Im currently writing my test cases using ruby sinatra and im having a very weird or just im missing an important note/tip when writing a test cases using Test-Unit sinatra.
My problem is my my environments.rb is not being loaded in my test from my app.rb. but if i run it, it does get loaded.
here is my app.rb
require 'rubygems'
require 'sinatra'
require 'pg'
require './config/environments'
require './models/user'
module Registration
class HelloWorldApp < Sinatra::Base
helpers do
include Rack::Utils
alias_method :h, :escape_html
end
get '/' do
#title = " Introduction Biatch"
erb :index
end
post '/register' do
DB[:users].insert(username: params[:username],password: params[:password])
redirect '/view'
end
get '/view' do
#users = User.all
erb :view
end
get '/view/:id' do
#user = User.find(id: params[:id])
erb :edit
end
post '/edit/:id' do
#user = User.find(id: params[:id])
#user.update(username: params[:username],password: params[:password])
redirect '/view'
end
get '/delete/:id' do
#delete_user = User.find(id: params[:id])
#delete_user.delete
redirect '/view'
end
end
end
my environments.rb is in the config folder.
and here is my sample test cases. (not yet finished)
require 'rubygems'
require 'test/unit'
require 'test/unit/assertions'
require '../app/app'
module Registration
class TestCrud < Test::Unit::TestCase
# include Registration::HelloWorldApp
def test_insert_user
end
def test_get_all_user
end
def test_delete_all_user
end
end
end
and this is the error it throws.

Im very confused what did i do wrong. thanks in advance.
Ive found the answer, just change the require './config/environments' to require_relative. and change the require '../app/app' into require_into.

So I am simply trying to run this code below with sunlight congress gem, but I seem to be doing something wrong. I am trying to include the gem in the project however something is off.
I am trying to implement this using RubyMine 7.1.2(if version matters), Ruby 2.2.2.
sunlight congress can be found here: https://github.com/sunlightlabs/ruby-sunlight.
Also, I am working on windows 8.1.
require 'csv'
require 'sunlight-congress'
require 'erb'
Sunlight::Congress.api_key = "e179a6973728c4dd3fb1204283aaccb5"
def neat_zip(zipcode)
zipcode.to_s.rjust(5,"0")[0..4]
end
def legislator_by_zip(zipcode)
Sunlight::Congress::Legislator.by_zipcode(zipcode)
end
def save_thank_you_letters(id,form_letter)
Dir.mkdir("output") unless Dir.exists?("output")
filename = "output/thanks_#{id}.html"
File.open(filename,'w') do |file|
file.puts form_letter
end
end
puts "EventManager initialized."
contents = CSV.open 'event_attendees.csv', headers: true, header_converters: :symbol
template_letter = File.read "form_letter.erb"
erb_template = ERB.new template_letter
contents.each do |row|
id = row[0]
name = row[:first_name]
zipcode = neat_zip(row[:zipcode])
legislators = legislator_by_zip(zipcode)
form_letter = erb_template.result(binding)
save_thank_you_letters(id,form_letter)
end
I am getting this error:
C:\Ruby22\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/Ruby22/event_manager/sunlight-congress-master/lib/event_manager.rb

from C:/Ruby22/event_manager/sunlight-congress-master/lib/event_manager.rb:2:in `<top (required)>'
from -e:1:in `load'

Do i simply have the path wrong? gem isnt installed?
You need to gem install sunlight-congress.

This is my first attempt with Sinatra. I built a simple classic app, set up RSpec for it, and got it working. Then, I tried to go modular, in a MVC fashion. Even though the app works in the browser, RSpec throws a NoMethodError. I've read Sinatra docs regarding RSpec, also searched a lot here in SO, but I can't find where the bug is. Any clue?
Thank you very much in advance.
Here are my relevant files:
config.ru
require 'sinatra/base'
Dir.glob('./{app/controllers}/*.rb') { |file| require file }
map('/') { run ApplicationController }
app.rb
require 'sinatra/base'
class ZerifApp < Sinatra::Base
# Only start the server if this file has been
# executed directly
run! if __FILE__ == $0
end
app/controllers/application_controller.rb
class ApplicationController < Sinatra::Base
set :views, File.expand_path('../../views', __FILE__)
set :public_dir, File.expand_path('../../../public', __FILE__)
get '/' do
erb :index
end
end
spec/spec_helper.rb
require 'rack/test'
# Also tried this
# Rack::Builder.parse_file(File.expand_path('../../config.ru', __FILE__))
require File.expand_path '../../app.rb', __FILE__
ENV['RACK_ENV'] = 'test'
module RSpecMixin
include Rack::Test::Methods
def app() described_class end
end
RSpec.configure { |c| c.include RSpecMixin }
spec/app_spec.rb
require File.expand_path '../spec_helper.rb', __FILE__
describe "My Sinatra Application" do
it "should allow accessing the home page" do
get '/'
expect(last_response).to be_ok
end
end
The error
My Sinatra Application should allow accessing the home page
Failure/Error: get '/'
NoMethodError:
undefined method `call' for nil:NilClass
# ./spec/app_spec.rb:5:in `block (2 levels) in <top (required)>'
I'm guessing you're following this recipe, correct?
The described_class in this line:
def app() described_class end
is meant to be the class under test, in this case ZerifApp. Try it like so:
def app() ZerifApp end
EDIT
It turns out the above answer is not correct about what described_class does. I assumed it was a placeholder -- actually it is an RSpec method that returns the class of the implicit subject, that is to say, the thing being tested.
The recipe at the link is misleading because of the way it recommends writing the describe block:
describe "My Sinatra Application" do
This is valid RSpec, but it does not define the subject class. Executing described_class in an example for this block will return nil. To make it work, replace the describe block:
describe ZerifApp do
Now described_class will return the expected value (ZerifApp)

