Capybara in separate ruby file - capybara

in some.rb file i put that code:
require 'rubygems'
require 'capybara'
require 'capybara/dsl'
Capybara.run_server = false
Capybara.current_driver = :selenium
module MyTest
class Test
include Capybara::DSL
def first
visit('http://www.google.com')
save_and_open_page
# fill_in('?',:with => term)
# page.should have_css('div#res li')
end
end
end
t = MyTest::Test.new
t.first
and try to run this file: ruby some.rb
and in saved page - i get google page, but in other coding...
how can i fix this ? ( i want put in google search some query - but in this coding i don't know what put in fill_in )

Check the below link
http://blog.dharanasoft.com/2012/03/19/a-search-spider-in-ruby-using-capybara-webkit/
The example is pretty helpful.
Let me know in comments if you need a more detailed explanation.
fill_in "q", :with => ARGV[0] || "I love Ruby!"
In the above statement, q is the google search box id(you can get it through firebug add on in firefox) and the last statement "I Love Ruby" is the query that will get pasted in the search box once the code is executed.

What can cause Capybara::Poltergeist::TimeoutError: in group testing that doesn't individually?

A Rails app that uses remote testing to test a CakePHP app running on a Vagrant Ubuntu VM.
My OS is macOS High Sierra.
'rspec/rails'
'capybara/rails'
'capybara/mechanize'
'capybara/poltergeist'
'phantomjs'
If I run rspec ./spec/features/my_tests_folder/,
the first 2 tests in the folder always pass and the rest always end up with Capybara::Poltergeist::TimeoutError:.
If I run any of the tests in that folder individually, they ALL pass ALWAYS.
There are 7 test files total. They each have 1 feature with 1 scenario. All are js: true.
I have tried increasing :timeout in Capybara.register_driver and increasing default_max_wait_time in Capybara.configure. Neither changed the outcome.
I've also played around with Capybara.reset! after and before each test. It didn't seem to matter, either.
When I ran this with config.order = :random, sometimes 5 out of 7 had the erros, sometimes only 2 out of 7. But, there were always some errors and some passing. Also, every test was in the errors group at least once.
I'm running out of ideas. What could cause something like this?
UPDATE (to include Capybara and Poltergeist configs and example of a failing test):
Configs in rails_helper.rb:
Capybara.register_driver :poltergeist do |app|
options = {
:timeout => 90, # default is 30
:js_errors => false,
:phantomjs => Phantomjs.path,
# :debug => true
}
Capybara::Poltergeist::Driver.new(app, options)
end
Capybara.register_driver :mechanize do |app|
driver = Capybara::Mechanize::Driver.new(app)
driver.configure do |agent|
agent.user_agent_alias = 'Mac Safari'
end
driver
end
Capybara.configure do |config|
config.run_server = false
config.app_host = "http://my_vm_domain.com"
config.javascript_driver = :poltergeist
config.default_driver = :mechanize
config.default_max_wait_time = 10 # default is 2
end
Example of failing test (not failing, but getting Capybara::Poltergeist::TimeoutError:):
require 'rails_helper'
feature 'agente visualiza estoques de um passeio', js: true do
scenario 'com sucesso' do
agente_log_in
visit '/roteiro/show/723'
find(:partial_href, 'new_passeio/723').click
select 'Passeio Teste', from: 'passeio_produto'
fill_in 'passeio_data', with: '11/11/2017'
within('button#estoque_controls_0') do
within('div#estoque_0_hora') do
expect(page).to have_content('07:30')
end
within('span#estoque_0_vagas') do
expect(page).to have_content('3')
end
end
within('button#estoque_controls_1') do
within('div#estoque_1_hora') do
expect(page).to have_content('10:00')
end
within('span#estoque_1_vagas') do
expect(page).to have_content('5')
end
end
end
end
Code from agente_log_in.rb in support folder:
def agente_log_in
Capybara.app_host = "http://my_vm_domain.com"
visit '/usuario/logout'
visit '/'
fill_in 'data[AdmUsuario][usuario]', with: 'agente'
fill_in 'data[AdmUsuario][senha]', with: 'pa$$w0rd'
click_on 'Entrar'
end
Code for that :partial_href find:
module Selectors
Capybara.add_selector(:partial_href) do
xpath {|href| XPath.descendant[XPath.attr(:href).contains(href)] }
end
end
Everything is fine with the other tests that are in the app's other folders. They're also fine if I run the tests in this folder individually. The problem only seems to happen when I run THIS specific folder as a whole.
After including the extra information requested by Thomas Walpole, I continued searching and studying possibilities.
I eventually came across poltergeist's issue #781 on GitHub, which describes a situation very similar to mine, and eventually presents a wait_for_ajax solution.
Before implementing it in my project, I read more about waiting for Ajax and found this post very helpful, too.
In the end, I chose jasonfb's code from GitHub because it seemed more thorough and informative.
It worked like a charm! My tests now pass consistently. I was even able to remove customization for :timeout and default_max_wait_time.
The CakePHP app in question is very js heavy and the specific part that this folder tests is particularly full of Ajax requests.

