配置Capybara以使用Marionette WebDriver for Firefox [英] Configure Capybara to use Marionette WebDriver for Firefox

问题描述

随着木偶取代了FirefoxDriver，我需要配置测试以运行它。
我已经下载了二进制文件，但似乎无法将Capybara驱动程序注册配置为实际使用木偶。

With Marionette replacing FirefoxDriver, I need to configure my tests to run it. I've downloaded the binary but I can't seem to get my Capybara driver registration configured to actually use Marionette.

Capybara.register_driver :selenium_firefox do |app|
  capabilities = Selenium::WebDriver::Remote::Capabilities.firefox
  capabilities["firefox_binary"] = 'path/to/marionette/renamed/to/wires'
  Capybara::Selenium::Driver.new(app, browser: :firefox, desired_capabilities: capabilities)
end

但是当我开始测试时，就像在没有木偶的情况下尝试一样，我只是得到FF的初始页面。

When I start a test though, I just get the initial page of FF just like I would trying to run it without marionette.

推荐答案

牵线木偶被传递给Driver.new的选项-而不是期望的能力

marionette is passed an option to Driver.new - not to desired_capabilities

Capybara.register_driver :selenium_firefox do |app|
  Capybara::Selenium::Driver.new(app, browser: :firefox, marionette: true)
end

还需要您下载geckodriver，将其放在路径中，并将其重命名为wire

It also requires you to have downloaded geckodriver, put it in your path and renamed it to wires

这些配置步骤的完整说明，其中包括木偶最新的可执行文件下载链接可在此处找到

注意：水豚还不支持木偶，一些问题已在水豚中修复，一些是selenium-webdriver中的错误，而另一些只是一般性-诸如此类的事情只是停止从选择元素中选择选项-没有引发错误，只是停止工作。我认为它还没有准备好在现实世界中使用。

Note: Capybara does not yet support marionette, some things are being fixed in capybara, some are bugs in selenium-webdriver, and others are just general flakiness of it - things like it just stops selecting options from select elements - no errors thrown, just stops working. I don't think its ready for real world use yet.
