ruby - Appium + Watir + Chromedriver 处理命令时出现未知的服务器端错误

问题描述

我的项目中有以下代码：

功能/env.rb

require 'rubygems'
require 'rspec'
require 'watir'
require 'webdrivers'
require 'yaml'
require 'fileutils'
require './features/Util/Tools.rb'
require 'json'
require 'watir-scroll'
require "mini_magick"
require 'watir-screenshot-stitch'
require 'appium_lib'
require 'selenium-webdriver'

    server_url = 'http://localhost:4723/wd/hub/'

    capabilities =
    {
    platformName: 'Android',
    platformVersion: '7.0',
    deviceName: 'Android Emulator',
    browserName: 'Chrome'
    }

    $navegador = "chrome_dev_mobile"

    $appium_driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)

    $driver Watir::Browser.new $appium_driver

当我运行我的黄瓜功能时，我收到了这个错误：

And Verificar Portal abierto                   # features/step_definitions/Home/Home_Chile/SD1_Home.rb:16

  features/features/Pruebas_Mobile/CL_Mobile.feature:4:in `And Verificar Portal abierto'

那是./features/pages/Home/Home_Page/P1_HomePage.rb:20里面的代码

def verificar_pagina
      @caja_busqueda.wait_until_present
      if @caja_busqueda.present?
        puts "Portal abierto satisfactoriamente con: " + $navegador
      end
  end

移动版chrome打开我的网址，然后出现这个错误。请我尝试一切，我接受建议

我手动设置了appium chromedriver路径并使用它。查看 appium 日志会显示以下内容以及更多详细信息：

解决方案

我以这种方式证明：

require 'watir'
require 'selenium-webdriver'

    server_url = 'http://localhost:4723/wd/hub/'

    capabilities =
    {
    platformName: 'Android',
    platformVersion: '7.0',
    deviceName: 'Android Emulator',
    browserName: 'chrome'
    }


    $driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)

    $driver.get "http://www.google.com"

有用！！！

但是当一个看跌期权

$appium_driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)
$driver = Watir::Browser.new $appium_driver

然后在我尝试与定位器交互时显示错误。

也许这是 watir 与 selenium 和 appium 之间的冲突，我不知道。很遗憾，因为我有一个关于 Watir 的整个项目制作成网页，我不能在移动设备测试上重用所有这些代码。

任何建议都将被接受
