I'm just experimenting a little with Cucumber and Capybara.
I'm writing a class that will perform some user admin for me.
I have the following class:
class UserAdmin
def initialize(data)
#data = data
end
def add_user
require 'rspec/expectations'
require 'capybara/cucumber'
require 'capybara/helpers'
#data.hashes.each do |user_details|
load_user_data(user_details)
fill_in('firstname', with: #first_name)
fill_in('surname', with: #last_name)
fill_in('username', with: #new_username)
fill_in('usernameConfirmation', with: #confirm_new_username)
click_button_add_user
end
end
When I try and create an instance of this class, I get `NoMethodError: undefined method fill_in' for #
I thought by requieing Capybara etc, I could use their methods in my class.
Clearly I'm wrong, could anyone point out where I've gone wrong please?
You should include Capybara::DSL:
require 'capybara/dsl'
class UserAdmin
include Capybara::DSL
Capybara.run_server = false
# ...
end

I have a module and class in a file lib/crawler/page-crawler.rb that looks like this:
require 'oga'
require 'net/http'
require 'pry'
module YPCrawler
class PageCrawler
attr_accessor :url
def initialize(url)
#url = url
end
def get_page_listings
body = Net::HTTP.get(URI.parse(#url))
document = Oga.parse_html(body)
document.css('div.result')
end
newpage = PageCrawler.new "http://www.someurl"
#listings = newpage.get_page_listings
#listings.each do |listing|
bizname = YPCrawler::ListingCrawler.new listing['id']
end
end
end
Then I have another module & class in another file lib/crawler/listing-crawler.rb that looks like this:
require 'oga'
require 'pry'
module YPCrawler
class ListingCrawler
def initialize(id)
#id = id
end
def extract_busines_name
binding.pry
end
end
end
However, when I try to run this script ruby lib/yp-crawler.rb which executes the page-crawler.rb file above and works without the YPCrawler call, I get this error:
/lib/crawler/page-crawler.rb:23:in `block in <class:PageCrawler>': uninitialized constant YPCrawler::ListingCrawler (NameError)
The issue is on this line:
bizname = YPCrawler::ListingCrawler.new listing['id']
So how do I call that other from within my iterator in my page-crawler.rb?
Edit 1
When I just do `ListingCrawler.new listing['id'], I get the following error:
uninitialized constant YPCrawler::PageCrawler::ListingCrawler (NameError)
Edit 2
Here is the directory structure of my project:
Edit 3
My yp-crawler.rb looks like this:
require_relative "yp-crawler/version"
require_relative "crawler/page-crawler"
require_relative "crawler/listing-crawler"
module YPCrawler
end
In your yp-crawler.rb file, based on the structure that you posted, you should have something like:
require 'yp-crawler/version'
require 'crawler/listing-crawler'
require 'crawler/page-crawler'
Try this, in your yp-crawler.rb add the line:
Dir["#{File.dirname(__FILE__)}/crawler/**/*.rb"].each { |file| load(file) }
That should automatically include all files in your /crawler directory at runtime. Might want to do the same for the other directories.
Let me know if that helps :)
I'm attempting to use the Geocoder gem with a DataMapper model in a Sinatra application.
environment.rb:
require 'rubygems'
require 'bundler/setup'
require 'dm-core'
require 'dm-timestamps'
require 'dm-validations'
require 'dm-aggregates'
require 'dm-migrations'
require 'dm-types'
require 'geocoder'
require 'sinatra' unless defined?(Sinatra)
# load models
$LOAD_PATH.unshift("#{File.dirname(__FILE__)}/lib")
Dir.glob("#{File.dirname(__FILE__)}/lib/*.rb") { |lib| require File.basename(lib, '.*') }
DataMapper.setup(:default, (ENV["DATABASE_URL"] || "sqlite3:///#{File.expand_path(File.dirname(__FILE__))}/#{Sinatra::Base.environment}.db"))
DataMapper.finalize
DataMapper.auto_upgrade!
lib/location.rb:
class Location
include DataMapper::Resource
include Geocoder::Model::Base
property :id, Serial
property :address, String, :required => true
# geocoder gem
geocoded_by :address, :latitude => :lat, :longitude => :lng
# geocoder
after_validation :geocode, :if => :address_changed?
end
When I attempt to start an IRB session, an exception is generated:
irb> require './environment'
NameError: uninitialized constant Geocoder::Model
...
What am I not understanding?
First up, it looks like the Geocode gem won't have direct support for Datamapper, as per this issue.
