Abstract: In recent years, the rise of cloud computing technology was favored for its superior computing power, ondemand resources, charging by volume or time and other characteristics. While at the same time, the traditional software testing techniques still plague many enterprises for the high cost and low efficiency problems. So to migrate software testing to cloud computing environment has become welcomed. In this paper it briefly introduced the basic definition and characteristics of cloud testing, elaborated the framework of cloud testing platform and improved the dynamic scheduling algorithm. In the end, the emulation experiments prove the effectiveness of this algorithm by CloudSim a cloud computing emulator.

Key words: cloud computing, cloud testing, framework, scheduling algorithm
