Question

我使用Capybara和WebMock以及代理（Sinatra）来测试远程应用程序。我没有存根请求，而是使用WebMock断言请求。我已将代理分配给capybara.app并添加到Chrome驱动程序中，以便将请求转发给代理。

我的问题是，有时候我有待处理的请求会引发以下错误：

Failure/Error: raise "Requests did not finish in 60 seconds"

我想知道如何禁用此错误？另外，如何更改60的硬编码超时（无论如何都会阻止测试的继续）

Timeout.timeout(60) { sleep(0.01) while @middleware.pending_requests? }

capybara.rb：

require 'capybara/rspec'
require 'capybara'
require 'capybara/dsl'
require_relative 'sinatra_proxy'
require 'selenium/webdriver'
require 'selenium/webdriver/remote/http/curb' if !isWindows

Capybara.server_port = 9980

Capybara.register_driver :selenium_chrome do |app|
  http_client = isWindows ? nil : Selenium::WebDriver::Remote::Http::Curb.new
  options = {
      http_client: http_client,
      browser: :chrome,

      switches: [
          "--proxy-server=0.0.0.0:9980",
          "--disable-web-security",
          '--user-agent="Chrome under Selenium for Capybara"',
          "--start-maximized",
          '--no-sandbox',
      ]
  }
  Capybara::Selenium::Driver.new app, options
end

Capybara.default_driver = :selenium_chrome
Capybara.app = SinatraProxy.new
Capybara.server_host = '0.0.0.0'
Capybara.default_max_wait_time = 8

Sinatra代理：

require "sinatra"
require 'net/http'
require 'json'

file = File.read 'config.json'
config_json = JSON.parse(file)
HOST = 'remote_app'
PORT = '80'
HEADERS_NOT_TO_PROXY = %w(transfer-encoding)

class SinatraProxy < Sinatra::Base
    # configure :development do
    #   register Sinatra::Reloader
    # end

    def request_headers
        request.env.select {|k,v| k.start_with? 'HTTP_'}
                .collect {|pair| [pair[0].sub(/^HTTP_/, ''), pair[1]]}
                .to_h # Ruby 2.1
                .merge('CONTENT-TYPE' => request.env['CONTENT_TYPE'] || 'application/json')
    end

    proxy = lambda do
        # puts "REQUEST HEADERS #{request_headers}"

        uri = URI.parse(request.url)
        http = Net::HTTP.new(HOST, PORT)
        response = http.send_request(
                request.request_method.upcase,
                uri.request_uri,
                request.body.read,
                request_headers)

        response_headers = {}
        response.to_hash.each{|k,v| response_headers[k]=v.join unless HEADERS_NOT_TO_PROXY.include?(k) }

        status response.code
        headers response_headers
        headers 'Access-Control-Allow-Origin' => '*'
        # puts "RESPONSE HEADERS #{response_headers}, BODY: #{response.body}"
        body response.body
    end

    get '/*', &proxy
    post '/*', &proxy
    patch '/*', &proxy
    put '/*', &proxy
    delete '/*', &proxy

    options "*" do
        headers 'Access-Control-Allow-Origin' => '*',
                        'Access-Control-Allow-Methods' => 'HEAD,GET,PUT,DELETE,OPTIONS'
        halt 200
    end
end

您无法在重置期间更改等待的超时，但是您不应该为您的代理应用设置Capybara.app。 Capybara.app适用于您的AUT（正在测试的应用程序），其中任何在被告知退出后挂起超过60秒的请求肯定是错误的。由于您的代理不是您的AUT，只需单独运行它并告诉Capybara不要运行服务器/应用程序。

Capybara.run_server = false

Thread.new do  
  Rack::Handler::Puma.run(SinatraProxy.new, Host: '0.0.0.0', Port: 9980) # You might need/want other options here or to use thin/webrick/etc 
end
