Question

要实现一些简单操作（如更改运行Capybara + webdriver的浏览器窗口）似乎非常困难

我正在针对外部网站进行测试。我想要的是最大化浏览器窗口。我在网络上发现了许多提示，但似乎无济于事。要复制的最少代码是：

require 'capybara'
require 'selenium-webdriver'

session = Capybara::Session.new(:selenium)
window = Capybara.current_session.current_window
window.resize_to(1920,1080)
sleep(10)

结果是

Traceback (most recent call last):
        5: from C:/src/Ruby/Capybara/minimal.rb:5:in `<main>'
        4: from C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/capybara-3.9.0/lib/capybara/session.rb:426:in `current_window'

有什么想法吗？

您正在创建一个会话，但是随后在另一个会话的窗口上调用了resize。另一个会话是使用默认驱动程序（机架测试）自动生成的会话，该驱动程序根本不支持Windows。如果要通过手动创建的会话执行此操作，则只需

session = Capybara::Session.new(:selenium)
session.current_window.resize_to(1920,1080)