Second, when you include a module inside a class, the methods are available to the instance of the class, and not at the class level. For example:
module Name
def name
puts "Module"
end
end
class SomeClass
include Name
end
SomeClass.new.name # => "Module"
This works because when you include a module, that module gets added to the ancestor chain of that class. Any methods that get sent to the instance which are not available on the instance are forwarded to the ancestors. However, there's another method called extend which adds the methods at a class-level rather than at instance level:
# module definition same as before
class SomeClass
extend Name
name # works!
end
Inorder to get class-level inclusion, there is another way (which is what the Geocoder gem uses for supported models:
# module code same as before
module Name
def name
puts "Module"
end
def self.included(klass)
klass.extend(self)
end
end
The included hook is provided for models which can be overridden to do something when the include Name step executes. Since there's no Datamapper specific module that is not executing this step, you see that error.
Same app, different problem. I'm working on an app using the Dan Benjamin "Meet Sinatra" screencast as a reference. I'm trying to include a custom authentication module, which is housed in a lib folder (lib/authentication.rb). I am requiring that line at the top of my code, but when I try to load the page, it claims there is no such file to load.
Any thoughts?
Here's the top of my main Sinatra file:
require 'sinatra'
require 'rubygems'
require 'datamapper'
require 'dm-core'
require 'lib/authorization'
DataMapper::setup(:default, "sqlite3://#{Dir.pwd}/entries.db")
class Entry
include DataMapper::Resource
property :id, Serial
property :first_name, String
property :last_name, String
property :email, String
property :created_at, DateTime
end
# create, upgrade, or migrate tables automatically
DataMapper.auto_upgrade!
helpers do
include Sinatra::Authorization
end
And the actual Module:
module Sinatra
module Authorization
def auth
#auth ||= Rack::Auth::Basic::Request.new(request.env)
end
def unauthorized!(realm="Short URL Generator")
headers 'WWW-Authenticate' => %(Basic realm="#{realm}")
throw :halt, [ 401, 'Authorization Required' ]
end
def bad_request!
throw :halt, [ 400, 'Bad Request' ]
end
def authorized?
request.env['REMOTE_USER']
end
def authorize(username, password)
if (username=='topfunky' && password=='peepcode') then
true
else
false
end
end
def require_admin
return if authorized?
unauthorized! unless auth.provided?
bad_request! unless auth.basic?
unauthorized! unless authorize(*auth.credentials)
request.env['REMOTE_USER'] = auth.username
end
def admin?
authorized?
end
end
end
Then, on any of the handlers I want to protect, I put "require_admin."
Assuming you're using Ruby 1.9, the default $LOAD_PATH no longer includes the current directory. So while statements like require 'sinatra' work just fine (because those gems are in $LOAD_PATH), Ruby doesn't know that your lib/authorization file is located relative to your main Sinatra file.
You can add the Sinatra file's directory to the load path, and then your require statements should work fine:
$LOAD_PATH.unshift(File.dirname(__FILE__))
require 'sinatra'
require 'rubygems' # Not actually needed on Ruby 1.9
require 'datamapper'
require 'dm-core'
require 'lib/authorization'
Personnaly, I use a "relative" path since I work with Ruby 1.9.2 :
require 'sinatra'
require 'rubygems' # Not actually needed on Ruby 1.9
require 'datamapper'
require 'dm-core'
require './lib/authorization'
But I never check what would happen if my code should work on Ruby 1.8.6 again.
I have a class that I want to use in many test cases:
require 'rubygems'
require 'test/unit'
require 'watir'
class Tests < Test::Unit::TestCase
def self.Run(browser)
# make sure Summary of Changes exists
assert( browser.table(:class, "summary_table_class").exists? )
# make sure Snapshot of Change Areas exists
assert( browser.image(:xpath, "//div[#id='report_chart_div']/img").exists? )
# make sure Integrated Changes table exists
assert( browser.table(:id, 'change_table_html').exists? )
end
end
However, when run in one of my test cases:
require 'rubygems'
require 'test/unit'
require 'watir'
require 'configuration'
require 'Tests'
class TwoSCMCrossBranch < Test::Unit::TestCase
def test_two_scm_cross_branch
test_site = Constants.whatsInUrl
puts " Step 1: go to the test site: " + test_site
ie = Watir::IE.start(test_site)
Tests.Run(ie)
end
end
I get the error:
NoMethodError: undefined method `assert' for Tests:Class
C:/p4/dev/webToolKit/test/webapps/WhatsIn/ruby-tests/Tests.rb:8:in `Run'
What's missing? Thanks!
assert() is an instance method on TestCase so would only be available to instances of Tests. You are calling it inside a class method so Ruby is looking for a class method in Tests which doesn't exist.
A better way to do this is to make Tests a module and the Run method an instance method:
module Tests
def Run(browser)
...
end
end
Then include the Tests module in your test class:
class TwoSCMCrossBranch < Test::Unit::TestCase
include Tests
def test_two_scm_cross_branch
test_site = Constants.whatsInUrl
puts " Step 1: go to the test site: " + test_site
ie = Watir::IE.start(test_site)
Run(ie)
end
end
which will make the Run method available to the test and Run() will find the assert() method in the test class.
It might be worth a try to remove the asserts all together, and just use .exists?.
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.
