Investigating coverage-reliability relationship and sensitivity of reliability to errors in the operational profile

The focus of the work is an investigation into the correlation between “true” reliability of a software system and the white box testing measures such as block coverage, c-uses and p-uses coverage. We believe that software reliability and testing measures, especially white box testing, are inherently related. Results from experiments are presented to support this belief. We also demonstrate that the estimated reliability is sensitive to the operational profile defined for the software and hence errors in the operational profile may lead to incorrect reliability estimates
