Abstract
This paper presents the advantages of using a Stimulus Response Requirements Specification (SRRS) technique to reduce costs, development time, and errors in the generation of system level test cases in comparison to using a Structured Analysis (SA) technique. A SRRS technique describes requirements in terms of externally visible inputs (stimuli), processing, and externally visible outputs (responses). The SRRS techniques include Use Cases and Scenario driven techniques. This paper first reviews a basic process for developing system test cases. An example from a library system is used to illustrate the first step of this process with a conventional SA requirements specification and a SRRS. The use of a SRRS technique to document the requirements specification simplifies the test case generation process by eliminating the first step in the three step process. Download Postscript
