How to write a remote request spec?

Question

I've got an action in my rails app that responds both in html and js format. The result, according to the format, changes a bit. So I'd like to write one test for html and other for js response. I'm using rspec.

Controller:

# app/controllers/my_controller.rb
class MyController < ApplicationController
  def my_action
    respond_to do |format|
      format.html do
        # Do something...
      end

      format.js do
        # Do something else...
      end
    end
  end
end

Spec:

# spec/requests/my_spec.rb
require "rails_helper"

RSpec.describe "My", type: :request do
  describe "GET /my_action" do
    context 'HTML' do
      # HTML tests
    end

    context 'JS' do
      # JS tests
    end
  end
end

Yes, that is how you do it. I don't understand what your question is. — Marlin Pierce, Mar 18 '20 at 21:32
The problem is that I don't know how to trigger a js request in rspec. — Chiara Ani, Mar 18 '20 at 21:34

Rails detects request format via http Accept header, in tests there's a helper for simulating xhr (also sets X-Requested-With, which is part of CSRF mitigation):

get "/some/path/to/my_action", xhr: true

You can try all the possible combinations of this:

put :update, params.merge(format: :js), xhr: true, format: :js, headers: { 'HTTP_ACCEPT' => 'text/javascript' }

and then remove one of the parameters to test to find the final one.
