Unit Test with Unsupported Media Type response in HapiJS

I'm doing the unit-testing with lab for a service in hapijs . The service basically asks for a file:

server.route({
  method: 'POST',
  path: '/file',
  config: {
    payload:{
      output:'stream',
      parse: true,
      allow: 'multipart/form-data'
    }
  },
  handler: function(request, reply){
    reply({ message: 'File saved' });
  }
});

Being your unit-test :

var request = {
  method: 'POST',
  url: '/file',
  payload: {
    file: {
      value: fs.createReadStream('input.csv')
    }
  }
};

lab.test('it return the default message to file index', (done) => {
  server.inject(request, (response) => {
    Code.expect(response.result.message).to.match(/File saved/);
    Code.expect(response.statusCode).to.equal(200);
    done();
  });
});

The fact is that when I run the unit testing returns { statusCode: 415, error: 'Unsupported Media Type' } . So I think I should indicate the content-type in headers but I'm not sure what values are needed and where they should go.

To add the headers to that request you can modify your request object like this:

var request = {
  method: 'POST',
  url: '/file',
  headers : {
        "Content-Type" : "..."
      },
  payload: {
    file: {
      value: fs.createReadStream('input.csv')
    }
  }
};

You can check the comments in this issue to see a user's example.

After researching I found the answer using form-data and stream-to-promise :

var FormData = require('form-data');
var streamToPromise = require('stream-to-promise');

lab.test('it return the default message to file index', (done) => {
  var form = new FormData();
  form.append('file', fs.createReadStream('input.csv'));

  streamToPromise(form).then((payload) => {
    var request = {
      method: 'POST',
      url: '/file',
      payload: payload,
      headers: form.getHeaders()
    };

    server.inject(request, (response) => {
      Code.expect(response.result.message).to.match(/File saved/);
      Code.expect(response.statusCode).to.equal(200);
      done();
    });
  });
});
