I align the `=`, so:

```ruby
it 'will support Cross Origin Resource Sharing' do
  ENV['RACK_CORS']           = 'enabled'
  ENV['RACK_CORS_ORIGINS']   = 'http://utensils.io/'
  headers['HTTP_ORIGIN']     = 'http://utensils.io/'
  headers['HTTP_USER_AGENT'] = 'Rspec'
  post '/barcodes', barcode_request, headers
  expect(last_response.headers['Access-Control-Allow-Origin']).to eq 'http://utensils.io/'
end
```
