如何设置Rails系统测试的膨化 [英] How to setup puffing-billy to Rails System Test

问题描述

我正在尝试设置puff-billy以与Rails System Test一起使用.由于它为此使用Capybara，因此我在这里尝试了所有记录在案的Capybara解决方案，但似乎没有正确设置它.

I'm trying to setup puffing-billy to work with Rails System Test. Since it uses Capybara for that, I tried all the documented Capybara solutions here, but didn't seem to get it correctly setup.

系统测试为配置文件生成一个application_system_test_case.rb.看起来是这样的:

System Test generates an application_system_test_case.rb for config stuff. Here's how it looks like:

require "test_helper"
require 'billy'

class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
  driven_by :selenium, using: :headless_chrome, screen_size: [1400, 1400]

  Capybara.javascript_driver = :selenium_chrome_billy
  Capybara.current_driver = Capybara.javascript_driver

  WebMock.allow_net_connect!
end

实际的测试文件如下:

require "application_system_test_case"

class PromotionsTest < ApplicationSystemTestCase
  include ApplicationHelper

  make_my_diffs_pretty!
  Capybara.default_max_wait_time = 3
  Capybara.configure do |config|
    config.app_host = "http://dev.myapp.com"
  end

  test 'Stub test' do
    proxy.stub('http://www.google.com/').and_return(:text => "I'm not Google!")

    visit 'http://www.google.com/'
  end
end

但是当我运行测试时: NameError: undefined local variable or method 'proxy' for #<PromotionsTest:0x00007fd357450c90>.

But then when I run the tests: NameError: undefined local variable or method 'proxy' for #<PromotionsTest:0x00007fd357450c90>.

我在做什么错了?

推荐答案

IIRC puffing-billy不会安装系统测试的帮助程序，因此您需要通过Billy名称空间访问代理

IIRC puffing-billy doesn't install helpers for system tests so you'll need to access the proxy via the Billy namespace

Billy.proxy.stub(...)

此外，系统测试会覆盖javascript_driver', current_driver , etc so you need to specify the driver you want to use via driven_by`

Also, system tests override javascript_driver',current_driver, etc so you need to specify the driver you want to use viadriven_by`

driven_by :selenium, using: :selenium_chrome_billy

注意:我不在我的主计算机上，所以这一切都不在我的脑海，也许不是100％正确，但应该使您走上正确的道路.

Note: I'm away from my main computer so this is all off the top of my head and may not be 100% correct but should put you on the right path.
