Table 1: Evaluation table of proposed approaches Authors / Year Behavior models Tools used to support Problem Discussed Strengths LimitationsSarma et al. /2007 Sequence and Class Diagram Magic Draw V 10.0, IBM Rational Rose Automatic generation of test cases from UML models focuses on structural and behavioral design in the test case generation process. Also, deal with interaction flaws and scenario flaws. • The strength of this method is that it can handle a large project efficiently. • Better integration with test case generation activities. • The technique is not sufficiently automated. • Lack of quality requirements test management. Shen et al. /2007 state diagrams Undefined Testing object-oriented systems… • The advantage of this method is that it is reasonably effective to use the profile as a source for dividing into different levels. • Better integration of the test case with the behavior model • The approach is lacking in managing quality requirements tests • Behavior modeling can become very complex when the mentioned approach is implemented on large-scale systems and can eventually produce inconsistent results. Monalisa Sarma, Rajib Mall /2007 Sequence Diagrams, Class Diagram Magic Draw V 10.0, IBM Rational Rose Covers operational errors, use case dependency errors and interaction errors as well as scenario errors with the help of UML behavioral models • Address the challenges created by the object-oriented paradigm. • Early generation of test cases • Significantly reduced errors and helps early error detection • Inconsistent selection of test cases from UML models can cause the system to generate an operational bug if each use case does not follow the input-relationships desired output.• Errors ca...... middle of the paper ......reliability engineering[12 ] Liping Li1, Huaikou Miao1, Zhongsheng Qian1, “A UML-Based Approach to Testing Web Applications” in the Symposium International Conference on Computer Science and Computational Technology in 2008[13] Xi Wang, Liang Guo, Huaikou Miao, “An Approach to Transforming UML Model to FSM Model for Automatic Testing” in 2008 International Conference on Computer Science and Software Engineering[ 14] Scenarios" in 2009 UKSim Third European Symposium on Computer Modeling and Simulation[16] Ashalatha Nayak, Debasis Samanta "Model-based Test Case Synthesis Using UML Interaction Diagram" http://doi.acm.org/
