: For example, recent studies claim that higher-order mutants are less likely to be equivalent mutants [35, 50, 53, 62], and that higher-order mutants can reduce test effort [21, 23, 68]. In Sec-tion 2, we discuss a specific use case of higher-order mutants with a motivating ...

Web19 de abr. de 2024 · Higher-order mutants (HOMs) are proposed to simulate complex faults and can be applied in MBFL theoretically for multiple-fault localization scenarios (MFL-scenario). However, whether HOMs can improve MBFL’s performance is not investigated and the effectiveness is not thoroughly evaluated. WebAbstract. Since Mutation Testing was proposed in the 1970s, it has been considered as an effective technique of software testing process for evaluating the quality of the test data. In other words, Mutation Testing is used to evaluate the fault detection capability of the test data by inserting errors into the original program to generate ...

WebTo simulate real complex faults, higher-order mutants (HOMs) were presented. A HOM is a mutant that has more than one injected fault. The order of mutants represent the number of injected faults.
