// GoogleURLTrackerTest -------------------------------------------------------

// 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
// NavigationController* or InfoBarService* do not actually dereference the
// objects, merely use them for comparisons and lookups, e.g. in |entry_map_|.
// 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.
