RSpec Request - How to set http authorization header for all requests

Question

I\'m using rspec request to test a JSON API that requires an api-key in the header of each request.

I know I can do this:

get \"/v1/users/janedoe.json\"

To set it in a before hook you need to access it like

config.before(:each) do
  controller.request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Token.encode_credentials('mytoken')
end

I too hated the giant hash, but preferred to be explicit in authorizing the user in different steps. After all, it's a pretty critical portion, and . So my solution was:

#spec/helpers/controller_spec_helpers.rb
module ControllerSpecHelpers
  def authenticate user
    token = Token.where(user_id: user.id).first || Factory.create(:token, user_id: user.id)
    request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Token.encode_credentials(token.hex)
  end
end

#spec/spec_helper.rb
RSpec.configure do |config|
  ...
  config.include ControllerSpecHelpers, :type => :controller

then I can use it like so

describe Api::V1::Users, type: :controller do
  it 'retrieves the user' do
    user = create :user, name: "Jane Doe"
    authorize user
    get '/v1/users/janedoe.json'
  end
end

I find this great for testing different authorization levels. Alternatively, you could have the helper method spec out the authorize function and get the same result, like so

#spec/helpers/controller_spec_helpers.rb
module ControllerSpecHelpers
  def authenticate
    controller.stub(:authenticate! => true)
  end
end

However, for ultimate speed and control, you can combine them

#spec/helpers/controller_spec_helpers.rb
module ControllerSpecHelpers
  def authenticate user = nil
    if user
      token = Token.where(user_id: user.id).first || Factory.create(:token, user_id: user.id)
      request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Token.encode_credentials(token.hex)
    else
      controller.stub(:authenticate! => true)
    end
  end
end

and then authorize entire blocks with

#spec/spec_helper.rb
...
RSpec.configure do |config|
  ...
  config.before(:each, auth: :skip) { authenticate }

#**/*_spec.rb
describe Api::V1::Users, type: :controller do
  context 'authorized', auth: :skip do
    ...
