Step 4: Testing the Application

If the mainframe transaction processing program is unchanged, it does not require testing. If the transaction processing program has been modified, then the COBOL program should be tested independently to ensure that it runs correctly in its own environment.

To test the new application

  1. Ensure that the COMTI component library is registered in Component Services.
  2. Test the mainframe transaction processing independently, if it has been modified in any way.
  3. Test the newly developed COMTI component independently to ensure that it is working correctly.
  4. Test the application, running the mainframe transaction processing program.
