The role of software has been increasing in our life day by day. Earlier it was limited to desktops only, but now has reached to the devices that can easily accommodate in our pockets. Nobody can think about a life without the devices controlled by software. Such dependence as well as trust on software compels the software industry to be more conscious and attentive while developing software, so that delivered software became successful in their operational life. On the other hand, it has also been noticed that, in industry most of the development activity is carried out in labor-intensive manner. System developers are also struggling to deliver software with acceptable level of quality, within given resources and time. Such a pressure on the software professionals cannot be ignored as one of the key factor for software whose reliability is not up to mark.
