Testbed
Encyclopedia
A testbed is a platform for experimentation of large development
project
s. Testbeds allow for rigorous, transparent, and replicable testing of scientific theories, computational tools, and new technologies.
The term is used across many discipline
s to describe a development environment
that is shielded from the hazard
s of testing in a live or production environment. It is a method of testing a particular module (function, class, or library) in an isolated fashion. May be implemented similar to a sandbox, but not necessarily for the purposes of security. A testbed is used as a proof of concept or when a new module is tested apart from the program/system it will later be added to. A skeleton framework is implemented around the module so that the module behaves as if already part of the larger program.
A typical testbed could include software, hardware
, and networking components. In software development, the specified hardware and software environment can be set up as a testbed for the application under test. In this context, a testbed is also known as the test environment.

that is shielded from the hazard
Hazard
A hazard is a situation that poses a level of threat to life, health, property, or environment. Most hazards are dormant or potential, with only a theoretical risk of harm; however, once a hazard becomes "active", it can create an emergency situation. A hazard does not exist when it is not...
