I need to write some end-to-end tests for a Swing GUI application, likely running on Linux. Note that these are not unit tests. I am not testing through the API. Rather I am launching the application (in this case IntelliJ IDEA with our plugins installed) and select menu items, press buttons, read the screen, and so forth.
What tools are folks using for this? Open source strongly preferred (since the plugins we’re testing are open source) but this is not absolutely required.
