+# collection task scheduled to run every second.

+# This test assumes current round-robin policy:
+# - default backend is rotated every time we successfully pick an upstream
+# - upstream connections within the same backend are rotated in the same way
+# - the monitor entry order for upstream connections reflects the connection
