The SP 26 version of Process Integration Test comes with a great new feature for all those people, who ever regretted that it is not allowed to change an existing message exchange in the test dataset or who experienced the need to upload an own message exchange into PIT.
First of all, in order to clarify it – no, editing of message exchanges in test datasets is still no allowed. But with a new entity test data draft you can compile you own test datasets with custom message exchanges.
A test data draft contains one or more message exchange drafts. At first, you define the initial version of your message exchange draft creating it from scratch, or you take over an existing message exchange from a test dataset as template and modify it. In the next step, this message exchange is processed by the PI pipeline to get a complete and valid message exchange with incoming (Before Mapping) and outgoing (After Mapping) version. Once you are satisfied with the results, you can create a test dataset with this data, assign it to a test case and use in your test case run configurations.
