+This is a testharness.js-based test.
+Harness Error. harness_status.status = 1 , harness_status.message = 1 duplicate test name: "Measure of current mark to navigationStart should be negative value."
+PASS Measure of navigationStart to now should be positive value. 
+PASS Measure of navigationStart to loadEventEnd should be positive value. 
+PASS Measure of current mark to navigationStart should be negative value. 
+PASS loadTime plus loadEventEnd to a mark "a" should equal to navigationStart to "a". 
+PASS Measure of current mark to navigationStart should be negative value. 
+PASS Measures of loadTime should have same duration. 
+PASS Measure from domComplete event to most recent mark "a" should have longer duration. 
+PASS Measure from most recent mark to navigationStart should have longer duration.
