According to the characteristics of Intelligent Cloud test system and combining with communication mechanism of general testing platform in practice. In order to realize the fast and effective drive actuator, the design and implementation of the communication module of intelligent cloud test system was introduced on basis of the selenium framework. the communication module use the Carbon-Server as a framework , research intelligent cloud service providers, service providers to the details of the communication, the communication mechanism integrated a large number of single version testing tools and formed a more convenient and distributed development framework. which can better simulate the large-scale network. The results show that the intelligent cloud test communication system have more communication efficiency than the universal test platform in practical engineering.
