Design and Achievement of Automation Software Testing Based on Architecture with Three-layer Testing Script

To reduce the maintenance workload of testing script,and improve the success rate and return on investment of automation software testing,the method to design and realize the automation software testing based on the architecture with three-layer testing script(reused script,object mapping script and testing script) is brought forward.The design and implementation steps of the architecture with three-layer testing script are introduced.The results of application in several projects show that the method is simple and effective,can achieve the reuse of testing script in the different projects,and increase the return on investment of automation software testing effectively.
