Component-based usability testing
open-in-new
<p>Component-based usability testing (CBUT) is a testing approach which aims at empirically testing the <a href="/facts/Usability/zuAnqu9Q">usability</a> of an interaction component. The latter is defined as an elementary unit of an interactive system, on which behavior-based evaluation is possible. For this, a component needs to have an independent, and by the user perceivable and controllable state, such as a radio button, a slider or a whole word processor application. The CBUT approach can be regarded as part of <a href="/facts/Component-based_software_engineering/eW5wvSHC">component-based software engineering</a> branch of <a href="/facts/Software_engineering/KX6cE9kz">software engineering</a>. </p>
