    Mutation-Based Minimal Test Suite Generation for Boolean Expressions
    (World Scientific Publishing, 2023) Ayav, Tolga; Belli, Fevzi
    Boolean expressions are highly involved in control flows of programs and software specifications. Coverage criteria for Boolean expressions aim at producing minimal test suites to detect software faults. There exist various testing criteria, efficiency of which is usually evaluated through mutation analysis. This paper proposes an integer programming-based minimal test suite generation technique relying on mutation analysis. The proposed technique also takes into account the cost of fault detection. The technique is optimal such that the resulting test suite guarantees to detect all the mutants under given fault assumptions, while maximizing the average percentage of fault detection of a test suite. Therefore, the approach presented can also be considered as a reference method to check the efficiency of any common technique. The method is evaluated using four well-known real benchmark sets of Boolean expressions and is also exemplary compared with MCDC criterion. The results show that the test suites generated by the proposed method provide better fault coverage values and faster fault detection.

    Mutation Analysis of Specification-Based Contracts in Software Testing [conference Object]
    (IEEE, 2021) Khalilov, Abbas; Tuğlular, Tuğkan; Belli, Fevzi
    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.
