As shown in fig. 1, an automated test intermediate interface method and platform based on a cloud architecture are disclosed, wherein an integrated test instrument driving interface is designed and integrated, instrument driving is unified from an application layer to form a universal instrument driving assembly, and the interchangeability of hardware of multiple manufacturers can be conveniently realized through the driving interface design. In the past, instrument hardware driving is realized on the basis of a standard instrument interface, the standard instrument interface standard is generally established on a protocol and a command set at a lower layer, and with the rapid development of a physical communication technology, the cultivated test instrument is not driven through the standard instrument interface, and serious diversification occurs on the driving interface. So that higher integration automated testing should be more focused on the interchange of meter devices at the application level than on the underlying command set. The invention can effectively solve the problem that the application built on the universal instrument driver only makes a channel with high-level methods and attributes, such as writing instructions, reading states and obtaining results, but does not make a channel with specific instructions of the instrument, and instrument equipment of different manufacturers only has a universal method of reading and writing, so that the instrument can be replaced on the application level on our platform. Therefore, on a new platform, the internet of things testing system based on the cloud architecture can be suitable for instrument equipment supporting various protocols, including instrument equipment supporting standard instrument equipment interface drive, native instrument drive, own product drive and other modules.
