News / Did you know? OCTT and Golden SUTs

OCTT is the Compliance Test Tool for OCPP implementers to test their devices on protocol conformity.

It is continuously updated, due to maintenance, bug fixes, new features and new test cases. Every two months, a new OCTT version is released, that must be validated against a number of systems – or SUTs. To speed up and improve the release of new features and bugfixes, OCA is looking for OCPP enthusiasts to apply to become an ‘OCPP Golden SUT’! Everyone who has OCTT received an e-mail this week.

What does an OCPP Golden SUT do?

An ‘OCPP Golden SUT’ is an OCPP implementation of a Charging Station (Software Stack) or a CSMS that helps OCA to validate the OCTT and the OCPP test cases.