typeahead.js test failing on Rails 4 with Cucumber and Capybara-Webkit

I have the following Cucumber feature testing an input form using typeahead.js:
#javascript
Scenario: Creating a battery using typeahead
When I create a new battery using typeahead
Then I should be on the show battery page
And I should see the battery created message
The test fails on the second step with the following error message:
ActiveRecord::RecordNotFound (ActiveRecord::RecordNotFound)
./features/step_definitions/admin/car_part_steps/battery_steps.rb:37:in `/^I should be on the show battery page$/'
features/admin/creating_car_parts/creating_batteries.feature:20:in `Then I should be on the show battery page'
The relevant step definitions are as follows:
When /^I create a new battery using typeahead$/ do
select_from_typeahead :field => 'battery_manufacturer_typeahead',
:select => #manufacturer.name
fill_in 'Type', :with => '700W'
click_button 'Create Battery'
end
Then /^I should be on the show battery page$/ do
battery = Battery.find_by_type_and_manufacturer_id!('700W', #manufacturer.id)
current_path.should == admin_battery_path(battery)
page.should have_content(battery.type)
end
The select_from_typeahead function is as follows:
def select_from_typeahead(params)
params[:js_field] ||= params[:field]
params[:select_typeahead] ||= params[:select]
fill_in params[:field], :with => params[:select][0, 2]
page.execute_script "$('##{params[:js_field]}').trigger('focus')"
page.execute_script "$('##{params[:js_field]}').trigger('keydown')"
sleep 0.5
page.execute_script "$('.tt-suggestion:contains(\"#{params[:select_typeahead]}\")').trigger('mouseenter').trigger('click')"
end
The problem appears not to have anything to do with the typeahead itself however, as the code works in the browser, and if I add some debug output, I notice that the battery gets saved to the database in the first step when running the test as well, it just mysteriously disappears before the second step runs.
I think it's an issue with database_cleaner, as I know that doesn't play nice with Javascript when set to use transactions, but I've already tried setting it to use truncation instead and disabled transactional fixtures and it still doesn't work.
My features/support/env.rb currently looks like this:
require 'simplecov'
SimpleCov.start 'rails'
require 'cucumber/rails'
Capybara.default_selector = :css
Capybara.javascript_driver = :webkit
ActionController::Base.allow_rescue = false
Cucumber::Rails::World.use_transactional_fixtures = false
DatabaseCleaner.strategy = :truncation
Cucumber::Rails::Database.javascript_strategy = :truncation
My environment is as follows:
rails 4.0.2
cucumber 1.3.10
cucumber-rails 1.4.0
capybara 2.2.0
capybara-webkit 1.1.0
database_cleaner 1.2.0
Am I missing something, is there some other way database_cleaner might still interfere with my test, or is it something else entirely that I haven't thought of?
Any ideas would be very welcome!
I don't think it has to do with Database Cleaner. That wouldn't do cleanup until the end of your scenario. To debug, I highly recommend installing Capybara Screenshot so that you can see exactly what is going on in your page. It provides you the method screenshot_and_open_image, which you can use to pop open an image of what the browser looks like at that exact moment. My guesses are that:
Your jQuery isn't doing what you expect because of timing issues - have you tried longer pauses?
Your transaction isn't committed. Have you looked in test.log to see if the transaction was committed?
Is your form failing validation? Try putting a screenshot_and_open_image at the beginning of your I should be on the show battery page step to see. Another thing I use is a shared step like this, so that I can add screenshots in my scenarios for debugging:
And /^I take a screenshot$/ do
Capybara::Screenshot.screenshot_and_open_image
end

Why are these Rspec examples not occuring within a DB transaction?

