I have an email helper extension I have written for my application. I use settings I have defined on the application like so:
set :mailgun_options, JSON.parse(File.open('config/mailer.json').read)[ENV['RACK_ENV']]
which reads configuration settings from a json file into the global Sinatra settings.
I then have my email helper which references these settings to create connections and what not.
require 'sinatra/base'
require 'faraday'
module Sinatra
module EmailHelper
def connect opts={}
connection = Faraday.new(:url => settings.mailgun_options['mailgun_url']) do |faraday|
if settings.mailgun_options['test']
faraday.adapter :test do |stubs|
stubs.post(settings.mailgun_options['domain'] + '/messages') {[ 200, {}, 'success' ]}
end
else
faraday.request :url_encoded
faraday.adapter Faraday.default_adapter
end
end
connection.basic_auth('api', settings.mailgun_options['key'])
return connection
end
def send_email params={}
connect.post((settings.mailgun_options['domain'] + '/messages'), params)
end
def send_password_reset_email email
template = File.open( File.expand_path( '../../helpers/email_helper/templates/password_reset.erb', __FILE__ ), 'r' ).read
send_email({
:from => 'REscour <noreply@' + settings.mailgun_options['domain'] + '>',
:to => email,
:subject => 'REscour.com Password Reset',
:text => ERB.new(template).result(binding)
})
end
end
end
So, when I am trying to write my specs to test the "connect" method, I get the following error:
undefined local variable or method `settings' for #<Class:0x007faaf9c9bd18>
My spec code is as follows:
module Sinatra
describe EmailHelper
let(:dummy_class) { Class.new { extend EmailHelper } }
it 'should connect to mailgun\'s api' do
app.set :mailgun_options, ::JSON.parse(File.open('config/mailer.json').read)['test']
puts dummy_class.connect
end
end
end
I'm not sure how to interact with the global Sinatra settings from my specs to have the local "settings" variable be defined during execution of the helper code.
I could have the architecture of my application wrong here for all I know. Does anyone have any experience in writing Sinatra extensions using the global settings and write specs for them?
