title: How to use postman to fully automate uploading a file to an endpoint
body: <p>We are trying to test uploading a file to an endpoint using automation, hoping we can use postman to test.</p>
  <p>But we are finding that we may not be able to fully automate it. The Amazon s3 endpoint we want to test only accepts real files, not urls. Postman seems to rely on already having the file for upload downloaded on the users system.</p>
  <p>Is there a way we can ensure when another dev goes into our workspaces in postman or tries to run our collection via newman, they don't have to manually download a dependency (file for upload) of the test first, instead letting the tests handle downloading their own dependencies?</p>
