Marathon is a general-purpose tool for both running and authoring acceptance tests geared at the Java Platform Version 1.3 or later. Included with marathon is a rich suite of components to help you interact with your application at the User interface Level (GUI). To aid with the regression testing of existing applications, Marathon comes bundled with a recorder to capture events as you use and interact with your application. These events are then converted into a valid Marathon test, which can subsequently be played back.
