I'm not sure I understand this comment.  What are you trying to test?  That the
RLZ string caching works?

[Ivan Korotkov, 2012/12/14 15:32:44]

More likely that Init() has been called (otherwise this call would return
|false| as rlz value isn't in cache yet). I haven't come up with a better way to
test it with the given RLZTracker API.

+      RLZTracker::CHROME_HOME_PAGE, &rlz_string));
+  EXPECT_EQ(string16(), rlz_string);
