There is a standard Gateway client tool ( transaction code /IWFND/GW_CLIENT ) which allows us to launch odata request without browser for testing purpose. And there is another approach which can achieve the same result without using SAPGUI, that is Chrome extension: postman.
For example, we are doing some test in Fiori application and we observe the following batch operation in Chrome network tab. We would like to do unit or performance testing on it with the help of postman.
How to create the batch operation in postman
Just copy the value you find in Chrome network tab from screenshot above to the postman based on the number.
now the request header part is done. We continue to copy all the text in request payload into clipboard. ( select all, ctrl + C )
Choose “raw” tab, then Ctrl + V all the payload text into the text area, and then click Send button. Unfortunately we get 403 error, due to the missing CSRF token.
How to get CSRF token
Just create another http request in postman, request method sets to GET, and http header x-csrf-token with value Fetch, send the request, and the token is available in response header.
Once done, paste this token into our previous batch request as http header value:
And send the batch request once again, this time it works:
