Traffic Internet-of-Things testing method based on fault simulation

The invention discloses a traffic Internet-of-Things testing method based on fault simulation. The traffic Internet-of-Things testing method is characterized in that a testing machine is connected to a tested system through a network switching device and gateway devices, and the testing machine executes the following steps: (1) a traffic Internet-of-Things simulation environment is built; (2) simulation testing data are generated, and on the basis of the built traffic Internet-of-Things simulation environment, the simulation testing data under the normal condition and the simulation testing data under the fault condition are generated; (3) testing is carried out, a testing script transmits the simulation testing data generated in the step (2) to the tested traffic Internet-of-Things system through the network switching device and the gateway devices, collects the operation result of the tested system and returns the operation result to the testing machine through the network switching device and the gateway d
