Today's World Is Object Oriented. In This Object Oriented World, We Have Object-Oriented Languages, Object-Oriented Analysis, Deigning, and Testing of Softwares. from History, the Foremost Popular Object-Oriented Modeling Approaches Are Rumbaugh's Object Modeling Technique (Omt), Which Was Better For Object-Oriented Analysis (Ooa), and Grady Booch's Booch Method Which Was Better For Object-Oriented Design (Ood). In 1994 Omt and Booch Method Were Unified into Unified Modeling Language (Uml). Later On, In 1996, Object-Oriented Software Engineering (Oose) Also Unified With Uml.Uml Has Synthesized the Notation of Booch Method, the Object Modeling Technique, and Object-Oriented Software Engineering By Fusing Them into Single and Widely Usable Modeling Language. Object-Oriented Testing Remains Separate. Therefore the Thrust Behind This Paper Is to Integrate Object-Oriented Testing With Uml.
