jPOS Client Simulator: functional testing on the Control Plane
· 5 min read
Payment systems are only as trustworthy as the testing behind them.
For an issuer, correctness is not just a response code. It is the ISO 8583 message on the wire, the product rules that shaped the decision, the ledger entries that were posted, and the evidence an operator can inspect later.
The new Client Simulator demo shows that loop end to end on the jPOS Control Plane: a live jCard issuer, a real CMF channel, a functional test suite, raw logs, and a reconciled general ledger.
