篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Mac + Python3.6 + facebook-wda之IOS自动化：安装facebook-wda库并编写简易自动化测试脚本相关的知识，希望对你有一定的参考价值。
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
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 -l Total: 5 apps com.ysr.scancode - 二维码扫描器 3 com.apple.test.WebDriverAgentRunner-Runner - WebDriverAgentRunner-Runner 1 com.sogou.sogouinput - 搜狗输入法 142709 com.netease.cloudmusic - 网易云音乐 1044 com.leqimea.recorderAudio - PP助手 10000
但是，会一直报错Could not connect to lockdownd. Exiting.
痛苦了大半天，终于找到了解决办法：
参考：《IOS 执行ideviceinstaller -l ,结果报错Could not connect to lockdownd. Exiting.》
上代码：
#!/usr/bin/env python # -*- coding: utf-8 -*- # @Time : 2018/10/16 11:42 # @Author : zc # @File : test.py import unittest import wda wda.DEBUG = False # default False wda.HTTP_TIMEOUT = 10.0 # default 60.0 seconds bundle_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，非常方便，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:17310 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME Google 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 396 kill 8244
接着再启动weditor，发现还是报错：
ModuleNotFoundError: No module named \'atx\'
需要安装atx：

You should consider upgrading via the \'pip install --upgrade pip\' command.
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pip pip install --upgrade pip # 升级atx pip 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weditor python -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
