This results in a forked v or an n model, illustrated in figure 12. Although the proposed model follows the same shape as the traditional testing vmodel developed nearly 3 decades ago, the modified vmodel presented here depicts the unique characteristics of agile development testing. Unlike the waterfall model, in vmodel, there is a corresponding testing phase for each software development phase.
