Automated Web Application Testing: End-to-End Test Case Generation with Large Language Models and Screen Transition Graphs
🤖 AI Summary
Web applications exhibit high interface dynamism and complex navigation and form interactions, posing significant challenges for end-to-end test case generation—particularly low coverage and poor robustness. To address this, we propose a navigation modeling approach that integrates screen transition graphs with large language models (LLMs) to enable high-precision path exploration. We further design a state-graph-based automated testing framework for conditional forms, supporting dynamic DOM parsing and interaction modeling. Additionally, we construct the first dedicated benchmark dataset for form-interaction testing. Experimental evaluation across diverse, complex web applications demonstrates substantial improvements in test coverage and path discovery accuracy—especially for branching navigation and conditional form-filling tasks. Our approach establishes a scalable, empirically evaluable paradigm for web application reliability testing.

📝 Abstract
Web applications are critical to modern software ecosystems, yet ensuring their reliability remains challenging due to the complexity and dynamic nature of web interfaces. Recent advances in large language models (LLMs) have shown promise in automating complex tasks, but limitations persist in handling dynamic navigation flows and complex form interactions. This paper presents an automated system for generating test cases for two key aspects of web application testing: site navigation and form filling. For site navigation, the system employs screen transition graphs and LLMs to model navigation flows and generate test scenarios. For form filling, it uses state graphs to handle conditional forms and automates Selenium script generation. Key contributions include: (1) a novel integration of graph structures and LLMs for site navigation testing, (2) a state graph-based approach for automating form-filling test cases, and (3) a comprehensive dataset for evaluating form-interaction testing. Experimental results demonstrate the system's effectiveness in improving test coverage and robustness, advancing the state of web application testing.
