A lot of people have been asking how to use the collection runner to run collections which have requests with file-uploads. Right now, it’s not possible to upload files in the collection runner. However, you can use Newman, Postman’s command-line companion, as a workaround:
- Create a collection in Postman. Check out a sample collection here https://www.postman.com/collections/7b09e5e27f6d1773d965. This collection sends a single POST request, with two form parameters – one file param, and one text param. The file that was used is https://gist.github.com/abhijitkane/4aba1c3deeb4ed61a623
The request runs successfully in the main Postman window:
- Export the file as a JSON, and save it to your filesystem.
Open the JSON file for editing. In line 22, change the “value” property of the file param to the complete path of the file:
- Run the collection file in Newman:
If you are using Windows, be sure to change the backslashes () in the JSON file to double-backslashes so that the JSON remains valid, e.g. if your “value” is “C:\Documents\collection.json”, you’ll need to change it to “C:\\Documents\\collection.json”.
