// This is a convenience base class for all tests to provide some
// common functionality.  It sets up a MenuButton and a MenuItemView
// and clicks the MenuButton.
//
// Subclasses should implement:
//  BuildMenu()            populate the menu
//  DoTestOnMessageLoop()  initiate the test
//
// Subclasses can call:
//  Click()       to post a mouse click on a View
//
// Although it should be possible to post a menu multiple times,
// MenuItemView prevents repeated activation of a menu by clicks too
// close in time.
