A common test platform (CTP), also called an open test standard (OTS), is a set of specifications defining test methods for diverse components of computer and electronic systems to be marketed as complete products. The intent of a CTP is to ensure consistency in hardware and software test procedures from the conceptual and design phases through manufacture and distribution.
Computers, computer peripherals and electronic systems often contain complex devices, circuits, programs and interfaces. These must all work together in a variety of applications and conditions. A CTP can be part of an overall quality assurance program. A common standard can reduce the cost of test equipment, optimize the use of available test equipment, increase production efficiency and minimize training costs.
