+Feature: Testing a REST API
+  Users should be able to submit GET and POST requests to a web service, represented by WireMock
+
+  Scenario: Data Upload to a web service
+    When users upload data on a project
+    Then the server should handle it and return a success status
+
+  Scenario: Data retrieval from a web service
+    When users want to get information on the Cucumber project
+    Then the requested data is returned
