Abstract

Fuzz testing explores potential defects in language processors by generating diverse test cases; however, existing approaches based on large language models (LLMs) still exhibit limitations in generating anomalous programs and ensuring test case validity. To address these issues, a general fuzz test case generation method based on historical defect information, named HisFuzz, is proposed, and a prototype system is implemented. The proposed method leverages historical defect data from multiple language processors and employs vectorized retrieval and targeted mutation strategies to guide LLMs in generating test cases with anomalous characteristics. In addition, syntax repair and validity checking mechanisms are incorporated to improve the compilability and execution success rate of generated test cases. During the testing phase, differential testing techniques are used to analyze behavioral discrepancies among language processors. Experimental results on C, C++, Go, and Python language processors demonstrate that HisFuzz outperforms existing approaches in terms of test case validity and code coverage, achieving an average improvement of 20.33% in validity and 32.56% in coverage, while successfully identifying six design defects. These results indicate that HisFuzz can effectively enhance the performance of LLM-based fuzz testing.