I'm writing a typical test in my application where I create a model through a form and check that the model count equals 1.
The test fails because there are already multiple records in the test DB, and this count increases each time I run my tests. It looks like each example isn't happening inside a transaction (being rolled back) like it's supposed to, and I don't know why.
I have this line in my spec_helper.rb file, which is supposed to run each example in a transaction:
config.use_transactional_fixtures = true
Here is my spec that keeps generating model objects:
require 'spec_helper'
describe "Admin artwork pages" do
subject { page }
let(:gallery) { FactoryGirl.create(:gallery) }
describe "artwork creation" do
context "with valid attributes" do
it "creates new artwork" do
visit admin_gallery_artworks_path(gallery_id: gallery.id)
click_link 'Add new artwork'
fill_in 'artwork_title', with: 'Still Life'
click_button 'Create Artwork'
page.should have_text 'Successfully created'
Artwork.count.should eq 1
end
end
end
end
Here's the error message from Rspec:
Failures:
1) Admin artwork pages artwork creation with valid attributes creates new artwork
Failure/Error: Artwork.count.should eq 1
expected: 1
got: 153
(compared using ==)
Edit: Contents of my spec_helper.rb file:
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rails'
require 'capybara/rspec'
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
RSpec.configure do |config|
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"

# instead of true.
config.use_transactional_fixtures = true

end
I'm using Rails 4.0.0.rc1, Ruby 1.9.3, FactoryGirl and rspec-rails 2.13.0 Thanks for any help.
It turns out that Rails 4 is supported starting in rspec-rails 2.13.1 - I was using 2.13.0. After upgrading, the specs took place within a transaction like they were supposed to.
Thanks to everyone who took the time to post help.
I believe the problem is the way you have your test written and less to due with config.use_transactional_fixtures = true. Focus on the bottom of the error that says (compared using ==)
Try to use the expecting change rspec syntax instead
Change this:
click_button 'Create Artwork'
page.should have_text 'Successfully created'
Artwork.count.should eq 1
To this:
expect { click_button 'Create Artwork' }.to change { Artwork, :count }.by(1)
page.should have_text 'Successfully created'
Let me know if this helps
You're running a request spec: when you call visit the code under test is run in a server instance (in the same process). In particular this means that it's using a different thread.
As a result the application code ends up using a different database connection, and since transactions are a per connection thing there is no transaction used when your controller inserts records into the database.
There are several ways to address this. One is to abandon rspec's transactional fixtures and use the database_cleaner gem. You can set it up so that controller and model specs use transactions but request specs use truncate to forcibly clear out tables.
Another approach is to try and force both the spec code and the server code to use the same database connection, this eliminating the problem. You can see this approach in this answer. In my experience this works pretty well until you start using a capybara driver such as poltergeist which will run any javascript on the page and your page fires ajax requests.
The approach I've been using is to set the active record connection pool size to 1: there is only 1 connection allowed so everyone will use the same one. You do then have to do some work to ensure that connections are returned to the pool or your spec just hangs.
I wrote up the details a while ago as a blog post, but in a nutshell you need to
call ActiveRecord::Base.clear_active_connections! before calling methods like visit, click and so on
hack config.middleware.insert_before ActiveRecord::ConnectionAdapters::ConnectionManagement so that it clears the connection after each request (by default it doesn't do this in tests).

