PB - ELSEVIER SCIENCE BV ID - discovery10079131 N2 - Failed Error Propagation (FEP) can reduce test effectiveness and recent work proposed an information theoretic measure, Squeeziness, as the theoretical basis for avoiding FEP. This paper demonstrates that Squeeziness is not suitable for comparing programs with different input domains. We then extend Squeeziness to Normalised Squeeziness and demonstrate that this is more generally useful.
