I'm attempting to set up system tests with Capybara and Selenium on an existing Rails 5.1 (Upgraded from Rails 4) app that already had capybara based feature tests. Here's what I've done so far.
In the gem file under group :development, :test:
gem 'chromedriver-helper'
gem 'selenium-webdriver'
gem 'rack_session_access'
In the environments/development.rb and environments/test.rb:
config.action_mailer.default_url_options = { host: 'localhost:3000' }
In the spec\rails_helper.rb:
Capybara.register_driver :selenium do |app|
Capybara::Selenium::Driver.new(app, browser: :chrome)
end
Capybara.configure do |config|
config.default_max_wait_time = 10 # seconds
config.default_driver = :selenium
config.app_host = 'http://localhost:3000'
config.server_host = 'localhost'
end
The issues I'm having are both with new systems tests and old feature tests.
With the system tests it appears that Capybara isn't creating a page object as I get undefined local variable or method 'page' Additionally when I duplicate the same test under the feature test directory I don't have this issue.
With the old Capybara feature tests, working with the rackTest driver, a Chrome window opens but I get No route matches [GET] "/rack_session/edit"
config.middleware.use RackSessionAccess::Middleware is already present in the environments/test.rb
Example system test:
require 'rails_helper'
describe User do
let(:user) { create :user }
let(:membership) { create :membership, admin: true}
let(:admin) { create :user, memberships: [membership] }
context 'viewing the index' do
it 'directs you to the appropriate page' do
set_current_user(admin)
visit root_url
click_button 'Manage Users'
expect(page.current_url).to end_with users_path
expect(page).to have_selector 'h1', text: 'Users'
end
end
end
Example feature test:
require 'rails_helper'
describe 'edit an assignment' do
let(:roster) { create :roster }
let(:user) { create :user, rosters: [roster] }
before :each do
Timecop.freeze Date.new(2018, 1, 10)
set_current_user(user)
end
after :each do
Timecop.return
end
context 'returns the user to the appropriate index page' do
let(:date_today) { Date.new(2017, 4, 4) }
let(:start_date) { Date.new(2017, 3, 31) }
let(:month_date) { date_today.beginning_of_month }
it 'redirects to the correct URL' do
visit roster_assignments_url(roster, date: date_today)
visit new_roster_assignment_url(roster, date: start_date)
click_button 'Create'
expect(current_url)
.to eq roster_assignments_url(roster,
date: month_date)
end
In the spec_helper:
def set_current_user(user)
page.set_rack_session user_id: user.id
end
You need to have the gem puma installed. New rails 5 projects have it installed by default, but your app was made in Rails 4, which is why it didn't.
Why is this? Well, if you were to do a bundle update (and I'll admit I can't explain why) you'd get this error when trying to run the specs, which is a lot more explanatory:
System test integration requires Rails >= 5.1 and has a hard dependency on a webserver and `capybara`, please add capybara to your Gemfile and configure a webserver (e.g. `Capybara.server = :webrick`) before attempting to use system tests.
Googling this error led me to this page, which explains Capybara needs a server.
After adding puma, I'm able to run system tests on your application.
A number of issues here.
Why are you setting - config.app_host = 'http://localhost:3000' ??? That would run the tests against your dev instance rather than the test instance Capybara starts. app_host really should only ever need to be set if you are doing subdomain based testing. This could be the reason for the no route error (normally rack_session_access would only be included in the test environment), or that could be caused by having not actually included the middleware as specified in the rack_session_access gem readme.
NEVER do expectations against current_path/current_url directly, instead use the provided matchers or you'll have flaky tests
expect(page).to have_current_path(users_path)
page is just an alias for Capybara.current_session and is a member of the module Capybara::DSL. If it's not available in the scope of your tests that it most likely means Capybara::DSL isn't included. That would normally be done by rspec-rails - https://github.com/rspec/rspec-rails/blob/master/lib/rspec/rails/vendor/capybara.rb#L21 - so it's possible you haven't actually set the test type to 'system'. If it's that it's not available in your spec_helper methods, just using Capybara.current_session instead is usually easier.
My java web application is running on tomcat at http://localhost:8080/
Writing my first spec, home_spec:
require 'spec_helper'
describe "home" do
it "should render the home page" do

end
end
And running:
rspec
I get:

Shouldn't this work because I have included capybara in the spec_helper?
How will it know to visit the correct url? what if my url is localhost:3030 or localhost:8080?

Regarding to rspec issues (https://github.com/rspec/rspec-rails/issues/360)
you should put
config.include Capybara::DSL
in spec_helper.rb, inside the config block.
The default directory that Capybara::RSpec now looks at to include the Capybara::DSL and Capybara::RSpecMatchers is changed from requests to features.
After I renamed my requests directory to features I got the matcher and DSL methods available again without having to explicitly include them.
See the following commit
Also make sure your tests are in the /spec/features directory. According to rspec-rails and capybara 2.0, Capybara v2 and higher will not be available by default in RSpec request specs. They suggest to "...move any tests that use capybara from spec/requests to spec/features."
By default the capybara DSL is included automatically if the file is in spec/requests, spec/integration or if the example group has :type => :request.
Because your file is in spec/home the capybara helpers aren't being included. You can either conform to one of the patterns above or adding include Capybara::DSL should also do the trick (you might also need to replicate some of the before(:each) stuff that would be setup.)

I tried to follow José Valim's advice on faster test suites, but to no avail.
I use Spork and put the AR monkey patch in the Spork.each_run block (see the spec helper below).
However, my request specs fail because the database is not cleaned between runs - specifically, I get errors such as expected 1 record, got X when doing assertions like Model.should have(1).record.
Update
The problem lies with request specs using Javascript. See the following spec - it fails when I use js: true, but not if I remove that (I use RSpec's config.treat_symbols_as_metadata_keys_with_true_values = true, fwiw.)
# encoding: UTF-8
require 'spec_helper'
feature "Create a shift", :js do
scenario %q(
In order to plan the workload
As a coordinator
I want to schedule shifts
And I want to see when they're scheduled for
) do
visit shifts_path
click_link "new_shift_#{Date.current}"
fill_in 'shift_note', with: 'Casper - luk'
click_link_or_button 'submit'
Shift.should have(1).record
Shift.last.begins_at.should == Date.current
page.should have_selector("ol[data-date=\"#{Date.current}\"] li#shift_#{Shift.last.id}")
end
end
I can tell it's related to the DB not being cleaned, because it fails the first time (expected 1 record, got 0), passes the second time (because there's 1 record in the DB) and then fails again on any subsequent runs (expected 1 record, got 2 etc.)
I'm trying to avoid using a gem like DatabaseCleaner, to keep dependencies as few as possible, and to avoid a speed decrease in the test suite.
Any help/info/pointers are greatly appreciated!

After much investigating, the problem seems to be with specs using JS in general, and not really the AR monkey patch.
I've re-phrased the problem in a new question here: RSpec+Capybara request specs w/ JS not working
When running my specs with rspec & capybara, it can't find capybara's visit method. Is there another initialization step I need to do?
$bundle exec rspec spec
/home/brian/projects/expense_track/expense_track/spec/requests/homepage_spec.rb:6:in `block (2 levels) in <top (required)>': undefined method `visit' for #<Class:0xb6572b8> (NoMethodError)
Gemfile:
group :test, :development do
gem "rspec-rails"
gem "capybara"
end
top of my spec_helper.rb:
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'
require 'rspec/autorun'
homepage_spec.rb:
require 'spec_helper'
describe "The home page" do
context "home page exists" do
visit "/"
page.should have_content("elephants")
end
end
Just ran into this issue myself.
So the reason for this is there has been a somewhat undocumented change in Capybara. Capybara now makes the assumption that anything using it needs to be in the spec/features folder and it will make the proper assumptions. Anything left in the spec/requests folder will no longer work. Though there are workarounds.
For a context block you can add the parameter :type => :feature and this will fix that issue or you can change the name of a describe method at the beginning of a spec to feature and this should change it as well.
They announced this change in their Google group: https://groups.google.com/forum/?fromgroups=#!topic/ruby-capybara/5KfxezI-U0Q
Notably, we changed the :type that Capybara assumes your specs run under in RSpec to :feature (previously it was :request). The latest release of spec/features. Alternatively you can use the Capybara Feature DSL (feature instead of describe), which should work without any additional tweaking. If you see errors like undefined method visit, then you're probably encountering this issue. If you're including modules into :request specs, you will probably need to change that to :feature.
This was further discussed in the github issue: https://github.com/jnicklas/capybara/issues/814
A few things to note here :
The changes in Capybara 2.0.x are documented here https://github.com/rspec/rspec-rails/blob/master/Capybara.md . There are changes in the spec directory structure : spec/features, spec/controllers, spec/views, spec/helpers, spec/mailers.
load Capybara dsl explicitly inside your spec_helper
require 'capybara/rails'
require 'capybara/rspec'
include Capybara::DSL
This worked for me.
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
require 'capybara/rails'
RSpec.configure do |config|
config.include Capybara::DSL, :type => :request
end
This enables you to use Capybara's helpers inside spec/requests.
Because RSpec.configure not including capybara DSL in spec_helper.rb
It is an ugly solution, but you can add this to your spec_helper.rb.
module ::RSpec::Core
class ExampleGroup
include Capybara::DSL
include Capybara::RSpecMatchers
end
end
The git issue for this:
https://github.com/rspec/rspec-rails/issues/503
Unfortunately this workaround doesn't do it for me. I still get
NoMethodError:
undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x007fbfeb535298>
The repo is public under: https://github.com/ikusei/Goldencobra_Newsletter
You need to look at the branch '28817499-subscribe'
edit: If i put include Capybara::DSL inside my describe block it works.
but including Capybara::DSL in the global scope is not recommended!
Because I do not know a good way.
For rspec 3 and rails, make sure you are using require "rails_helper", instead of require "spec_helper".
Otherwise, review the latest changes to rspec 3 & rspec-rails and Capybara 2.0.x.
