Abstract: “Within the automated testing world there are two predominating testing methodologies: black-box and white-box. This paper seeks to explore the pros and cons of both approaches and to identify when each approach should be used to ensure quality applications are delivered to market. In the end, this paper concludes that while black-box testing has its drawbacks in the past, innovative approaches to black-box testing makes it the likely choice to deal with the ever increasing complexity of applications and deliver lower Total Cost of Ownership (TCO) and a better Return on Investment (ROI) to organizations although it can be used with a degree of white box testing involved in it.”
