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 应用程序上的 Cucumber 场景，我使用了@javascript 标签，因此 Selenium 被激活.我收到以下错误:

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)

如果可能，我想使用 Google Chrome 作为浏览器 - 而不是 Firefox(我还没有安装).这可能吗?可以做什么?

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?

实际上，Cucumber/Selenium 不应该检测浏览器并使用它吗?

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

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:

...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'

我从 这里下载，我已经尝试将 chromedriver 可执行文件放在/usr/bin 中，但仍然出现上述错误.

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====

在更进一步并按照下面的建议运行sudo chmod +x/usr/bin/chromedriver"后，我现在在运行 cucumber 后得到一个新错误:

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

        This probably means the server terminated abnormally

推荐答案

对于水豚，将这个添加到 env.rb

For capybara, add this to 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

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
