Auditing and Decomposing Feedback-Driven Evolution in LLM Test Generation under the Oracle Problem

Yunhao Liang, Chengguang Gan, Ruixuan Ying +3

Execution feedback is often treated as a self-verifying signal for improving LLM-generated tests. However, when generated inputs are executed on a single accepted program and its o…

Security Tests as Executable Specifications for LLM Code Generation: Benefits, Trade-offs, and Coverage Limits

Yunhao Liang, Chengguang Gan, Ruixuan Ying +3

Large language models (LLMs) can generate functionally useful code that remains vulnerable, while security-focused interventions may break intended behavior. We investigate securit…

Do Code Language Models Use Tests? A Behavioral and Representational Study of Test-Driven Code Generation

Yunhao Liang, Chengguang Gan, Ruixuan Ying +3

The paper investigates how code language models respond to test cases in prompts, analyzing whether tests act as executable specifications or merely extra context, and finds that t…

Scaling Test-Driven Code Generation from Functions to Classes: An Empirical Study

Yunhao Liang, Ruixuan Ying, Shiwen Ni +1

Test-driven development (TDD) has been adopted to improve Large Language Model (LLM)-based code generation by using tests as executable specifications. However, existing TDD-style…

Visual Merit or Linguistic Crutch? A Close Look at DeepSeek-OCR

Yunhao Liang, Ruixuan Ying, Bo Li +7

DeepSeek-OCR utilizes an optical 2D mapping approach to achieve high-ratio vision-text compression, claiming to decode text tokens exceeding ten times the input visual tokens. Whil…

HyClone: Bridging LLM Understanding and Dynamic Execution for Semantic Code Clone Detection

Yunhao Liang, Ruixuan Ying, Takuya Taniguchi +2

Code clone detection is a critical task in software engineering, aimed at identifying duplicated or similar code fragments within or across software systems. Traditional methods of…
