error seeding

error seeding: The process of intentionally adding known defects to those already in the component or system for the purpose of monitoring the rate of detection and removal, and estimating the number of remaining defects. [IEEE 610] defect masking or fault masking: An occurrence in which one defect prevents the detection of another testware: Artifacts produced during the test process required to plan, design, and execute tests, such as documentation, scripts, inputs, expected results, set-up and clear-up procedures, files, databases, environment, and any additional software or utilities used in testing. [After Fewster and Graham]. As we know the hardware engineer produce hardware,software engineers produce software ,same like this ,software test engineer produce testware It is a static approach in whicj doc. . are being review but not executed It is a dynamic approach in which we validate the application Open issue: it is a agreement between ba and client where the application is release with open defect s which doe’snt effect the functionality of the application
