Selenium :: WebDriver :: Error :: WebDriverError：

Question

我正在尝试对JavaScript代码进行一些验收测试。但是，当我尝试将Capybara与Selenium结合使用时，我一直得到以下信息：

>> 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)>'

下面的代码是应该启动驱动程序的代码。我从http://code.google.com/p/chromedriver/downloads/list下载了适当的文件，然后通过运行PATH
= $ PATH：/ directory / where / chromedriver /
exists并导出PATH将其放在“路径”中，然后使它可执行，但仍然出现错误。我有什么想念的吗？

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

我不知道capybera，但是对于这个错误，您可以检查2件事

1. 确保您已将完整路径（包括文件名）提供给chromedriver.exe（如果您在Linux中，则为chromedriver）。如果在Windows中，则还需要指定.exe。

2. 如果使用的是remotewebdriver，而不是更新path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 =完整路径到exe文件包括文件名
