如何使用远程硒扩展水豚超时

问题描述

我创建了一个SystemSpec来使用远程硒截屏。该测试包含三个步骤。

创建100,000条记录
访问/ book
拍摄一张屏幕截图

在第3步中，我总是检测到超时，并且总是在一些记录中获取屏幕截图。

require 'rails_helper'

RSpec.describe 'Books',type: :system do
  before do
    100_000.times do
      Book.create!(price: 200)
    end
  end

  it 'scenario #1' do
    visit books_path
    take_screenshot # always timed out !!!
  end
end

Failures:

  1) Books scenario #1
     Failure/Error: visit books_path
     
     Net::ReadTimeout:
       Net::ReadTimeout with #<Tcpsocket:(closed)>

我想延长时间以等待屏幕截图完成。怎么做？？

我尝试更新等待时间。首先，我添加了Capybara.default_max_wait_time = 1200，但没有任何意义。其次，我有如下更新水豚的配置，但它也是输出错误消息，例如unkNown option: {:"enable-features"=>"NetworkService,NetworkServiceInProcess"}

require 'capybara/rspec'

RSpec.configure do |config|
  config.before(:each,type: :system) do
    driven_by :selenium,using: :headless_chrome,options: {
      browser: :remote,'enable-features': 'NetworkService,NetworkServiceInProcess',url: ENV.fetch("SELENIUM_DRIVER_URL"),desired_capabilities: :chrome
    }
    Capybara.server_host = 'web'
    Capybara.app_host='http://web'
  end
end

更新

我像这样更新books_spec.rb以等待渲染，但是结果是“超时”。渲染/ books大约需要16秒。输出“超时”不会太长。

require 'rails_helper'

RSpec.describe 'Books',type: :system do
  before do
    100_000.times do
      Book.create!(price: 200)
    end
  end

  it 'scenario #1' do
    visit books_path
    expect(page).to have_content('New Book')
    take_screenshot
  end
end
