New benchmark reveals LLM agents struggle with behaviorally adequate test generation

Researchers have introduced Req2Test-Bench, a new benchmark designed to evaluate the ability of large language model agents to generate behaviorally adequate tests from software requirements. The benchmark comprises over 5,000 execution-validated instances from eight open-source projects, pairing natural-language requirements in Gherkin with their corresponding developer-written test implementations. Initial evaluations showed a significant gap between generating tests that execute successfully and those that are behaviorally adequate, with the top-performing configuration achieving only 33.8% behavioral adequacy despite an 82.8% execution success rate. AI

IMPACT Highlights a critical gap in LLM agent capabilities for software testing, suggesting current models are insufficient for generating behaviorally adequate tests without human oversight.

    Benchmarking LLM Agents for Behaviorally Adequate Test Generation from Software Requirements

    arXiv:2610.36584v1 Announce Type: cross Abstract: As large language model agents increasingly compile natural-language requirements into repository-level code, requirement-to-test generation grows in importance to provide validation constraints (or harness) to guide code generati…
