The website consists of a main page with current promotions, a user profile, a gift store and partner pages for registering miles. Before starting direct testing of all the functionality of the site, a voluminous checklist was compiled, including functional, technical and graphic tests of varying degrees of complexity for Windows and Mac OS. The testing itself was carried out in a short time, and during this time the Noveo team managed to check the web application on all browsers, verify the fixed bugs and perform the acceptance testing. At the end of the functional testing, we not only made a detailed report indicating the bugs found, but also offered the customer recommendations for improving the existing application.