Trying to test omniauth with rspec & Capybara, failing

Using Rails 3.2 and the latest Rspec and Capybara, which means my Capybara specs live in spec/features.
I'm really new to Rails and testing, but I want to get used to testing. I ended up implementing OAuth before testing it. I finally got it working, and now I'm trying to retroactively test it (so I at least know if it breaks in the future). I'm trying to follow this tutorial, but things aren't working. Here's what I did:
1) Created spec/support/integration_spec_helper.rb with:
module IntegrationSpecHelper
def login_with_oauth(service = :google)
visit "/auth/#{service}"
end
end
2) Modified spec/spec_helper to include config.include IntegrationSpecHelper, :type => :request inside the Rspec.configure do block.
3) Created spec/features/omniauth_spec.rb with:
require 'spec_helper'
feature 'testing oauth' do
scenario 'should create a new tiger' do
login_with_oauth
visit new_tiger_path
fill_in 'tiger_name', :with => 'Charlie'
fill_in 'tiger_blood', :with => 'yes'
click_on 'Create Tiger'
page.should have_content("Thanks! You are a winner!")
end
end
Of course it's going to fail (I don't have tigers in my app) but I want it to fail on visit new_tiger_path. Instead, running the spec, I get:
1) testing oauth should create a new tiger
Failure/Error: login_with_oauth
NameError:
undefined local variable or method `login_with_oauth' for #<RSpec::Core::ExampleGroup::Nested_3:0x83355d8>
# ./spec/features/omniauth_spec.rb:4:in `block (2 levels) in <top (required)>'
So basically, it says there's no such thing login_with_oauth. This must be a really basic error, as my code isn't included for some reason.
I'm not using spork (trying to keep things simple).
Any idea what the problem might be? Thanks in advance!
If you are trying to use oauth from google, you'll want to change:
def login_with_oauth(service = :google)
to:
def login_with_oauth(service = :google_oauth2)
:google_oauth2 should also be the first argument to OmniAuth.config.add_mock, i.e.:
OmniAuth.config.add_mock(
:google_oauth2,
{
:info => {
:email => 'test#some_test_domain.com',
:name=>'Test User'
}
})
Don't forget to change:
config.include(IntegrationSpecHelper, :type => :request)
to:
config.include(IntegrationSpecHelper, :type => :feature)
inside the RSpec.configure block, as Christoph noted above.
A little late, but maybe I can help.
Got the same problem. It's caused by
config.include IntegrationSpecHelper, :type => :request
The paramater ':type' needs to be changed to ':feature' because you write a rspec feature test.
Solution:
config.include IntegrationSpecHelper, :type => :feature
Unfortunately this causes further problems, I couldn't solve yet.

Email spec doesn't match body content in Rails

I'm using email_spec gem to test a simple email, but for some reason the body content appears to be empty:
1) ContactMailer welcome email to new user renders the body
Failure/Error: mail.should have_body_text("Hi")
expected the body to contain "Hi" but was ""
# ./spec/mailers/contact_mailer_spec.rb:17:in `block (3 levels) in <top (required)>'
Every other example passes. The template file is called welcome_email.text.erb. Not sure why body is not matched, but the email does have a body when it gets sent.
Edit: the Rspec code is:
let(:mail) { ContactMailer.welcome_email(email) }
it "renders the body" do
mail.should have_body_text("Hi")
end
The best way I've found to do this is:
it "contains a greeting" do
mail.html_part.body.should match /Hi/
end
You can also use text_part in place of html_part if you want to check the plain text part of a multipart message.
Also note that others may recommend using #encoded, but I had trouble using that with long URLs, as they may get line-wrapped during the encoding process.
So, I was experiencing the same thing. I was trying to test my mailers without loading all of Rails.
What finally solved my problem was adding this to my test:
(note that my test is in test/unit/mailers/my_mailer_test.rb - you may have to adjust paths)
ActionMailer::Base.delivery_method = :test
ActionMailer::Base.view_paths = File.expand_path('../../../../app/views', __FILE__)
Basically, without the view paths pointing to your views directory, the template is not found and all the parts (html, text, etc) are blank.
NOTE: The directory specified is NOT the one the actual templates are in. The mailer knows to look for a directory in the template root named after the class itself.
Here's a sample in minitest/spec
require 'minitest/spec'
require 'minitest/autorun'
require "minitest-matchers"
require 'action_mailer'
require "email_spec"
# NECESSARY TO RECOGNIZE HAML TEMPLATES
unless Object.const_defined? 'Rails'
require 'active_support/string_inquirer'
class Rails
def self.env
ActiveSupport::StringInquirer.new(ENV['RAILS_ENV'] || 'test')
end
end
require 'haml/util'
require "haml/template"
end
# END HAML SUPPORT STUFF
require File.expand_path('../../../../app/mailers/my_mailer', __FILE__)
ActionMailer::Base.delivery_method = :test
ActionMailer::Base.view_paths = File.expand_path('../../../../app/views', __FILE__)
describe MyMailer do
include EmailSpec::Helpers
include EmailSpec::Matchers
let(:the_email){ MyMailer.some_mail() }
it "has the right bit of text" do
the_email.must have_body_text("some bit of text")
end
end
