-// ui::test::EventGenerator is a tool that generates and dispatches events.

-//
-// This class is not suited for the following cases:
-//
-// 1) If your test depends on native events (ui::Event::native_event()).
-//   This return is empty/NULL event with EventGenerator.
-// 2) If your test involves nested message loop, such as
-//    menu or drag & drop. Because this class directly
-//    post an event to WindowEventDispatcher, this event will not be
-//    handled in the nested message loop.
-// 3) Similarly, |base::MessagePumpObserver| will not be invoked.
-// 4) Any other code that requires native message loops, such as
-//    tests for WindowTreeHostWin/WindowTreeHostX11.
-//
-// If one of these applies to your test, please use |ui_controls|
-// package instead.
-//
-// Note: The coordinates of the points in API is determined by the
-// EventGeneratorDelegate.
