Research and implementation of automated function test in iterative development model

Now in the iterative development model,because of the component or the function frequently change,make the function testing case easily to out of used,especially,function testing automation is to be difficult to maintain and come true.As a result tests poor efficiency,extension development cycle and unable effective guarantee of software quality.A deep analysis of iterative development and functional testing is given.And pre-testing is introduced into functional testing and an automatic testing framework is realized.Under the management of the framework,development,manual testing,and automatic testing can be worked on assemble,at last verified the usability and effectiveness of the framework in the real development process.
