We have been getting request on using Figaf IRT as a way to improve the testing of existing customers existing testing application. This will allow you to test both SAP PI/PO and SAP Cloud Platform Integration (CPI) in the flows.
A few releases ago we released the new testing principle for Baseline testing. Baseline testing requires that you are sending the same messages into the system again, as the perfect companion to when you have existing test scripts in Solman or in this case HPE UFT. If you want to integrate with any tool then this guide provides a good way to start the integration.
In your existing HPE UFT, ALM or Worksoft solution can create a comparison and do validation of which messages are sent. There is an API to read the messages from the PI system, it would tough require a lot of coding to ensure that you got all the validations correct. We are really good a making test of the messages in an Integration system, so you can just focus on creating the validations of existing programs. It would be really beneficial for you to know what messages are changed and why.
The steps in the procedure are outlined in the video below. It will probably take you 10-15 minutes to add the IRT component to each script that you are running. You need to run the script a few times to ensure that it works and you have configured IRT correct. The video covers how to set this up.
