An error-specific approach to testing
The main objective of software testing in the software development life cycle is to verify conformance of the implemented software with its intended requirements. Such requirements include system requirements, and programming requirements. Non-conformance with such requirements causes what are known as software errors. Specifying an appropriate testing strategy to expose software errors is still an art. Traditional approaches do succeed in revealing many errrors but none is powerful enough to expose all errors. The best that is hoped for is to use a specific test strategy to expose a specific error type in specific program locations. This limitation is exploited to develop a new approach to software testing which is called an error-specific testing (EST) strategy. Error specific testing is in fact a dual to the traditional testing approaches.
