Executing a JavaScript utility before running a collection in Postman: Step-by-step guide

Regarding my needs Before executing the Postman Collection, I need to complete a few preliminary steps:

  • I need to use a JavaScript utility to generate JSON file containing input BODY data
  • The generated JSON file will then be used by another utility to create an expected JSON file
  • I am open to suggestions on how to incorporate the JSON file in the BODY of a POST request

I am seeking a solution for calling my JavaScript utilities every time before running the collection

This process will ensure that my POSTMAN tests run smoothly and eliminate any data dependencies

Any feedback or ideas on this approach are also appreciated
