+
+Background: Example solution is deployed
+ Given a running example
+
+ Scenario: New row in source database is replicated to the destination
+ databasee
+ When A row is inserted in the source database
+ | id | first_name | last_name | email |
+ | 1 | John | Doe | john.doe@example.com |
+ Then a row is present in the destination database
+ | id | first_name | last_name | email |
+ | 1 | John | Doe | john.doe@example.com |
