CS uses industry-best procedures to ensure that your software’s functional specifications are covered to the fullest extent possible. We have a team that provides independent quality engineering and a wide range of software testing solutions and services to next-generation businesses throughout the world. Functional Testing helps test a system against its functional specifications and requirements outlined. The primary goal of this type of software testing is to validate the application’s outputs against the functional requirements by providing specific inputs. Because the application’s source code is not considered during the testing process, Functional Testing is a black-box testing type.
