In software engineering, we have many problems particularly with software cost estimation and the assessment of the evaluation model. Software cost estimation mainly depends on two factors which are the estimation consistency and estimation accuracy. These are very much important to the perfect development of the software without any drawbacks to it. In the past there have been many models and techniques that have failed to give the correct software estimation that really challenges the all factors of perfect software in this paper we use software requirement specification but we were not getting the accurate results that are helpful for developing of perfect software that is having perfect cost estimation. So we introduce the Automated Test-Data Generation Techniques method that gives us the desired results which will be helping us to know the software cost estimation very much accurately and also estimate consistently.
