Table 9: Mutation score by two testing methods.

Test TC# Mu# EMu# 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, : mutation score by first testing method (components are prioritized based on complexity), and : mutation score by second testing method (components are prioritized based on our proposed approach).
