    METARO3: Metamorphic Relation Group for Automatic Program Repair

    Tingting Wu1, Yunwei Dong1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.121, No.3, pp. 909-928, 2019, DOI:10.32604/cmes.2019.07809

    Abstract The application of metamorphic testing (MT) on automatic program repair (APR-MT) is used to generate a patch without test oracles by examining whether the input metamorphic relation (MR) is satisfied or not. However, the delivered patch is plausible since it may satisfy the input MR but violate other MRs. This inspires us to propose an improved approach to enhance the effectiveness of APR-MT with metamorphic relation group. Our approach involves three major steps. First, we formally define the repair process of APR-MT by building the model of automatic program repair and metamorphic testing separately. Then, we propose the advanced model… More >
