Unit test file uplload

[PeterAshfordPEL]

Hi there!
I'm unit testing ariadne graphql mutations using calls to graphql_sync which is working really well. However I have one mutation that takes a file upload. I can test this from the command line using curl, but I'd like to be able to add a python unit test for the upload to our standard test suite.
My problem is that I don't know how to write a test that exercises the file upload. I've been Googling for answers with no success.

Here's test that does this for plain WSGI server, maybe this will help you somehow?

Hi everyone. Sorry for reviving this discussion, but I have a similar problem testing an application with starlette's test client. Here's what I'm trying to do

    # Upload profile pic
     update_query = """
       mutation UploadAvatar($image: Upload!, $id: Int!) {
          uploadUserImage(image: $image, id: $id) {
            id
            ok
          }
     }
     """
     files_map = {"0": ["variables.image"]}
     upload_data = {
        "operationName": "UploadAvatar",
        "query": update_query.replace('\n', '').strip(),
        "variables": {
          "image": None,
          "id": 1
        },
        "map": files_map
      }

      file_cont = get_sample_file_contents()
      files = {"file": (file_cont['name'], file_cont['content'], "image/png")}
      headers = {
        'content-type': 'application/json',
        'access_token': access_token
      }
      upload_resp = client.post("/api/graphql", data=json.dumps(upload_data), headers=headers, files=files)

I'm getting the following error

Variable '$image' of non-null type 'Upload!' must not be null.

It seems like I can't starlette's test client to correctly send the files mapping. Is there a way to do this with starlette's test client?
