+Feature: CAMARA Call Fowarwing Signal  API, v0.1.0 - Operation unconditional-call-forwarding
+  # Input to be provided by the implementation to the tester
+  #
+  # Implementation indications:
+  #
+  # Testing assets:
+  # * A device object identified by a phone number for which unconditionnal call forwarding status could be retrieved
+  # * A device object identified by a phone number for which unconditionnal call forwarding status could not be retrieved (unknown)
+  #
+  # References to OAS spec schemas refer to schemas specifies in Call_Forwarding_Signal.yaml, version 0.1
+  Background: Common call-forwarding-signal setup
+    Given the resource "/call-forwarding-signal/v0/unconditional-call-forwardings"
+    And the header "Content-Type" is set to "application/json"
+    And the header "Authorization" is set to a valid access token
+    And the header "x-correlator" is set to a UUID value
+    And the request body is set by default to a request body compliant with the schema
+
+  # Happy path scenarios
+
+  # This first scenario serves as a minimum
+  @call_forwarding_signal_01_generic_success_scenario
+  Scenario: Common validations for any success scenario
+    # Valid testing device and default request body compliant with the schema
+    Given the request body property "$.phoneNumber" is set to a valid testing device supported by the service
+    And the request body is set to a valid request body
+    When the HTTP "POST" request is sent
+    Then the response status code is 200
+    And the response header "Content-Type" is "application/json"
+    And the response header "x-correlator" has same value as the request header "x-correlator"
+    # The response has to comply with the generic response schema which is part of the spec
+    And the response body complies with the OAS schema at "/components/schemas/UnconditionalCallForwardingSignal"
+
+  # Scenarios testing specific situations for the call forwarding signal
+  @call_forwarding_signal_02_unconditional_call_forwarding_check
+  Scenario: retrieve call forwarding signal on a device
+    Given the request body property "$.phoneNumber" is set to a valid testing device for which unconditionnal call forwarding status could be retrieved
+    And the request body is set to a valid request body
+    When the HTTP "POST" request is sent
+    Then the response status code is 200
+    And the response header "Content-Type" is "application/json"
+    And the response header "x-correlator" has same value as the request header "x-correlator"
+    And the response body property "$.active" is one of: ["true", "false"]
+
+  # Error scenarios for phoneNumber
+  @call_forwarding_signal_03_unconditional_call_forwarding_for_unknown_phone_number
+  Scenario: retrieve call forwarding signal on an unknown device
+    Given the request body property "$.phoneNumber" is set to a valid testing device for which unconditionnal call forwarding status could not be retrieved
+    And the request body is set to a valid request body
+    When the HTTP "POST" request is sent
+    Then the response status code is 404
+    And the response property "$.code" is "CALL_FORWARDING.UNKNOWN_PHONE_NUMBER"
+    And the response property "$.message" contains a user friendly text
+
+
+  # Generic 400 error
+
+  @call_forwarding_signal_400.1_no_request_body
+  Scenario: Missing request body
+    Given the request body is not included
+    When the HTTP "POST" request is sent
+    Then the response status code is 400
+    And the response property "$.status" is 400
+    And the response property "$.code" is "INVALID_ARGUMENT"
+    And the response property "$.message" contains a user friendly text
+
+  @call_forwarding_signal_400.2_empty_request_body
+  Scenario: Empty object as request body
+    Given the request body is set to "{}"
+    When the HTTP "POST" request is sent
+    Then the response status code is 400
+    And the response property "$.status" is 400
+    And the response property "$.code" is "INVALID_ARGUMENT"
+    And the response property "$.message" contains a user friendly text
+
+    # Generic 401 Error
