I am writing a TotalCommander-like application. I have a separate component for file list, and a model for it. Model support listeners and issues a notification for events like `CurrentDirChanged` etc. in following manner:

```

private void fireCurrentDirectoryChanged(final IFile dir) {
    if (SwingUtilities.isEventDispatchThread())
        for (FileTableEventsListener listener : tableListeners)
            listener.currentDirectoryChanged(dir);
    else {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                for (FileTableEventsListener listener : tableListeners)
                    listener.currentDirectoryChanged(dir);
            }
        });
    }
}

```

I've written a simple test for this:

```

@Test
public void testEvents() throws IOException {
    IFile testDir = mockDirectoryStructure();
    final FileSystemEventsListener listener = 
                context.mock(FileSystemEventsListener.class);
    context.checking(new Expectations() {{
        oneOf(listener).currentDirectoryChanged(with(any(IFile.class)));
    }});

    FileTableModel model = new FileTableModel(testDir);
    model.switchToInnerDirectory(1);
}

```

This does not work, because there is no `EventDispatchThread`. Is there any way to unit test this inside the headless build?
