BDD Scenario
Scenario: Payment amount exceeds ACH limit
-
Given customer initiates ACH payment
-
And amount > configured ACH threshold (e.g. $100,000)
-
When payment is validated
-
Then system auto-flags payment for Wire upgrade
-
And ACH instruction is not sent downstream
-
And Wire instruction is created
Scenario: ACH message converted to Wire format
-
Given original ACH payment details
-
When upgrade occurs
-
Then Wire message (Fedwire / SWIFT MT/MX) is created
-
And beneficiary details remain unchanged
-
And payment reference is preserved
-
And original ACH trace ID is linked for audit
Scenario: Wire submission failure
-
Given ACH upgraded to Wire
-
When Wire fails (network / validation error)
-
Then:
-
Payment is not re-sent as ACH automatically
-
Customer is notified
-
Funds are held or reversed per policy
-
-
And exception workflow is triggered
Scenario: Regulatory and Compliance Scenario
-
Given payment is upgraded
-
When audit report is generated ay the maker and checker
-
Then report shows:
-
Original ACH request
-
Upgrade decision reason
-
Wire reference number
-
Timestamp & user/system ID
-
-
And complies with SOX / FFIEC requirements
Scenario: End-to-end tracking continuity for tracking the status
-
Given payment upgraded after cut off time
-
When status updates are generated
-
Then:
-
Original ACH status marked as “Upgraded to Wire”
-
Wire status progresses (Initiated → Sent → Pending → Settled/ Completed)
-
-
And customer can track payment in real time
