How to upload file to API test

I use playwright to write API integration tests. I need call an API that uploads the file.

In the project I have a static assets folder:

/static-assets
   - import.xlsx

How do I reference the file so that I can make the API call?

import { request } from '@playwright/test';
const context= request.newContext();
await context.fetch(url, {
  method: 'POST',
  data: ??
});
Solution

  • playwright allows to read from filesystem so you can use readFileSync from from 'fs';

    import { readFileSync } from 'fs';
import { basename } from 'path';

const filePath = 'static-assets/import.xlsx'; //either full path or relative to project dir
const fileName = basename(filePath);
const file = new File([readFileSync(filePath)], fileName);

//in my case I needed multipart form data
const form = new FormData();
form.append('SomeOtherField', 'BlaBla') ;
form.append("File", file);

context.fetch(url, {
  method: 'POST',
  multipart: form,
});
