Do you want to extract this whole method into InspectorTest.logCallChain() ?

Done.

   var asyncStackTrace = message.params.asyncStackTrace;
   while (asyncStackTrace) {
-    InspectorTest.log(`-- ${asyncStackTrace.description} --`);
+    if (asyncStackTrace.promiseCreationFrame) {
+      var frame = asyncStackTrace.promiseCreationFrame;
+      InspectorTest.log(`-- ${asyncStackTrace.description} (${frame.url
+                        }:${frame.lineNumber}:${frame.columnNumber})--`);
+    } else {
+      InspectorTest.log(`-- ${asyncStackTrace.description} --`);
+    }
     InspectorTest.logCallFrames(asyncStackTrace.callFrames);
     asyncStackTrace = asyncStackTrace.parent;
   }
