9. Behaviour Driven Development
   Validating the Requirement
   Executable Acceptance Criteria for User Stories with a
   DSL modeled using the conceptual system model
   - Readable/Reusable
   Scenario: Submit trade for a valid instrument with set mandatory fields
   Given a registered user “CCP Admin” is available
   And an instrument “ABC100” is available
   And a trade is created with mandatory-trade-fields set to “mandatory-trade-values-A”
   And the trade is updated with instrument-id “ABC100”
   When the user submits the trade
   Then the processed trade is acknowledged as accepted
   And the processed trade has it’s fields user-set-fields available