It has some source code to get some ideas from.
This has code example too. https://github.com/laser/sinatra-best-practices
I'm considering using IronWorker a project so that I can scale it easily (high traffic expected, with lots of background jobs).
In order to stay DRY, I'm trying to define workers using inheritance but I keep getting the following error:
/usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- base_worker.rb (LoadError)
from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from /task/child_worker.rb:3:in `<top (required)>'
from /task/runner.rb:344:in `require_relative'
from /task/runner.rb:344:in `<main>'
Here is the base worker class:
# app/workers/base_worker.rb
require 'net/http'
require 'uri'
require 'json'
class BaseWorker < IronWorker::Base
attr_accessor :params
# The run method is what IronWorker calls to run your worker
def run
data = custom_run(params)
common_post_process(data)
end
def custom_run(params)
#to be overwritten in the child class
end
def common_post_process(data)
# some common post processing => DRY
....
end
end
And here is a child class :
# app/workers/child_worker.rb
require 'net/http'
require 'uri'
require 'base_worker.rb'
class ChildWorker < BaseWorker
merge "base_worker.rb"
def custom_run(params)
#custom work
end
end
Any idea on how to fix this?
I'd recommend using our next generation gem, iron_worker_ng: https://github.com/iron-io/iron_worker_ruby_ng . The iron_worker gem is deprecated. And if you want to keep it similar style to what you have, your child_worker.rb might look like this:
require 'net/http'
require 'uri'
require_relative 'base_worker.rb'
class ChildWorker < BaseWorker
def custom_run(params)
#custom work
end
end
# NG gem doesn't run anything in particular, so to run your method:
cw = ChildWorker.new
cw.custom_run(params)
And in a child_worker.worker file:
runtime 'ruby'
file 'base_worker.rb'
exec 'child_worker.rb'
Then to upload it to IronWorker:
iron_worker upload child_worker
Then you can start queuing jobs for it:
worker = IronWorkerNG::Client.new
worker.tasks.create("child_worker", params)
If you use iron_worker_ng, it also possible to define a run method. This method will be called when the IronWorker runs. You have to specify the Class within the .worker file.
# child_worker.rb
class ChildWorker
def run
puts "doing the hard work"
end
end
And the child_worker.worker file:
# child_worker.worker
runtime 'ruby'
name 'ChildWorker'
exec 'child_worker.rb', 'ChildWorker'
app.rb:
require 'sinatra'
class MyApp < Sinatra::Application
enable :sessions
if session[:user_id].nil? then
erb :login
end
end
require_relative 'routes/init.rb'
config.ru:
require './app'
run MyApp
Running shotgun config.ru or thin start -R config.ru yields:
app.rb:3:in `<top (required)>': undefined local variable or method `session' for main:Object (NameError)
This is very 101ish. What gives?
I believe the problem is that you don't have that code within a get block or something similar. Basically, sinatra will only know about the session object in the context of a request. Something like this would work for the root url:
require 'sinatra'
class MyApp < Sinatra::Application
enable :sessions
get '/' do
if session[:user_id].nil? then
erb :login
end
end
end
I'm trying to use Webrat in a standalone script to automate some web browsing. How do I get the assert_contain method to work?
require 'rubygems'
require 'webrat'
include Webrat::Methods
include Webrat::Matchers
Webrat.configure do |config|
config.mode = :mechanize
end
visit 'http://gmail.com'
assert_contain 'Welcome to Gmail'
I get this error
/usr/lib/ruby/gems/1.8/gems/webrat-0.6.0/lib/webrat/core/matchers/have_content.rb:57:in 'assert_contain': undefined method assert' for #<Object:0xb7e01958> (NoMethodError)
assert_contain and other assertions are methods of test/unit, try to require it and use webrat from inside a test method:
require 'test/unit'
class TC_MyTest < Test::Unit::TestCase
def test_fail
assert(false, 'Assertion was false.')
end
end
anyway i haven't tested it but I have a working spec_helper for rspec if this can interest you:
require File.dirname(__FILE__) + "/../config/environment" unless defined?(RAILS_ROOT)
require 'spec/rails'
require "webrat"
Webrat.configure do |config|
config.mode = :rails
end
module Spec::Rails::Example
class IntegrationExampleGroup < ActionController::IntegrationTest
def initialize(defined_description, options={}, &implementation)
defined_description.instance_eval do
def to_s
self
end
end
super(defined_description)
end
Spec::Example::ExampleGroupFactory.register(:integration, self)
end
end
plus a spec:
# remember to require the spec helper
describe "Your Context" do
it "should GET /url" do
visit "/url"
body.should =~ /some text/
end
end
give it a try I found it very useful (more than cucumber and the other vegetables around) when there is no need to Text specs (features) instead of Code specs, that I like the most.
ps you need the rspec gem and it installs the 'spec' command to execute your specs.
