Question

我正在尝试对javascript代码运行一些验收测试。然而，当我尝试将Capybara与Selenium一起使用时，我不断得到以下内容：

>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:1234, CTRL+C to stop
FF>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:1234, CTRL+C to stop
F

Failures:

  1) end to end acceptance test shows that x wins when it does
     Failure/Error: @application.start
     Selenium::WebDriver::Error::WebDriverError:
       Unable to find the chromedriver executable. Please download the server from http://code.google.com/p/chromedriver/downloads/list and place it somewhere on your PATH. More info at http://code.google.com/p/selenium/wiki/ChromeDriver.>> Thin web server (v1.3.1 codename Triple Espresso)
     # ./spec/acceptance/application_driver.rb:24:in `start'
     # ./spec/acceptance/end_to_end.rb:6:in `block (2 levels) in <top (required)>'

下面的代码是启动驱动程序的原因。我从http://code.google.com/p/chromedriver/downloads/list下载了相应的文件，然后通过运行PATH = $ PATH：/ directory / where / chromedriver / exists并导出PATH将其放入我的Path中，并使其可执行但仍然出错。有什么我想念的吗？

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

Capybara.default_driver = :chrome

class TicTacToeApplicationDriver
  include Capybara::DSL
  include Capybara::RSpecMatchers

  APPLICATION_PORT = 1234

  def initialize
    @application_server = ApplicationServer.new
  end

  def start
    @application_server.start
    visit "http://localhost:#{APPLICATION_PORT}/index.html"
  end

Answer 1

安装chromedriver-helper gem对我有用。

添加

gem 'chromedriver-helper'

到Gemfile中的测试组。

我不知道capybera，但是对于这个错误你可以检查2件事

确保您已将包含文件名的完整路径提供给chromedriver.exe（如果您使用的是linux，则为chromedriver）。如果在Windows中你还需要指定.exe。
如果您使用的是remotewebdriver，而不是更新路径变量，则可以在启动selenium服务器时尝试提供此路径。喜欢

java -jar selenium.jar -Dwebdriver.chrome.driver = fullpathtoexefileincludingfilename

硒:: webdriver的::错误:: WebDriverError：
