An estimated method for software testability measurement

Abstract

Software testability is becoming an important factor to be considered during software development and assessment, especially for critical software. The paper gives software testability, previously defined by Voas (1991, 1992), a new model and measurement which is done before random black-box testing with respect to a particular input distribution. The authors also compared their measurement results with the one simulated according with Voas's model. It showed that their rough testability estimate provides enough information and will be used as guidelines for software development.
