Efficiently Finding Higher-Order Mutants

Web22 de mar. de 2024 · Testing plays a crucial role in software development for ensuring quality. Mutation testing in general and higher order mutation in particular are the good techniques to evaluate the quality of test data, i.e. determining if test data can uncover errors.

Can Higher-Order Mutants Improve the Performance of Mutation …

Web12 de set. de 2024 · Mutation testing is an effective but time consuming method for gauging the quality of a test suite. It functions by repeatedly making changes, called mutants, to the source code and checking whether the test suite fails (i.e., whether the mutant is killed). Recent work has shown cases in which applying multiple changes, called a higher order … 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.

Higher Order Mutation Testing - ScienceDirect

WebHigher-order mutants are enabled by creating mutants with more than one mutation. Mutation testing is done by selecting a set of mutation operators and then applying them to the source program one at a time for each applicable piece of the source code. The result of applying one mutation operator to the program is called a mutant. WebWhile most research on mutation analysis has focused on first-order mutants, recent studies claim that higher-order mu- tants are less likely to be equivalent mutants [36, 49, 52, 61] and that higher-order mutants can reduce test effort [21, 23, 65]. In Section2, we will discuss a specific use case with a motivating example.

WebHigher order mutation testing is an idea presented by Jia and Harman and in a manifesto by Harman et al. . This promising idea offers solutions to overcome the limitations of traditional mutation testing. Mutants can be classified into two types: First Order Mutants (FOMs) and Higher Order Mutants (HOMs). WebExploiting higher-order mutants instead of first-order mutants is one way used in literature to approach this problem [12]. Higher-order mutants can be created by partitioning the set of first-order mutants randomly, and combining first-order mu-tants in each partition into higher-order mutants. The benefits of higher-order mutation are ...
