Regression testing is an important activity in software maintenance. Although a number of existing research results have addressed the problems and solutions in regression testing of traditional programs, no research results have focused on the issues and solutions in regression testing of object-oriented programs. In this paper, we present a method for(More)
Regression testing is an important activity in software maintenance. Although a number of studies have addressed the problems and solutions in regression testing of traditional programs, no studies have focused on the issues and solutions in regression testing of object-oriented programs. In this article, we discuss various types of code changes of classes(More)
The complexity and interdependencies of an object-oriented program makes testing of such programs diicult. In this paper, we present a reverse engineering based model called Object Relation Diagram (ORD), which is generated from analyzing the C++ source code of an object-oriented program. An ORD is a directed graph in which the vertices represent the object(More)
Types of code changes in an object oriented library are described. A formal model for capturing and inferencing on the changes to identify aaected classes is described. The model consists of three types of diagrams: the object relation diagram (ORD), the block branch diagram (BBD), and the object state diagram (OSD). An ORD describes the inheritance,(More)
The object-oriented (OO) paradigm is rapidly gaining acceptance in the software industry. However, the powerful features of this new paradigm also introduce a new set of OO software testing and maintenance problems. The pioneering work in identifying these new problems includes [7, 10-12, 14, 16, 18]. The problems can be summarized as: 1) the understanding(More)
Recently, the extraordinary growth in the World Wide Web has been sweeping through business and industry. Many companies have developed or integrated their mission critical applications using Web technologies. As Web applications become complex, testing Web applications becomes crucial. This paper extends traditional data flow testing techniques to Web(More)
