||Auto-testing can overcome the shortages, such as environmental supplies or tools which may be under constraint in traditional manual-testing. Besides, auto-testing not only shortens the process time in testing, but also makes the result more precise. Traditional testing process turns into the script file of testing tool, and can save time it. But there isn’t any mechanism which provided to control the script file in the auto-testing platform . Although the same script file can be used for the testing of the same functions in different products in theory, it may fail in practice because of the differences of device under test information which lies in script file.
In the mean time, going into regressing test, however, the more differences in DUT will comes to the same end. So we must re-design the script file in every product, during the long period of testing , it may takes intolerable incalculable time to fix it up.
In order to overcome the shortages, this thesis puts a new item, substitution variables, into testing tools to fix the problem. And , through the increasing of controlling command, it provides the warranty of balance testing. This thesis will put the testing data to prove the main purpose of this thesis .
