Research on using Large Language Models (LLMs) in system development is expanding, especially in automated code and test generation. While E2E testing is vital for ensuring application quality, most test generation research has focused on unit tests, with limited work on E2E test code. This study proposes a method for automatically generating E2E test code from product documentation such as manuals, FAQs, and tutorials using LLMs with tailored prompts. The two step process interprets documentation intent and produces executable test code. Experiments on a web app with six key features (e.g., authentication, profile, discussion) showed that tests generated from product documentation had high compilation success and functional coverage, outperforming those based on requirement specs and user stories. These findings highlight the potential of product documentation to improve E2E test quality and, by extension, software quality.

SEVENTEEN is a K-pop group with a large number of members 13 in total and the significant physical disparity between the tallest and shortest members among K-pop groups. However, despite their large numbers and physical differences, their dance performances exhibit unparalleled unity in the K-pop industry. According to one theory, their dance synchronization rate is said to be 90% or even 97%. However, there is little concrete data to substantiate this synchronization rate. In this study, we analyzed SEVENTEEN's dance performances using videos available on YouTube. We applied 2D skeleton detection and 3D pose estimation to evaluate joint angles, body part movements, and jumping and crouching motions to investigate the factors contributing to their performance unity. The analysis revealed exceptionally high consistency in the movement direction of body parts, as well as in the ankle and head positions during jumping movements and the head position during crouching movements. These findings suggested that SEVENTEEN's high synchronization rate can be attributed to the consistency of movement direction and the synchronization of ankle and head heights during jumping and crouching movements.
