Theoretical and Empirical Analyses of the Effectiveness of Metamorphic Relation Composition

Metamorphic Relations (MRs) play a key role in determining the fault detection capability of Metamorphic Testing (MT). As human judgement is required for MR identification, systematic MR generation has long been an important research area in MT. Additionally, due to the extra program executions required for follow-up test cases, some concerns have been raised about MT cost-effectiveness. Consequen...
