TestAgent: A Framework for Domain-Adaptive Evaluation of LLMs via Dynamic Benchmark Construction and Exploratory Interaction

As large language models (LLMs) are increasingly deployed to various vertical domains, automatically evaluating their performance across different domains remains a critical challenge. Current evaluation methods often rely on static and resource-intensive datasets that are not aligned with real-world requirements and lack cross-domain adaptability. To address these limitations, we revisit the evaluation process and introduce two key concepts: \textbf{Benchmark+}, which extends the traditional question-answer benchmark into a more flexible ``strategy-criterion'' format; and \textbf{Assessment+}, which enhances the interaction process to facilitate deeper exploration and comprehensive analysis from multiple perspectives. We propose \textbf{\textsc{TestAgent}}, an agent-based evaluation framework that implements these concepts using retrieval-augmented generation and reinforcement learning. \textsc{TestAgent} enables automatic dynamic benchmark generation and in-depth assessment across diverse vertical domains. Experiments on tasks ranging from constructing multiple vertical domain evaluations to transforming static benchmarks into dynamic forms demonstrate the effectiveness of \textsc{TestAgent}. This work provides a novel perspective on automatic evaluation methods for domain-specific LLMs, offering a pathway for domain-adaptive dynamic benchmark construction and exploratory assessment.
