Abstract:As software implementation technology is more and more complicated functions, software testing is an urgent need to have automation, multi-platform, small cost of test automation framework, the emergence of the STAF solves this problem very well.In this paper, a test automation framework based on STAF, and simulated practice, USES the ATT tool design automatic test engine, through the simulation test, build test automation framework based on STAF.Test results show that under the different environment, the framework is a high degree of automation of software test, high test efficiency and the advantages of easy to manage, maintain and extensible.
