In this paper, the authors suggest that the combination of state-transition graph and cause-effect graph is an excellent solution of test oracles problems. The empirical setup for ‘Student admission process’ presented in this paper has been implemented to encourage test results. The suggested approach contains UML and OCL architectures, as input in which the combination of state-transition graph and cause-effect graph are converted into state table and decision tables and its fusion creates an innovation i.e. “State-decision table” has been created to serve as input for generating test cases.
