Introduction
Int4 IFTT has a unique feature to provide service virtualization on an integration platform level.
...
Int4 IFTT Virtualization Component (VC) solves this inconvenience. It enables efficient manual testing of SAP S/4HANA while connected apps are virtualized and simulated.
How does it work?
The Service Virtualization process is possible with minimal investment using current hardware and installed Int4 IFTT. In addition, the Int4 IFTT Virtualization Component does not require changing the endpoints to original systems for asynchronous scenarios compared to the classical service virtualization tools.
...
The Int4 IFTT VC can dynamically deactivate the communication channels to virtualized applications in the SAP Process Orchestration platform. Moreover, Int4 IFTT VC will cancel the request message so that the original connected system will be unaffected.
How to set it up?
Setting up the service virtualization is pretty straightforward. The most crucial step is a replication of the behavior of the simulated system.
...
Identification of the interfaces to and from the external system
Specification of the transformation logic. You need to know what response is expected based on a particular request. It should be as dynamic as possible.
Manual testers should test different business scenarios, and the virtualization should simulate the actual behavior of the connected app. The response in each case is based on a request message (for example, material numbers or quantities), but the tester can also provide instructions. For this purpose, you can use control fields in the request document/message, like header text.
Implementation of virtualization logic in XSLT or middleware mapping.
Creation of Int4 IFTT automation objects
Activate the scenario by scheduling a virtualization job using the sequence of the test cases.
How to use it?
After customizing and configuration, the service virtualization is ready. Then, testers can execute manual testing. Whenever the business process requires calling an external app by application interface, Int4 IFTT VC will immediately capture the request and generate back the response to SAP S/4HANA. Thus, users can continue testing the process up to its end.
