Testing a TP on MVS

The best way to test a TP on MVS is to:

Test a private copy of the TP under a TSO/E user ID, then
Test the TP under APPC/MVS scheduling (while restricting use of the TP to your own TSO/E user ID).

For these tests, you must create an environment called a test shell, which allows the TP to run in any address space as if it were running in an APPC/MVS initiator address space. You can also include interactive debugging facilities in the test shell to help test and diagnose the TP.

To create a test shell, you must call the APPC/MVS test services described in Descriptions of APPC/MVS Test Services. APPC/MVS provides three methods that you can use to invoke the test services, which are described in Methods You Can Use to Create a Test Shell.
