The process of manual testing requires a tester to put himself into the shoes of an end user, and use/test the application through his eyes. The aim thereby is to find as many defects (Bugs) as possible and in this way contribute to the flawless functionality of the application. In the course of this, it is necessary to follow a written test plan that leads through a set of important test cases which guarantees that all features of the application are tested, as well as the correct behavior and the completeness of testing. We at Rocket-Testtailor, have a set of professional testers who have experience in testing applications thoroughly and who understand the importance of the user-perspective. We offer a wide range of different tests (black-, white- or grey-box testing), to ensure the discovery of quantitatively and qualitatively high number of bugs.
