How to test OData services in SAP NetWeaver Gateway is of great interest for our customers.
For testing OData services in SAP NetWeaver Gateway SAP has provided the SAP NetWeaver Gateway Client that can be started using transaction /IWFND/GW_CLIENT. The Gateway Client is a built in REST client that allows to store test cases and run one or more stored test cases in a sequential order. This way it is for example possible to test the CRUD methods of an OData service by creating an object, querying the object, updating the object and finially deleting it.
Customers have however requested that SAP would also offer support for performing tests using Extended Computer Aided Test Tool (eCATT) . eCATT is used by customers frequently to create and execute functional tests. Its primary aim is the automatic testing of SAP business processes. Each test generates a detailed log that documents the test process and results.
Though this functionality has not been added to the standard delivery of SAP NetWeaver Gateway our development team decided to publish the
Gateway Test APIs as aproject on Code Exchangein SCN so that it can be leveraged by our customers.
With the availability of Gateway Test APIs customer requests can be satisfied to enable eCATT based Test Automation for ODATA Services.
Any feedback to the functionality we posted is welcome 
.
Special thanks goes to my colleague Kranti Khilari for working hard on this.
Best Regards,
André
