+Description
+
+This test validates the values in resource timing for a timing allowed cross-origin redirect.
+
+
+
+PASS Starting document.location.hostname is correct (127.0.0.1:8000) 
+PASS redirectStart should be greater than 0 in timing allowed cross-origin redirect! 
+PASS redirectStart should be equal to startTime in timing allowed cross-origin redirect! 
+PASS redirectEnd should be no less than redirectStart in timing allowed cross-origin redirect! 
+PASS fetchStart should be no less than redirectEnd in timing allowed cross-origin redirect!
