End-to-end (E2E) testing is the cornerstone of ensuring web application quality. It simulates real user interactions, verifying that all application components seamlessly work together. However, traditional E2E testing methods present significant challenges. Manual test creation is a time-consuming and resource-intensive process. Existing automated methods often generate random tests that lack the focus and relevance of human-designed scenarios, missing critical features and their interplay. Imagine building tests that intuitively understand the functionalities of your web application, replicating how users interact with its features. This is the promise of a novel, feature-based approach to automated E2E testing. By understanding the very essence of how users engage with your app, this approach creates targeted, intelligent tests. This new research formalizes the concept of "feature-driven" E2E testing and introduces AUTOE2E, a cutting-edge technique using Large Language Models (LLMs) to generate comprehensive, feature-driven test cases. AUTOE2E intelligently infers features within a web application by observing user actions. This allows the system to learn from how users interact with the application, deducing its key features and then converting those features into executable test scenarios. Furthermore, the researchers address a critical gap in the research community by introducing E2EBENCH, a new benchmark for automatically assessing the feature coverage of E2E test suites. This benchmark allows for standardized and objective evaluation of automated testing techniques, driving further innovation and improvement. Evaluation on E2EBENCH demonstrates AUTOE2E's significant advantage. It achieves an average feature coverage of 79%, outperforming the best baseline by an impressive 558%. AUTOE2E also excels in creating more complex test cases that reflect the intricate user journeys within today's web applications. The future of web application testing is feature-driven. AUTOE2E's approach, along with the development of the E2EBENCH benchmark, provides a solid foundation for revolutionizing how E2E tests are designed, developed, and assessed. By understanding and targeting features, we unlock a new level of testing automation, resulting in higher quality web apps and a more efficient development process. While there are further avenues for improvement, such as handling multiple test cases per feature and refining assertion generation, this research marks a significant step toward truly intelligent test automation.

Question & Answers
How does AUTOE2E utilize Large Language Models to generate feature-driven test cases?
AUTOE2E employs LLMs to analyze and understand user interactions with web applications to create targeted test cases. The system works by first observing user actions to infer key features, then translates these observations into executable test scenarios. The process involves: 1) Feature inference through user interaction analysis, 2) Pattern recognition of common user workflows, 3) Translation of identified features into structured test cases, and 4) Generation of executable test code. For example, in an e-commerce application, AUTOE2E would observe the checkout process, identify essential features like cart management and payment processing, and automatically generate comprehensive tests covering these critical user journeys.
What are the benefits of automated end-to-end testing for website reliability?
Automated end-to-end testing helps ensure websites function reliably by simulating real user interactions across all components. Key benefits include reduced manual testing effort, consistent quality verification, and faster detection of issues before they reach users. For businesses, this means lower maintenance costs, improved user experience, and faster deployment cycles. For instance, an e-commerce site can automatically verify that customers can browse products, add items to cart, and complete purchases without errors, ensuring smooth operations 24/7. This approach is particularly valuable for companies with complex web applications that require frequent updates and maintenance.
Why is feature-based testing important for modern web applications?
Feature-based testing is crucial because it focuses on validating the actual functionalities that users interact with, rather than just technical components. This approach ensures that testing efforts align with real user experiences and business requirements. Benefits include better test coverage of critical features, more efficient resource utilization, and higher confidence in application quality. For example, a social media platform would focus on testing key features like post creation, user interactions, and content sharing - the elements that directly impact user experience. This targeted approach helps companies maintain high-quality applications while optimizing testing resources.
