We have a RCP application ported from an existing Swing application, so it has reused existing Swing dialogs using AwtEnvironment and existing Swing panels using SWT_AWT bridge. I have been able to hand-code some automation testcases and make them run successfully inside eclipse using Run As -> JUnit Plug-in Test. However, when I am trying to run the same testcases outside eclipse using ant script posted from your site, I found that automation works to the point where the first Swing dialog is supposed to show up. At that point, Swing dialog does not pop up without errors in the log. I am wondering if this is a limitation on eclipse testing framework itself or not, or something we have to change in the ant script to make it work. Thanks for your help on this.
