Program test vehicle (PTV) is an online utility (referred to as the PTV utility in the remainder of this book) that enables you to test application programs in progressive levels of system involvement. Applications are tested individually, with related programs, within a transaction, and within a full TPF system.
There are 3 distinct test activities:
A test unit is defined by you. User-defined input is recorded on the test unit tape by the system test compiler (STC).
You provide control record information that defines each test unit. These records specify:
An operational system includes the system segments, application programs, and data stored on disk packs called online modules. These are created by the system loader. See the TPF System Installation Support Reference for more information about the system loader.
During this phase, the PTV utility performs tests and provides information required to verify program reliability.
Data from the test run is written to the real-time log tape. PTV output is formatted and printed by the offline diagnostic output formatter (DOF).
