WebHigher-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. … WebFeb 14, 2024 · Higher order mutation testing has been proposed to overcome the limitations of traditional mutation testing (also called first order mutation testing) such as a large number of generated mutants, limited realism, and equivalent mutants.

Mutation testing is based on two hypotheses. The first is the competent programmer hypothesis. This hypothesis states that competent programmers write programs that are close to being correct. "Close" is intended to be based on behavior, not syntax. The second hypothesis is called the coupling effect. The coupling effect asserts that simple faults can cascade or couple to form other emergent faults.
WebOct 12, 2015 · These higher order mutant combinations have not been described before. We crossed together the three single mutants to create three double mutants cesa8 irx1–7 cesa7 irx3–6, cesa8 irx1–7 cesa4 irx5–4 and cesa7 irx3–6 cesa4 irx5–4 and the triple mutant cesa8 irx1–7 cesa7 irx3–6 cesa4 irx5–4. Webone, a mutant called a first order mutant is produced. By making several syntactic changes i.e., applying the opera-tors multiple times, a higher order mutant is produced. In this paper we consider only first order mutants. These are generated by applying the operators at all possible locations of the program under test, as supported by the 3 ...

WebJan 4, 2024 · To test their implication and avoid redundancy problems, we analyzed a higher order abi1 loss-of-function mutant, the triple abi1-2 hab1-1 pp2ca-1 knock-out line, which combines defects in the two major PP2C A-type subbranches of ABA signaling, the ABI1 and PP2CA branch (Fuchs et al, 2013 ), and exhibits extreme ABA hypersensitivity (Rubio et al, …
WebDec 1, 2010 · Such a mutant is, by definition, a higher order mutant. We provide a more detailed critique of first order mutation testing and a motivation for the move to the higher order paradigm elsewhere (Jia and Harman, 2009b, Harman et al., 2010). Our aim is to explore the relationship between a mutant’s syntax and its semantics.
