+Feature: Pio::NiciraSendOutPort
+
+  Scenario: new(:reg0)
+    When I try to create an OpenFlow action with:
+      """
+      Pio::NiciraSendOutPort.new(:reg0)
+      """
+    Then it should finish successfully
+    And the action has the following fields and values:
+      | field                  |  value |
+      | action_type.to_hex     | 0xffff |
+      | action_length          |     24 |
+      | experimenter_id.to_hex | 0x2320 |
+      | experimenter_type      |     15 |
+      | offset                 |      0 |
+      | source                 |  :reg0 |
+      | max_length             |      0 |
