使用 cucumber 、 capybara 和 Selenium 进行设置，但某些场景只能随机运行。
正在运行
rvm 上的 ruby 1.8.6
导轨 2.3.8
selenium 弹出 firefox 3.6

我试图添加这个但没有运气:

with_scope(selector) do
  click_button(button)
  selenium.wait_for_page_to_load
end

错误输出有时是:

>  Given I am logged in and have created newsletter and subscribers                           # features/step_definitions/newsletter_send_steps.rb:108
      end of file reached (EOFError)

其他时候:

      features/enhanced/newsletter_send1.feature:7:in `Given I am logged in and have created newsletter and subscribers'

有时它只是有效....

这就是我的 env.rb 的样子

ENV["RAILS_ENV"] ||= "cucumber"
require File.expand_path(File.dirname(__FILE__) + '/../../config/environment')

require 'cucumber/formatter/unicode' # Remove this line if you don't want Cucumber Unicode support
require 'cucumber/rails/world'
require 'cucumber/rails/active_record'
require 'cucumber/web/tableish'
require 'capybara/rails'
require 'capybara/cucumber'
require 'capybara/session'
require 'cucumber/rails/capybara_javascript_emulation' 
require "selenium-webdriver"

Capybara.default_driver = :selenium
Capybara.default_wait_time = 5 
Capybara.ignore_hidden_elements = false
Capybara.default_selector = :css

ActionController::Base.allow_rescue = false

require 'database_cleaner'
DatabaseCleaner.strategy = :truncation

Before do
 Capybara.reset_sessions!
 DatabaseCleaner.clean
end

Cucumber::Rails::World.use_transactional_fixtures = false

cucumber 步骤:
鉴于我在注册页面上
我在“正文”中用“jeppsipeppsi@arcticelvis.com”填写“user_login”
我在“body”中用“secret”填写“user_password”
然后我在“body”中用“secret”填写“user_password_confirmation”
然后我检查了“body”中的“terms_of_use”
然后我在“body”中按下“create_user_button”

任何见解都会很棒:)

最佳答案

这是 HTTP 模拟，如果您(完全)从您的环境中删除 fakeweb 或 webmock，它应该会再次工作。

Adam Greene 关于设置 Curb 的最后评论确实有效: Selenium::WebDriver.for :firefox, :http_client => Selenium::WebDriver::Remote::Http::Curb

Read the thread on the Capybara group.

我们遇到的问题是使用 fakeweb 或 webmock 回放记录的 http 流量，因为网络驱动程序现在是 Curb。因此，如果您的目标是伪造 Capybara 上的流量，您将再次进行浏览器测试，但您将无法通过同一浏览器播放流量。 (我们正在使用 VCR 进行录制。)

添加 Curb 支持在 Fakeweb 的 Github Issues 网站上被列为“票”。
