To reduce testing costs, we propose a model to build highly testable components by embedding testing and monitoring mechanisms inside them. The approach is useful to component developers, who can use these built-in test capabilities in the testing phase, as well as to component users, who can verify whether the component fulfills its contract. Our approach proposes the insertion of built-in mechanisms directly into intermediate code, allowing its use even in COTS components.enText/Conference Paper1617-5468
