Requirements based testing of software

Testing is the method that assures that the developed system conforms to the specification and no error arises during system usage. No system is deployed without testing as testing produces confidence in the system. This paper presents the Requirements Based Testing (RBT) technique for testing the Usability and Functional Requirements of a software. The main emphasis of this paper is to test the usability of a software, as being a non-functional requirement that is perceived subjectively it is difficult to measure it. A generic template has been proposed for testing usability. For the purpose of evaluation, this method is applied to test a software named “Programming Teaching Aid”, a system that helps students in understanding the programming language C++.
