Quality Assurance and Quality Control
Within this stage we test the functionality of the site; eliminate possible errors and defects; make corrections in modules in case needed; check implementation in various browsers.
The quality assurance process includes the check of all requested functionality. Each module is tested separately, in combination of other modules, and then integrated in the system. Tests determine whether the resulting functionality fulfills the specified requirements and suits the quality criteria. The web-application is also tested in different web browsers for adequate compatibility.
