Prioritizing Program Elements: A Pretesting Effort to Improve Software Quality

Table 9

Mutation score by two testing methods.

Test	TC#	Mu#	EMu#	MS𝑇	MS𝑃
LMS	112	22	2	0.89	0.82
TAS	73	17	0	0.74	0.77
ATM	211	31	7	0.8	0.89

TC#: number of test cases, Mu#: number of mutants, EMu#: number of equivalent mutants, MS_𝑇: mutation score by first testing method (components are prioritized based on complexity), and MS_𝑃: mutation score by second testing method (components are prioritized based on our proposed approach).
