Failure/Error: get :show, id: @user.id, format: :json

Question

I'm trying to test this controller but an error is returning.

class Api::V1::UsersController < ApplicationController
  respond_to :json

  def show
    respond_with User.find(params[:id])
  end

end

require 'rails_helper'

RSpec.describe Api::V1::UsersController, type: :controller do
  before(:each) { request.headers['Accept'] = "application/vnd.marketplace.v1" }

  describe "GET #show" do
    before(:each) do
      @user = FactoryBot.create :user
      get :show, :id => @user.id, format: :json
    end

    it "returns the information about a reporter on a hash" do
      user_response = JSON.parse(response.body, symbolize_names: true)
      expect(user_response[:email]).to eql @user.email
    end

    it { should respond_with 200 }
  end
end

bundle exec rspec spec/controllers/api/v1/users_controller_spec.rb

Controller specs are deprecated, FYI. You should switch to using request specs for new tests. — meagar♦

You should be passing a params hash containing the parameters you're interested in submitting:

get :show, params: { id: @user.id }

Failure/Error: get :show, id: @user.id, format: :json
