Maybe add a couple more tests, like the normal case (e.g. selects World at
position 6) and the case where nothing can be selected?  Or a TODO for this?

+{
+    RefPtrWillBeRawPtr<Text> text = document().createTextNode("Hello World!");
+    document().body()->appendChild(text);
+    selection().selectWordAroundPosition(VisiblePosition(Position(text, 5)));
+    EXPECT_EQ("Hello", WebString(selection().selectedText()).utf8());
 }
+
+}
