Storing the message payloads is a prerequisite in order to create test cases, re-run them and then validate the execution. Our solution requires the message payloads to be send to Int4 IFTT WebService, together with the additional interface details.
Another important aspect is that you should be able to choose when the payloads are saved in Int4 IFTT, for that purpose, depending on the middleware, a proper trace indicator should be available to set the persistence on and off.
In Int4 IFTT the message payload are stored in a database table with all the additional interface details.
