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.
