The following APPC/MVS test services are used to create a test shell for a TP under test:

Register_Test

Places an inbound TP (the TP to be tested) in "test mode", and performs the setup required to start the TP in the caller's address space when inbound allocate requests arrive for the TP.

Accept_Test

Informs the APPC address space that the test shell is ready to accept inbound allocate requests for the TP, and suspends execution on the issuing address space.

Unregister_Test

Cancels an outstanding Register_Test request to prevent the TP from running under the test shell.

Cleanup_TP

Deallocates and cleans up any conversations and resources that are left after the test is complete. You must call this service if you plan to create another test session in the same TSO/E address space.
