David Herron of Sun’s Java SQE (Quality Engineering) has been running several posts on Java UI testing and wrote this TestingGUIApplications page. From discussing this with customers it appears that QFTestJUI is a very nice commercial tool.
Note to self: look at jemmy, start here (preso and code included).
More Swing testing considerations here. A pretty nice case for scripting.
BTW, some scripting news in NetBeans real soon now I hear. Stay tuned.
