+Feature: Can the adapter receive messages?
+  The adapter poll method works as expected
+
+  Scenario: No messages are received succecssfully if the queue is empty
+    Given valid config
+    When the adapter instance is created
+    When the auth method is called
+    When the queue contains 0 messages
+    When the poll method is called
+    Then a successful response is returned with 0 messages  
+
+  Scenario: 2 messages are received succecssfully if the queue contains 2 messages
+    Given valid config
+    When the adapter instance is created
+    When the auth method is called
+    When the queue contains 2 messages 
+    When the poll method is called
+    Then a successful response is returned with 2 messages
+
+  Scenario: 10 messages are received succecssfully if the queue contains 10 messages
+    Given valid config
+    When the adapter instance is created
+    When the auth method is called
+    When the queue contains 10 messages 
+    When the poll method is called
+    Then a successful response is returned with 10 messages
