-Feature: reset network stats with `trema reset_stats' command
+Feature: trema reset_stats command
 
-  As a Trema user
-  I want to reset network stats with `trema reset_stats' command
-  So that I can easily debug trema applications
+  In order to reset the stats of sent/received packets
+  As a developer using Trema
+  I want to execute "trema reset_stats" command
 
-  Scenario: trema help reset_stats
-    When I try to run "./trema help reset_stats"
-    Then the output should be:
+  Background:
+    Given a file named "learning_switch.conf" with:
       """
-      Usage: trema reset_stats [OPTIONS ...]
-          -h, --help
-          -v, --verbose
+      vswitch { datapath_id 0xabc }
+
+      vhost("host1") { ip "192.168.0.1" }
+      vhost("host2") { ip "192.168.0.2" }

+  @slow_process
+  Scenario: reset_stats host1
+    When I run `trema reset_stats host1`
