Question

I saw various versions of how to setup a global HTTP_REFERER in RSpec, but none of them worked with RSpec 2.6.4:

RSpec.configure do |config|
  config.before(:each, :type => :controller) do
    request.env["HTTP_REFERER"] = root_url
  end
end

The request is always nil:

undefined method `env' for nil:NilClass

RSpec is calling this:

def self.eval_before_eachs(example)
  world.run_hook_filtered(:before, :each, self, example.example_group_instance, example)
  ancestors.reverse.each { |ancestor| ancestor.run_hook(:before, :each, example.example_group_instance) }
end

Answer 1

# spec/support/http_referer.rb  
module HttpReferer
  def self.included(base)
    base.class_eval do
      setup :setup_http_referer if respond_to?(:setup)
    end
  end

  def setup_http_referer
    @request.env["HTTP_REFERER"] = "/back"
  end
end

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