Testing Java Swing-based applications

Testing applications with a graphical user interface can be done in several ways, with the most important being by generating events for the event queue. This paper reports on the issues involved in this for Java applications that use Swing (or JFC) objects for their user interface. It also describes the replayJava system, which can be used to record and playback user sessions or can be used to directly generate a session. The resulting state of the application can then be checked for correctness.
