黄瓜; Selenium WebDriver - 如何使用Google Chrome作为测试浏览器而不是Firefox [英] Cucumber; Selenium WebDriver - how to use Google Chrome as the testing browser instead of Firefox

问题描述

对于我的Rails 3.1应用程序的黄瓜方案，我使用@javascript标签，因此Selenium被激活。
我得到以下错误：

 找不到Firefox二进制文件（os = macosx）。确保Firefox安装或手动设置路径Selenium :: WebDriver :: Firefox :: Binary.path =（Selenium :: WebDriver :: Error :: WebDriverError）
  

如果可能，我想使用Google Chrome浏览器 - 而不是Firefox（我没有安装）。这可能吗？可以做什么？

事实上，Cucumber / Selenium不应该检测浏览器并使用它吗？

==== EDIT ====

添加完毕后

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

...到features / support / env.rb，
我现在得到这个错误：

 无法找到chromedriver可执行文件。请从http://code.google.com/p/chromium/downloads/list下载服务器，并将其放在PATH上的某个位置。有关详情，请访问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：在我在主页上
  

已从此处下载，我试过把chromedriver可执行文件放在/ usr / bin，但我仍然得到上面的错误。

==== EDIT 2 ====

进一步操作并运行sudo chmod + x / usr / bin / chromedriver之后，我现在运行cucumber后出现一个新的错误：

  @javascript

解决方案

对于capybara，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，并将其复制到你的路径，例如

  $ sudo chmod + x / usr / bin /  chromedriver 
  

For a Cucumber scenario on my Rails 3.1 app, I used the @javascript tag, so Selenium is activated. I get the following error:

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)

If possible, I'd like to use Google Chrome as the browser - not Firefox (which I haven't installed). Is this possible? What could be done?

In fact, shouldn't Cucumber/Selenium detect a browser and use it?

====EDIT====

After adding

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

...to features/support/env.rb, I now get this error:

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'

I've downloaded from here, and I've tried putting the chromedriver executable in /usr/bin, but I still get the above error.

====EDIT 2====

After going one step further and running "sudo chmod +x /usr/bin/chromedriver" as suggested below, I now get a new error after running cucumber:

@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
      unable to connect to chromedriver http://127.0.0.1:57870 (Selenium::WebDriver::Error::WebDriverError)

    Then I should be on the edit memory page for the memory "I played" # features/step_definitions/web_steps.rb:187
      PGError: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
      : ROLLBACK (ActiveRecord::StatementInvalid)

Help appreciated! Getting closer...

解决方案

For capybara, add this to env.rb

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

Download the Chrome driver executable and copy it in you path, e.g. /usr/bin/ and make it executable

$ sudo chmod +x /usr/bin/chromedriver
