Title: Evaluating LLM-Based Test Generation Under Software Evolution
Abstract:
arXiv:2603.23443v1 Announce Type: cross Abstract: Large Language Models (LLMs) are increasingly used for automated unit test generation. However, it remains unclear whether these tests reflect genuine reasoning about program behavior or simply reproduce superficial patterns learned during training. If the latter dominates, LLM-generated tests may exhibit weaknesses such as reduced coverage, missed regressions, and undetected faults. Understanding how LLMs generate tests and how those tests respo
