A test bench or testing workbench is a virtual environment used to verify the correctness or soundness of a design or model, for example, a software product. The term has its roots in the testing of electronic devices, where an engineer would sit at a lab bench with tools for measurement and manipulation, such as oscilloscopes, multimeters, soldering irons, wire cutters, and so on, and manually verify the correctness of the device under test (DUT). In the context of software or firmware or hardware engineering, a test bench refers to an environment in which the product under development is tested with the aid of software and hardware tools. The suite of testing tools is often designed specifically for the product under test. The software may need to be modified slightly in some cases to work with the test bench but careful coding can ensure that the changes can be undone easily and without introducing bugs. 〔http://www.marilynwolf.us/CaC3e/〕 == Components of a test bench == A test bench has four components: #Input: The ece criteria or deliverables needed to perform work #Procedures to : The tasks or processes that will transform the input into the output #Procedures to check: The processes that determine that the output meets the standards #Output: The exit criteria or deliverables produced from the workbench 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Test bench」の詳細全文を読む スポンサード リンク
