Run multiple images/files with iteration data variable using Postman Runner or Newman

Question

Scenario

I have a POST request API which accepts Image or File. As shown below:

I can select an image from the Request body as a form-data but, here I can select one image at a time.

But I want to upload multiple images or files as a form-data variable like {{image}} or {{file}} while doing Postman-Collection Runner. As we know, we can only upload text/JSON/CSV file as iteration data in Postman Runner.

Questions: Is there any way from which we can send multiple images or files as Iteration data in Postman Runner or in Newman?

or

Can I have a Postman test script that will upload multiple images or files in Postman Runner?

Or else

Help me in how to upload multiple images using Newman.

Can anyone please help me with this?

Answer 1

I had the same issue and solve it without newman.

I exported my collection in json and set "src": "{{value}}" in the body of exported .json file:

"body": {
                    "mode": "formdata",
                    "formdata": [
                        {
                            "key": "file",
                            "type": "file",
                            "src": "{{value}}"
                        }
                    ]
                }

After that I added new json file with different files for value:

[{
  "path": "post",
  "value": "1.png"
}, {
  "path": "post",
  "value": "2.png"
}, {
  "path": "post",
  "value": "3.png"
}, {
  "path": "post",
  "value": "4.png"
}]

Be sure that these files exists in working directory of postman (it can be set in settings)

After that I imported these collection back into postman. The form-data of the request is: enter image description here

When we run the collection we choose in data the json file with values. enter image description here

The result was that my request executes 4 times and every time it uploads different file.

What you can possibly do is , create those many test cases in your iteration data file. for example if you want to upload 10 images so you can create 10 testcases in your test data file and run it as a part of collection runner
