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. Test the mainframe transaction processing program independently, if it has been modified in any way.
  2. Test the newly developed COMTI component independently to ensure that it is working correctly.
  3. Test the application completely, by driving the COMTI object with the client application and running the mainframe transaction processing program.
  4. Carry out a transaction test. To do this, test the COMTI object with the transactions made available. Check operation between COMTI and Component Services, in conjunction with COMTI and the transaction processing program running on CICS.
