摘要：Testing and debugging have always been the most time-consuming parts of the software development procedure and require large amounts of human resources. When a bug is located, manually fixing it to repair the buggy program is still a difficult and laborious task for developers. Hence automatic program repair techniques, especially the test-based approaches, have drawn great attentions in recent years. Researchers have explored and proposed various novel methods and tools, pushing the idea closer to reality. In this paper, we systematically survey the work in mainstream of test-based program repair (TBR) and discuss the properties automatically generated patches should have. We classify the state-of-the-art approaches for TBR, and evaluate their strengths and weaknesses according to their functional mechanisms. Finally, we refer to some empirical results and propose four important issues, which are supposed to be critical and constructive in this research area.
