Testing is performed by different types of strategies. Generally testing is performed on code, but if the software can be tested in the earlier phases then most of the errors can be eliminated and can be stopped from propagating to next phase. The proposed work presents a novel design based testing approach that can fix errors in initial phase. To perform design based testing, we need a language that can deal with the design ably i.e. Unified Modeling Language (UML). UML, which supports object-oriented technology, is widely used to describe the analysis and design specifications of software development. UML models are an important source of information for test case design. UML activity diagrams describe the realization of the operation in design phase and also support description of parallel activities and synchronization aspects involved in different activities perfectly. However UML Sequence diagram describes the way in which different objects interacts with each other, sequence of message passing between different objects. And Class diagram identifies the different classes, its attributes and operations respectively. We propose a method to generate test cases using UML activity diagram. Next, we propose a novel approach to generate test cases from test scenarios using UML activity, sequence and class diagram. First we generate xml from UML diagram. UML consists of different designs that are used to specify the static and dynamic behavior of the software. Proposed system focuses on three diagrams viz. class, sequence and activity diagrams. The class diagrams help us to generate static test cases and the sequence and activity diagrams give dynamic test cases and integrity test cases.
