So I think this is the problem. The Right Fix I think is to:

1. Declare these methods in ui/views/cocoa/views_nswindow_delegate.h
2. Assert that [window delegate] is a ViewsNSWindowDelegate (if this wasn't true
this test wouldn't pass on 10.6)
3. Cast the pointer to ViewsNSWindowDelegate, and call the method there directly

1. I declared the relevant methods in ui/views/cocoa/views_nswindow_delegate.h.
2. This test doesn't run on OSX 10.6, so I left out the assert.
3. I used base::mac::ObjCCast.

   id window_delegate = [window delegate];
-  [window_delegate windowDidFailToEnterFullScreen:window];
+  [window_delegate performSelector:@selector(windowDidFailToEnterFullScreen:)
+                        withObject:window];
   EXPECT_FALSE(bridge()->target_fullscreen_state());
 
   // Now perform a successful fullscreen operation.
   [center postNotificationName:NSWindowWillEnterFullScreenNotification
                         object:window];
   EXPECT_TRUE(bridge()->target_fullscreen_state());
   [center postNotificationName:NSWindowDidEnterFullScreenNotification
                         object:window];
   EXPECT_TRUE(bridge()->target_fullscreen_state());
 
   // And try to get out.
   [center postNotificationName:NSWindowWillExitFullScreenNotification
                         object:window];
   EXPECT_FALSE(bridge()->target_fullscreen_state());
 
   // On a failure, Cocoa sends a failure message, but then just dumps the window
   // out of fullscreen anyway (in that order).
-  [window_delegate windowDidFailToExitFullScreen:window];
+  [window_delegate performSelector:@selector(windowDidFailToExitFullScreen:)
+                        withObject:window];
   EXPECT_FALSE(bridge()->target_fullscreen_state());
   [center postNotificationName:NSWindowDidExitFullScreenNotification
                         object:window];
   EXPECT_EQ(1, [window ignoredToggleFullScreenCount]);  // No change.
   EXPECT_FALSE(bridge()->target_fullscreen_state());
 
   widget_->CloseNow();
 }
