I looked around and can't figure this error out.

While running a spec I get this error right where the binding pry is Errno::ECONNREFUSED: Failed to open TCP connection to localhost:3000. Any ideas on how to fix it?

When I run the development rails server the error goes away and the code runs.

    10: def call

 => 11:   binding.pry

    12:   image = MiniMagick::Image.open(url)

    13: end



[1] pry(#<ResizeImage>)> image = MiniMagick::Image.open(url)

Errno::ECONNREFUSED: Failed to open TCP connection to localhost:3000 (Connection refused - connect(2) for "localhost" port 3000)

from /Users/josephkonop/.rvm/rubies/ruby-2.5.1/lib/ruby/2.5.0/net/http.rb:939:in `rescue in block in connect'

Here is the code

class ResizeImage

  attr_reader :url, :width, :height



  def initialize(params)

    @url = params[:url]

    @width = params[:width]

    @height = params[:height]

  end



  def call

    binding.pry

    image = MiniMagick::Image.open(url)

  end

end



The spec:



RSpec.describe 'Image Resizer', type: :request do

  describe '#create' do

    context 'when valid params' do

      let(:image_url) { ActionController::Base.helpers.asset_path("cat.jpg") }

      let(:width) { 300 }

      let(:height) { 200 }



      before do

        post "/api/v1/resize?url=#{image_url}&width=#{width}&height=#{height}"

      end



      it 'response' do

        expect(response.body).to eq('')

      end

    end

  end

end



Test.rb



config.action_controller.asset_host = 'http://localhost:3000'
