从 selenium-webdriver 收到不需要的消息，如何隐藏它？

Question

我正在使用 selenium-webdriver 自动执行与 Web 浏览器相关的任务。但是当我执行以下操作时，得到了如下的 messgaes 块。为什么会这样，你能告诉我吗？以及如何压制它的任何想法？

irb(main):001:0> require "selenium-webdriver"
=> true
irb(main):002:0> driver=Selenium::WebDriver.for :firefox

Answer 1

您的 Firefox 配置文件正在启动时检查附加组件。当我在 Windows 中开发基于 Ruby 的 Selenium 测试时，我经常收到此消息。切换到 Mac OS X 然后再切换到 Ubuntu 实际上似乎为我解决了这个问题，但由于这有点极端，你可以做一个解决方法。

首先，您需要在 Firefox 中设置一个在启动时不检查附加组件的新配置文件。这是您需要在该配置文件上设置的选项的一个主题：link。以下是 Mozilla 关于如何使用 Firefox 配置文件管理器的参考，以备不时之需：link

然后在你的 Ruby 代码中，你有这样的东西：

driver = Selenium::WebDriver.for :firefox

您需要添加一个选项来告诉 Webdriver 要使用哪个配置文件。它最终会变成这样：

driver = Selenium::WebDriver.for :firefox, :profile => "selenium_testing"

（只需将“selenium_testing”替换为您为新配置文件命名的任何内容。）

然后你应该能够启动 Firefox 而没有那些恼人的警告。

我通过将 Firefox 升级到旧版本（与 Selenium-WebDriver 配合良好）解决了这个问题。就我而言，我不得不降级回Firefox 18，而这个版本与Selenium 2.27一起工作
