Cannot make tests with post request and file upload

Hi,

I’d like to make some stress test on my nodejs server with post requests that send files on the server. Here is the code I’m testing with:

config:
  target: 'https://websi.te'
  phases:
    - duration: 10
      arrivalRate: 10

scenarios:
  - flow:
    - get:
        url: "/"
    - post:
        url: "/upload/"
        formData: 
          photos: '@./file.jpg'
          token: 'myToken'

The error I have on my server is the following:

(node:27684) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 100): TypeError: Cannot read property 'token' of undefined

I have also an error 500 if I remove the token and its requirement from the server.

Note that this NodeJs Request code is working:

var options = { method: 'POST',
  url: 'http://websi.te/upload',
  headers: 
   { 'postman-token': '4997a0b0-71c8-61cf-c434-2b458dd4320c',
     'cache-control': 'no-cache',
     'content-type': 'multipart/form-data; boundary=----WebKitFormBoundary7MA4YWwktrZu0gW' },
  formData: 
   { photos: 
      { value: 'fs.createReadStream("file.jpg")',
        options: { filename: 'file.jpg', contentType: null } },
     token: 'myToken' } };

request(options, function (error, response, body) {
  if (error) throw new Error(error);
  console.log(body);
});

Thanks for your help.

I had the same problem and finally made it working. Here’s the example:

Config file:

config:
  target: 'http://localhost:8080'
  phases:
    - duration: 1
      arrivalRate: 1
  processor: './processor-utils.js'
scenarios:
  - flow:
    - post:
        url: '/upload/ocr'
        beforeRequest: 'setJSONBody'
        afterResponse: 'logResponse'
        formData:
          email: '[e-mail]'

processor-utils.js

const fs = require('fs');

module.exports = {
  setJSONBody,
  logResponse,
}

function setJSONBody(requestParams, context, ee, next) {
  const formData = {
    fileOCR: fs.createReadStream(__dirname + '/files/ocr.png'),
  };

  requestParams.formData = Object.assign({}, requestParams.formData, formData);

  return next();
}

function logResponse(requestParams, response, context, ee, next) {
  console.log('[DEBUG] Response: ', response.body);
  return next();
}

Can you point me to an example please? Thanks.
