“…Research have shown that a testing can be incremental, which means that after development of every chunk,we have to test the phase. Its importance is reflected in A. Mohsenzadeh et al [20], V. Lelli Dantas [15], D. Kovachev et al [2], L. Murugesan [10], Yonggang Wen et al [6],Performance of a mobile related applications can be improved day by day using different models and techniques that will lead the mobile computing to a much higher level.Many researches have been done for this purpose such as described in N. [18].The great benefit of cloud computing is to transfer a data easily over a wireless medium that gives the attribute of mobility to it and has been discussed by Y. Wen et al [6] ,F. Lins et al [17], D. Sahu et al [19], A. Mohsenzadeh et al [20], C. Shravanthi et al [17].The priority of the paremeters included in table 1 may varies depending upon the scenario in which that application is going to run for example if a device is doing a wireless communication ,mobility parameter will have the higher priority than the device which is just storing the data over the data cloud.Flexibility is a factor that can be defined as elasticity in proving better services in order to accommodate users.Surveying different papers,it has been analyzed that some of the papers discusses the issue of flexibility such as in N.Fernando et al [1],D.Kovachev et al [2], Shih-Hao Chang et al [5],Lins1 et al [7], K.Pousttchi et al [9], L.Murugesan et al [10],S.Abolfazli et al [12],A.KBamdra et al [13],V.Lelli Dantaset al [15],K.AKamaruddin [18],A. Mohsenzadeh et al [20]..Researches have been done to reduce flaws in the the previous systems.…”
