INQUIRY: upload multipart form file using external functions about tavern HOT 1 OPEN

If I understand the question correctly, I think this should work if you make your function return a dictionary with the file key like

def read_from_file(filename):
	return {
		"file": ...
	}

And use it in the test like

 files:
    file: "tests/acceptance/testdata/auto-written-file-upload.csv"
  data:
    $ext:
      function: testing_utils:read_from_file
      kwargs:
        filename: auto-written-file-upload.csv

Basically you can't have a $ext function anywhere except the top level of a 'data' json' etc. block

from tavern.
