【Mac + Python3.6 + facebook-wda】之IOS自动化（二）：安装facebook-wda库并编写简易自动化测试脚本，,上一篇介绍完如何安装

上一篇介绍完如何安装WDA，接下来开始正式安装开发库并编写自动化脚本。

目录：

一、安装facebook-wda库

二、通过WEditor定位元素

三、附录：学习资料

一、安装facebook-wda库

运行命令行安装：

pip install --pre facebook-wda

或者使用pycharm中，Preferences->Project->Project Interpreter->【+】(加号), 搜索：facebook-wda，并安装

举个栗子，页面元素定位，如下图，class、name一一展示：

通过“ideviceinstaller -l”或者其他工具查找到APP软件的bundleId

$ ideviceinstaller -lTotal: 5 appscom.ysr.scancode - 二维码扫描器 3com.apple.test.WebDriverAgentRunner-Runner - WebDriverAgentRunner-Runner 1com.sogou.sogouinput - 搜狗输入法 142709com.netease.cloudmusic - 网易云音乐 1044com.leqimea.recorderAudio - PP助手 10000

上代码：

#!/usr/bin/env python# -*- coding: utf-8 -*-# @Time    : 2018/10/16 11:42# @Author  : zc# @File    : test.pyimport unittestimport wdawda.DEBUG = False # default Falsewda.HTTP_TIMEOUT = 10.0 # default 60.0 secondsbundle_id = "com.chen.CityMineSafetyOne"  （通过上面获得）c = wda.Client(‘http://localhost:8100‘)# 启动应用s = c.session(bundle_id)class Test_safety(unittest.TestCase):    def setUp(self):        print("=======start!=======")        pass    def tearDown(self):        print("=======stop!=======")        pass    def test1(self):　　　　　# class、name定位参考网易图所示，这里只是举个栗子，并不是网易代码        s(name=‘home btn newtask‘,className=‘Button‘).tap()if __name__ == ‘__main__‘:    unittest.main()

运行成功！！！！

二、通过WEditor定位元素　　　　　　 返回目录

之前做uiautomator2-Android自动化时，用到了这个进行定位元素，facebook-wda-IOS自动化也可以通过这个进行定位元素。

首先，启动weditor

python -m weditor

有时候会报错：OSError: [Errno 48] Address already in use

提示您地址已经被占用，所以我们可以查看weditor的17310端口，看看哪些软件占用了此端口：

# 查看端口使用情况lsof -i tcp:17310COMMAND    PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAMEGoogle     396 zhan  156u  IPv6 0x9b9eee3e3dae5dfb      0t0  TCP localhost:58732->localhost:17310 (ESTABLISHED)python3.6 8244 zhan    4u  IPv6 0x9b9eee3e34507f3b      0t0  TCP *:17310 (LISTEN)# 其中谷歌和py3.6占用了端口，选择杀死进程kill 396kill 8244

接着再启动weditor，发现还是报错：

ModuleNotFoundError: No module named ‘atx‘

需要安装atx：

pip install atx==1.1.2.dev18

在安装cv2，作用是读取图像相关的：

 pip install opencv-python

再次运行weditor，又发生错误：

from atx import ioskit
File "/Users/zhangc/.pyenv/versions/3.6.1/lib/python3.6/site-packages/atx/ioskit.py", line 199
print dev.screenshot(‘i.png‘)
^
SyntaxError: invalid syntax

语法错误，经过大神调试得知原来是，atx版本问题，升级atx版本。

# 查看pip下各个库的版本pip list# 得知atx (1.1.2.dev18)pip (9.0.1)# 升级pippip install --upgrade pip# 升级atxpip install -U atx# 再查看pip下各个库版本    Package       Version    --------------- -----------       atx           1.2.0      pip           18.1  # 最后再运行weditorpython -m weditor

weditor终于启动成功！！！！！

浏览器自动打开weditor，选择IOS，输入地址：http://localhost:8100，点击【Connect】连接，出现小绿叶??表示连接成功，再点击蓝色按钮【Reload】刷新如下：

至此facebook-wda安装以及元素定位讲解到此为止。
