+Feature: FlowMod
+  Scenario: new
+    When I create an OpenFlow message with:
+      """
+      Pio::PortMod.new(
+        port_no: 1,
+        mac_address: '11:22:33:44:55:66',
+        config: [],
+        mask: [:port_down],
+        advertised: []
+      )
+      """
+    Then the message has the following fields and values:
+      | field       | value             |
+      | port_no     | 1                 |

+  Scenario: read
+    When I parse a file named "open_flow10/port_mod.raw" with "PortMod" class
+    Then the packet has the following fields and values:
