OpenTP1 provides test support programs (testers) for checking UAP operation. OpenTP1 also provides a troubleshooting facility, the UAP trace facility, for troubleshooting UAP operation.

The OpenTP1 testers include online testers which operate in an online environment with TP1/Server Base or TP1/Message Control and an offline tester used in an offline environment.

The UAP trace facility can be used with TP1/Server Base.
