COBOL Advanced Monitoring Features › Composite Module Testing

Composite Module Testing

Composite support lets you take of all CA InterTest functions when you test composite modules. A composite module consists of separately compiled modules link‑edited in one load module. These modules may be written in different languages and compiled at different times. Composite support lets you test and debug a called subroutine as if it were a separate program with full symbolic support.

Example

Suppose a COBOL program has several subroutines, some written in COBOL, some written in Assembler and PL/I. You can test and debug any of the subroutines just as if it were a main program by setting breakpoints, setting monitoring options, displaying the source listing, and displaying and modifying main and auxiliary storage.

Composite module monitoring is initiated by specifying the COMPOSITE command in the Source Listing Display screen before monitoring is activated (PF5) for the program.

When you specify the COMPOSITE command, CA InterTest displays the link‑edit information for the main program and its subroutines. You can change this information online, as shown in the following screen:
