ruby-on-rails - cucumber 测试突然停止

Question

我有这样的功能:

Feature: Searching chats
In order to find chats
As an user
I want to find different chats by username or ad name

Background:
  Given System prepares for chats
  And There is a few machines with names:
    | machine_1 |
    | machine_2 |
    | machine_3 |
  And There is a few services with names:
    | service_1 |
    | service_2 |
    | service_3 |
  And I have chats with ads owners

Scenario: Searching chats
  When I am logged in as a "user"
  And I go to chats page   # <- stops here
  Then I should see search results when I fill form with:
    | input  | results |
    | ma     | machine_1, machine_2, machine_3 |
    | se     | service_1, service_2, service_3 |                                                                         

当我启动 cucumber 功能(或场景)时，它突然在“我转到聊天页面”步骤停止，没有任何错误消息。结果看起来像:

[alex@MacBookPro ~/my_project | master]$ cucumber features/chat/search.feature
Using the default profile...
@javascript
Feature: Searching chats
  In order to find chats
  As an user
  I want to find different chats by username or ad name

  Background:                               # features/chat/search.feature:8
    Given System prepares for chats         # features/step_definitions/chats.steps.rb:11
    And There is a few machines with names: # features/step_definitions/machine.steps.rb:10
      | machine_1 |
      | machine_2 |
      | machine_3 |
    And There is a few services with names: # features/step_definitions/service.steps.rb:144
      | service_1 |
      | service_2 |
      | service_3 |
    And I have chats with ads owners        # features/step_definitions/chats.steps.rb:5

  Scenario: Searching chats                                 # features/chat/search.feature:20
    When I am logged in as a "user"                         # features/step_definitions/user.steps.rb:68
    And I go to chats page                                  # features/step_definitions/chats.steps.rb:17
[alex@MacBookPro~/my_project | master]$

这是我的“下降”步骤:

When /^I go to chats page$/ do
  visit root_path

  within('.global-menu') do
    click_on username(@current_user)
    click_on I18n.t('views.menu.profile.links.dashboard')
  end

  click_on I18n.t('views.menu.profile.links.chats')
end

Then(/^I should see search results when I fill form with:$/) do |table|
  table.hashes.each do |search_data|
    ### searching ###
    @page.query.set search_data['input']

    # for AJAX search
    sleep 1

    ### show results ###
    search_data['results'].split(', ').each do |res|
      page.should have_content res.mb_chars.upcase
    end

    within('#chats') do
      page.all('.chat').length.should == search_data['results'].split(', ').size
    end
  end
end

我正在使用带有 cucumber 的 capybara webkit。那是我的 env.rb:

require 'rubygems'
require 'spork'
require 'capybara'
require 'capybara/rspec'
require 'selenium-webdriver'
require 'site_prism'
require 'capybara-screenshot/cucumber'
# require 'cucumber/rails'


# 1) Tag your scenario (or feature) with @allow-rescue
#
# 2) Set the value below to true. Beware that doing this globally is not
# recommended as it will mask a lot of errors for you!
#
# ActionController::Base.allow_rescue = false

#############################################################################

ENV['SKIP_RAILS_ADMIN_INITIALIZER'] = 'false'                                   # This fixes weird errors with cucumber + rails_admin (http://makandracards.com/makandra/9597-rake-spec-+-rails_admin-weirdly-failing-specs).

Before do
  DatabaseCleaner.strategy = :truncation

  DatabaseCleaner.clean
  FactoryGirl.create(:setting)
  ContactType.generate_contact_types
  ContactType.generate_ims
end

Spork.prefork do
  require 'cucumber/rails'
  require 'email_spec' # add this line if you use spork
  require 'email_spec/cucumber'
  Capybara.default_selector = :css
end

Spork.each_run do
  ActionController::Base.allow_rescue = false

  begin
    DatabaseCleaner.strategy = :truncation
  rescue NameError
    raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
  end

  Capybara.register_driver :webkit do |app|
    Capybara::Webkit::Driver.new(app, :stderr => nil)
  end

  Capybara.javascript_driver = :webkit

  Cucumber::Rails::Database.javascript_strategy = :truncation
end

当我将我的项目更新到 rails4 时出现问题。有任何想法吗？

Answer 1

我管理的很多开发人员都找到了 Capybara-webkit真的有问题和不一致。
poltergeist/PhantomJS比它有很多优势。一般它:

更具确定性，因为问题场景更可能始终失败而不是片状

较少依赖机器；我们的套件现在在所有测试环境中的行为几乎相同

提供更好的错误信息

出现 Javascript 错误时失败，即使测试会通过

不挂，和

更容易安装。
