Journal of Digital Information Management Hina Sattar, Imran Sarwar Bajwa, Umar Farooq Shafi 13 5 2015 http://dline.info/fpaper/jdim/v13i5/v13i5_4.pdf Software development life cycle is systematic way of developing software which describes phases of the software development and the sequence in which these phases are executed. Each phase generates deliverables required by the next phase in the life cycle. Requirements are translated into design. Code is produced according to the design which is called development phase. After coding and development the testing verifies the deliverable of the implementation phase against requirements. Almost all software development models contain software testing as one phase but testing require at each phase of SDLC. Different testing technique can apply on different phases based on software quality attributes. Software testing majorly categorized in to functional and structural testing each of them focus on different aspect of software. Both play vital role in software development life cycle by assuring software quality, each of them can use to measure different quality attributes. Since, both structural and functional testing faces a lot of challenges during manual conduction .Focus of this research paper is to find out significance of structural testing in SDLC along with challenges of structural testing methodology “DD path testing” in manual environment and suggest suitable solution to face these challenges. Suggested solution describes which steps involve in DD path testing and how they can automate.
