White Box Vs Black Box Testing Black box is appropriate at all levels, but dominates higher levels of testing. White box is used predominately at lower levels to compliment black box. White box Testing It examines the basic programming structure. It verifies that the software design is valid or not. In this, software tester has the full knowledge about how the software works, and the tester gets full rights to interact with the scripts. This is also called Structural Testing or Glass Box Testing. In this type of testing, all the statements and conditions are executed at least once. This technique is usually used by the development team. White Box Testing Techniques Following are the various White Box testing techniques: 1. Statement Coverage : In this technique, each and every statement is executed at least once. 2. Decision Coverage : In this technique, all the decision statements are executed at least once. 3. Condition Coverage : In this technique, all decision state

Abstract: This article discusses the challenges in computer systems research posed by the emerging field of ubiquitous computing also called pervasive computing, which is the emerging domain that implements communication technologies into day-to-day life activities. This article provides a classification of the research areas on the ubiquitous computing paradigm. This article also discusses about different waves of computing, its classification and some projects can be implemented. Introduction: Mark Weiser coined the phrase "ubiquitous computing" around 1988, during his tenure as Chief Technologist of the Xerox Palo Alto Research Center (PARC). Both alone and with PARC Director and Chief Scientist John Seely Brown, Weiser wrote some of the earliest papers on the subject, largely defining it and sketching out its major concerns. It is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. In contrast to des
