DiffuTester: Accelerating Diffusion LLM Unit Test Generation via Structural Pattern Mining

DiffuTester is a training-free framework that accelerates diffusion language model unit test generation by mining shared structural patterns across test cases via AST, enabling more tokens per denoising step and achieving 2–3× speedup while maintaining coverage across Python, C++, and Java on DiffuCoder and Dream models.
