Ruby Selenium - 警告：driver_path 已弃用

Question

使用 Ruby selenium-webdriver 3.142.6

\n\n

我的测试有效，但在运行开始时它显示警告

\n\n

WARN Selenium [DEPRECATION] :driver_path is deprecated. Use :service with an instance of Selenium::WebDriver::Service instead.\n

\n\n

根据 Ruby 文档，Selenium::WebDriver::Service 是一个私有 API。

\n\n

在网上搜索与该警告相关的文章，参考了 Capybara、RoR 和 chromedriver-help，但我\xe2\x80\x99m 都没有使用这些内容。我尝试过“gem install webdrivers”，但失败了。

\n\n

关于采取的路径有什么建议：忽略弃用消息，或使用私有 Service 类（如果是的话如何使用它），或尝试用 webdrivers 替换 selenium-webdriver，或其他什么？

这是成功创建 Selenium 驱动程序的代码，但出现警告

\n\n

require "selenium-webdriver"\nrequire "test/unit"\nrequire "byebug"\n\n...\n\nclass GoogleTest < Test::Unit::TestCase\n\n  def setup\n\n    case $browser_arg\n    when \'chrome\'\n        browser = :chrome\n        driver_path = \'/selenium_browser_drivers/chromedriver\'\n    when \'firefox\'\n        browser = :firefox\n        driver_path = \'/selenium_browser_drivers/geckodriver\'\n    else\n          raise ArgumentError.new("Unexpected browser argument \'#{$browser_arg}\'") \n          exit      \n    end\n      @se = Selenium::WebDriver.for browser, :driver_path => driver_path\n\n  end\n...\n

即使在实例化驱动程序变量之前，您也可以通过显式分配 driver_path 变量来避免此错误。看下面的代码

require 'selenium-webdriver'
Selenium::WebDriver::Chrome::Service.driver_path = "C:/Ruby26/chromedriver.exe"
driver = Selenium::WebDriver.for :chrome
driver.manage.timeouts.implicit_wait = 10
driver.navigate.to("https://www.google.com/")
driver.find_element(name: 'q').send_keys 'raja'

此代码不会发出该警告。Selenium::WebDriver::Chrome::Service.driver_path = "C:/Ruby26/chromedriver.exe"因为我在创建驱动器之前分配了该值。
