IIOT Testbed 是由中央大學資工系所開發的一個模擬 DDS 應用程式的工具。本研究著重在改善舊有 IIOT Testbed 1.0 使用者介面與利用自動化測試用以保證系統的可靠度,因此我們發展了 IIOT Testbed 2.0 使用者介面與自動化測試的架構。我們的 IIOT Testbed 2.0 是根據 ISO 9241-11 來進行設計。依據使用者的問卷回饋,我們發現 IIOT Testbed 2.0 的可用性比 IIOT Testbed 1.0 好,並提出原因分析。我們也提供了長期自動化測試的結果,用以顯示 IIOT Testbed 2.0 具有高可靠性。;IIOT Testbed is an emulation tool which is developed by National Central University to emulate DDS applications. This study focusses on improving the old IIOT Testbed 1.0 user interface and using automated testing to ensure that system reliability, so we developed the architecture of the IIOT Testbed 2.0 user interface and an automated testing architecture. Our IIOT Testbed 2.0 was designed based on International Organization for Standardization (ISO) 9241-11 standardization. To check the usability aspect, we have taken the questionnaire feedback from the user. Based on that user′s questionnaire feedback, we found that the usability aspect from the IIOT Testbed 2.0 is better than IIOT Testbed 1.0. We have analyzed the results and explain why the IIOT Testbed 2.0 is better than IIOT Testbed 1.0. We also provide the long-term automated testing results to demonstrate the high reliability of the IIOT Testbed 2.0.
