The book "Component Based Regression Testing Approaches Without Source Code" offers a comprehensive analysis of regression testing techniques that do not rely on source code. It highlights the challenges testers face when they need to identify changes in modified COTS components. Through a systematic literature review encompassing 32 relevant studies from 1993 to 2010, various approaches to identifying changes are examined. The authors, Nabin Raj Dulal and Sabindra Maharjan, analyze the key features of these approaches and their application in the selection and development of component-based regression testing methods (CBRT). This specialized book is aimed at professionals and researchers in the field of software testing and provides valuable insights into innovative testing methods.
