Learn how to evaluate LLM-based regression test generation for automated software engineering and improve your testing workflow

advanced Published 7 Jul 2026
Action Steps
  1. Run an LLM for a few minutes to generate regression tests after a code change
  2. Configure your CI/CD pipeline to integrate LLM-based test generation
  3. Test the generated regression tests to ensure they exercise the code change effectively
  4. Apply LLM-based test generation to programs with highly structured inputs
  5. Compare the effectiveness of LLM-based test generation with traditional testing methods

Title: Evaluating LLM-Based Regression Test Generation

Abstract:
arXiv:2501.11086v2 Announce Type: replace-cross Abstract: Large Language Models (LLMs) have shown tremendous promise in automated software engineering. In this paper, we investigate LLMs for just-in-time regression test generation for programs, like parsers, interpreters, or compilers, that take highly structured, human-readable inputs. When a bug fix or code change is committed, the repository (as part of CI/CD) runs an LLM for a few minutes to generate regression tests that exercise the change
