    • 本研究旨在將Rapi Recorder記錄的Command-Target-Value型態腳本轉換為Java語言的Selenium程式碼，以提升錄製與回放工具的靈活性和可擴展性。這些工具在自動化測試中具有重要作用，使測試人員能夠迅速錄製並回放測試腳本。然而，由於不同網頁實現中的JavaScript行為差異，這些腳本的回放常面臨挑戰。為了解決這些挑戰，我們設計並實現了一個程式碼生成器（Code Generator），能將Rapi Recorder的99種命令轉換為Selenium程式碼。在實作過程中，我們遇到了諸如元素定位的穩定性、精確還原鼠標移動、動作延遲過長以及選擇最佳測試腳本等問題。本文詳述了解決這些問題的方法，並介紹了程式碼生成器的設計和架構，闡述其中實作的指令解析、狀態管理、後處理和整合的步驟，並通過案例研究展示具體的指令轉換過程。實驗結果表明，我們的方法在提升測試腳本靈活性和效率的同時，保證了其準確性，這為自動化測試提供了一個有效的解決方案。此外，經由跨瀏覽器測試驗證了生成程式碼的兼容性，進一步強化了我們方法的實用性和可靠性。

    This study focuses on converting command-target-value scripts from Rapi Recorder into Selenium code written in Java to enhance the flexibility and scalability of recording and playback tools, which are crucial for automated testing. The varying JavaScript behaviors across different web implementations pose challenges in script replay. To address these challenges, we developed a Code Generator capable of transforming 99 types of commands from Rapi Recorder into Selenium code. We tackled key issues such as element localization stability, precise mouse movement restoration, action delays, and optimal script selection. This paper details the solutions, the design and architecture of the Code Generator, and the processes of command parsing, state management, post-processing, and integration. Case studies are presented to illustrate specific command conversions. Experimental results demonstrate significant improvements in script flexibility and efficiency while maintaining accuracy. Furthermore, cross-browser testing confirmed the compatibility of the generated code, reinforcing the practicality and reliability of our method.
