Design and Implementation of Interface Testing Technique for Better Selection of COTS

Abstract

Commercial Off The Shelf (COTS) components are third party components that are shipped in binary format. They are not provided with their source code, so making changes to them is always difficult. The user is always stuck up with the decision to select COTS components when there are multiple candidates for same requirement. Our approach is based on interface testing that helps the user to select multiple COTS components and run test cases on it. According to the best score of COTS component, the user can select best candidate among them. Our technique is based on using public interfaces of COTS components, so there is no need of source code. This technique can also be used for understanding behavior of COTS components using technique like fault injection.
