RSpec does not find my view helper

Question

I get this error when I run my test

spec/helpers/bikes_helper_spec.rb:3:in `<top (required)>':
uninitialized constant BikesHelper (NameError)

bikes_helper

require "spec_helper"

describe BikesHelper do

  describe "#km_until_next_service" do
    it 'returns a human readable number' do
      expect(km_until_next_service(1000)).to eq '1000 kilometers'
    end

  end
end

app/helpers/bikes_helper.rb

module BikesHelper

  include ActionView::Helpers::NumberHelper


  def km_until_next_service(km_untill_next)

    if km_untill_next == 0
      return "NOW"
    elsif (km_untill_next < 0)
      return "Overdue by #{number_to_human(km_untill_next, unit: :distance)}"
    elsif (km_untill_next > 0)
      return "In #{number_to_human(km_untill_next, unit: :distance)}"
    end

  end
end

Any idea why it does not recognise BikesHelper?

Answer 1

Try to

require 'rails_helper'

instead of

require 'spec_helper'
