Test Tool (OCTT)

Test Tool (OCTT)


OCTT is the Compliance Test tool for OCPP implementers to test their devices on protocol conformity. With this tool you can test your OCPP 2.0.1 and OCPP 1.6 implementation and check if you have implemented the OCPP specification correctly.

OCTT is our platform for testing OCPP implementations of a Charging Station Management System (CSMS), a Charging Station (CS) or a Charging Station Software Stack (CSSS). While the focus when developing OCTT has been to support OCPP version 2.0.1, this is being currently extended to support OCPP 1.6 and will support future OCPP versions as well.

OCTT is a cloud-based solution hosted by The Open Charge Alliance and is available as a subscription service with a sleek (web-based) interface to make it as easy as possible to test OCPP implementations for your organization’s internal use. The key features of OCTT are:

    • User-friendly web-based user interface to run OCPP conformance tests
    • Hosted solution with updates included, no need to worry about installations or upgrades
    • Extensive configuration options and functionality to define multiple configurations profiles
    • Online Testcase documentation with links to the included OCPP specification
    • Real-time detailed insight in the test case execution with clear error messages
    • Detailed logging and insight in the testcase execution and result (including all messages)

OCTT currently contains a set of test cases for the OCPP 2.0.1 Core and Advanced Security certification profiles and a subset of the test cases for the other OCPP certification profiles. We are still extending the coverage of OCTT with:

    • Additional testcases and coverage for the other OCPP 2.0.1 certification profiles (e.g. ISO15118)
    • APIs to automatically execute testcases for integration in CI/CD and test automation
    • Coverage for OCPP 1.6 (J)

OCPP Compliance Testing Tool can be used to test predefined testcases **) to test the conformance to the guidelines specified in the OCPP specification and includes  the documentation of these testcases. The tool can test the OCPP compliance of both a CS/CSSS and CSMS. When testing a CS/CSSS, OCTT will act as a CSMS and vice versa.

**) Please note that OCTT is capable of executing predefined scenario’s only, it is NOT a CS/CSSS or CSMS simulator.
