An empirical study of test cases in software testing

Software is a set of instructions executed by a computer which are designed to perform a particular task. Software Development Life Cycle is used to develop the software. Software Testing is the important phase of software development life cycle (SDLC). Software testing is a part of SDLC. Testing fulfills the customer´s requirement. In addition to that testing process finds and removes the bugs of the software. Developing organization tries to show that the software they developing is quality software and process used to develop as well as to test software are quality processes. To test any software, tester writes test cases based on Software Requirement Specification (SRS). SRS contain all the functional and non-functional requirements of the software. Individual component (Unit) requirement specifications are written in detail. Test engineer and / or Tester used SRS to write test cases. Test cases are used to test the software thoroughly in manual testing. All small loop holes of the software could be identified by test cases. This paper focus on the significance of test cases and their role to test software used in IT industries. The researcher has concluded that without test cases testing would not be possible.
