This work focuses on checking the adequacy of the test cases generated using Decision-Table-augmented Event Sequence Graphs (ESG-DTs), which represents the specification of a system under test, by using mutation analysis. Test cases are represented in the Complete Event Sequence (CES) and Faulty CES (FCES) forms. We present a new set of mutation operators for mutation of contracts represented in Multi-Terminal Binary Decision Diagram (MTBDD) and introduce a new approach to mutation of the ESG-DT model by using the proposed mutation operators. The approach is evaluated on three cases. The results show the drawback of specific FCES test sequences and the relationship between the mutant detection by CES/FCES sequences and proposed mutation operators.

Software used in fields such as medicine, finance, aviation and aerospace, nuclear power etc. is required to be reliable. Any software failures in these fields may have catastrophic consequences such as human and financial losses, which may cause a great damage to the economy and to social well-being. Hence, before launching, software should be rigorously tested. Testing can uncover the conditions, which software cannot handle. Those conditions might be overlooked during development. So, software testing points to the faults in the software under development to be patched. The important element of software testing is the use of the adequate test cases. If the outcome of the test case is positive, that means testing did not reveal any fault, then this test case might be considered as inefficient and useless for the tested version of software. Therefore, it is important to check test cases on adequacy, which can be achieved by mutation analysis. This thesis focuses on checking the adequacy of the test cases for Decision-Table-augmented Event Sequence Graphs (ESG-DTs) representation of a system under test by using mutation analysis. Test cases are represented in the Complete Event Sequence (CES) and Faulty CES (FCES) forms. This thesis presents a new set of mutation operators for mutation of contracts represented in Multi-Terminal Binary Decision Diagram (MTBDD). This thesis introduces a new approach for mutation of the ESG-DT model by using the proposed MTBDD mutation operators. The proposed approach is evaluated on three cases. The results for all cases show the drawback of specific FCES test sequences and the relationship between the mutant detection by CES/FCES sequences and proposed mutation operators.

The Design by Contract technique allows developers to improve source code with contracts, and testing using contracts helps to identify faults. However, the source code of the program under test is not always available. With black-box testing, it is possible to generate contracts from specifications of the software. In this paper, we apply mutation analysis on a model of a given specifications, where mutants are initially gained by applying proposed in this paper certain mutation operators on corresponding model, and then mutated specifications are examined.
