nit: Seems like this should still need to be forward-declared, no?

+// Ths class exercises GoogleURLTracker.  In order to avoid instantiating more
+// of the Chrome infrastructure than necessary, the GoogleURLTracker functions
+// are carefully written so that many of the functions which take WebContents*,
+// NavigationController*, InfoBarTabHelper*, or objects containing such pointers
+// (e.g. NotificationSource) do not actually dereference the objects, merely use
+// them for comparisons and lookups, e.g. in an InfoBarMap.  This then allows
+// the test code here to not create any of these objects, and instead supply
+// "pointers" that are actually reinterpret_cast<>()ed magic numbers.  Then we
+// write the necessary stubs/hooks, here and in TestInfoBarDelegate above, to
+// make everything continue to work.
+//
+// Technically, the C++98 spec defines the result of casting
+// T* -> intptr_t -> T* to be an identity, but intptr_t -> T* -> intptr_t (what
+// we use here) is "implementation-defined".  Since I've never seen a compiler
+// break this, though, and the result would simply be a failing test rather than
+// a bug in Chrome, we'll use it anyway.
