使用Capybara + Selenium时禁用JavaScript [英] Disabling JavaScript when using Capybara + Selenium

问题描述

我有一个设计为在禁用JavaScript时仍能正常运行的应用程序，因此我想编写一些涵盖这些情况的规范.

I have an app that's designed to still be functional when JavaScript is disabled, so I wanted to write some specs that covered those cases.

我在Capybara中使用Selenium(Firefox)，并且正在注册一个禁用JavaScript的新驱动程序(通过Selenium的javascript.enabled属性)

I'm using Selenium (Firefox) with Capybara and I'm registering an new driver with JavaScript disabled (via Selenium's javascript.enabled property)

# spec/rails_helper.rb
Capybara.configure do |config|
  config.ignore_hidden_elements = true
  config.default_driver = :selenium
end

Capybara.register_driver :disable_js do |app|
  profile = Selenium::WebDriver::Firefox::Profile.new
  profile["javascript.enabled"] = false
  Capybara::Selenium::Driver.new(app, profile: profile)
end


# spec/features/siging_in_spec.rb
context "JavaScript disabled", driver: :disable_js do
  it "user can still sign in" do
    # ...
    # ...
  end
end

功能规格无法实际禁用JavaScript.在测试期间弹出浏览器窗口并用binding.pry暂停时，我可以肯定地单击我知道需要JavaScript的项目并看到它们正常工作.

The feature specs are failing to actually disable JavaScript. When the browser window pops up during testing and I pause it with binding.pry, I can definitely click around on items I know require JavaScript and see them working.

侧面说明:如果我实际上进入Firefox设置并禁用了JavaScript，则测试通过.因此，它似乎继承了我在浏览器中设置的任何配置，而不实际使用注册驱动程序时指定的配置.

Side note: If I actually go to my Firefox settings and disable JavaScript, the test passes. So it appears it's inheriting whatever configuration I set in my browser, and not actually using the configuration specified when registering the driver.

这是这里的正确方法吗，还是我错过了什么?

Is this the correct approach here, or is there something I missed?

谢谢！

推荐答案

注册驱动程序时无法更改javascript.enabled设置，因为硒将其冻结为true-

It's not possible to change the javascript.enabled setting when registering the driver because selenium freezes it at true - https://github.com/SeleniumHQ/selenium/blob/master/javascript/firefox-driver/webdriver.json#L35 - This was done because of issues with trying to use selenium and firefox with JS disabled https://github.com/SeleniumHQ/selenium/issues/635 - and is unlikely to be changed. Can you just run those specific tests with the rack_test driver? or does it not provide enough functionality?
