Operational acceptance testing

Abstract: A systematic approach to organizing the process of determining the operational profile for guiding software development is presented. The operational profile is a quantitative characterization of how a system will be used that shows how to increase productivity and reliability and speed development by allocating development resources to function on the basis of use. Using an operational profile to guide testing ensures that if testing is terminated and the software is shipped because of schedule constraints, the most-used operations will have received the most testing and the reliability level will be the maximum that is practically achievable for the given test time. For guiding regression testing, it efficiently allocates test cases in accordance with use, so the faults most likely to be found, of those introduced by changes, are the ones that have the most effect on reliability. >

Abstract: Testing is an important process that is performed to support quality assurance. Testing activities support quality assurance by gathering information about the nature of the software being studied. These activities consist of designing test cases, executing the software with those test cases, and examining the results produced by those executions. Studies indicate that more than fty percent of the cost of software development is devoted to testing, with the percentage for testing critical software being even higher. As software becomes more pervasive and is used more often to perform critical tasks, it will be required to be of higher quality. Unless we can nd ecient ways to perform eective testing, the percentage of development costs devoted to testing will increase signicantly. This report briefly assesses the state of the art in software testing, outlines some future directions in software testing, and gives some pointers to software testing resources.

Abstract: An approach to software performance testing is discussed. A case study describing the experience of using this approach for testing the performance of a system used as a gateway in a large industrial client/server transaction processing application is presented.

Abstract: Quality assurance and testing organizations are tasked with the broad objective of assuring that a software application fulfills its functional business requirements. Such testing most often involves running a series of dynamic functional tests to ensure proper implementation of the application's features. However, because security is not a feature or even a set of features, security testing doesn't directly fit into this paradigm
