黄瓜; Selenium WebDriver - 如何使用谷歌浏览器作为测试浏览器而不是Firefox

Question

对于我的Rails 3.1应用程序上的Cucumber场景,我使用了@javascript标记,因此激活了Selenium.我收到以下错误:

Could not find Firefox binary (os=macosx). Make sure Firefox is installed or set the path manually with Selenium::WebDriver::Firefox::Binary.path= (Selenium::WebDriver::Error::WebDriverError)

如果可能的话,我想使用谷歌浏览器作为浏览器 - 而不是Firefox(我还没有安装).这可能吗？可以做些什么？

事实上,Cucumber/Selenium不应该检测浏览器并使用它吗？

添加后

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

...到features/support/env.rb,我现在收到此错误:

Unable to find the chromedriver executable. Please download the server from http://code.google.com/p/chromium/downloads/list and place it somewhere on your PATH. More info at http://code.google.com/p/selenium/wiki/ChromeDriver. (Selenium::WebDriver::Error::WebDriverError)
  ./features/step_definitions/web_steps.rb:45:in `/^(?:|I )am on (.+)$/'
  features/update_memories.feature:11:in `Given I am on the home page'

我从这里下载了,我已经尝试将chromedriver可执行文件放在/ usr/bin中,但我仍然遇到上述错误.

进一步运行"sudo chmod + x/usr/bin/chromedriver"之后,如下所示,我现在运行黄瓜后出现一个新错误:

@javascript
  Scenario: navigate to memory update page from home page              # features/update_memories.feature:11
    Given I am on the home page                                        # features/step_definitions/web_steps.rb:44

    Then I should be on the edit memory page for the memory "I played" # features/step_definitions/web_steps.rb:187

        This probably means the server terminated abnormally

对于水豚,将其添加到env.rb

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

下载Chrome驱动程序可执行文件并将其复制到您的路径中,例如/ usr/bin /并使其可执行

$ sudo chmod +x /usr/bin/chromedriver
