The stories of non-functional requirements are examined, and acceptance parameters are defined, in order to solve these quality challenges. It is also essential to evaluate the developed system against the desires of the customer to increase customer satisfaction. The proposed chapter lays out the various ways of gathering functional and non-functional requirements and testing them in the context of agile ...
