水豚：如何改变 window 大小？

Question

似乎很难实现像更改浏览器这样简单的事情window 运行 Capybara + webdriver

我正在针对外部网站进行测试。我想要的是最大化我的浏览器window。我在网上找到了很多提示，但似乎没有任何效果。要重现的最少代码是：

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？

Answer 1

您正在创建一个会话，但随后从另一个会话对 window 调用调整大小。另一个会话是使用默认驱动程序 (rack-test) 自动生成的会话，它根本不支持 windows。如果你想用你手动创建的会话来做到这一点，它只是

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