【Mac + Python3.6 + ATX基於facebook-wda】之IOS自動化（二）：安裝facebook-wda庫並編寫簡易自動化測試腳本

上一篇介紹完如何安裝WDA，接下來開始正式安裝開發庫並編寫自動化腳本。

目錄： 

• 1、安裝facebook-wda庫

• 2、經過WEditor定位元素

• 3、附錄：學習資料

 

 

1、安裝facebook-wda庫

運行命令行安裝：

pip install --pre facebook-wda

或者使用pycharm中，Preferences->Project->Project Interpreter->【+】(加號), 搜索：facebook-wda，並安裝

 

舉個栗子，頁面元素定位，以下圖，class、name一一展現：

 

 

經過「ideviceinstaller -l 」或者其餘工具查找到APP軟件的bundleId

$ ideviceinstaller -l
Total: 5 apps
com.ysr.scancode - 二維碼掃描器 3
com.apple.test.WebDriverAgentRunner-Runner - WebDriverAgentRunner-Runner 1
com.sogou.sogouinput - 搜狗輸入法 142709
com.netease.cloudmusic - 網易雲音樂 1044
com.leqimea.recorderAudio - PP助手 10000

 可是，會一直報錯Could not connect to lockdownd. Exiting.

痛苦了大半天，終於找到了解決辦法：

參考：《IOS 執行ideviceinstaller -l ,結果報錯Could not connect to lockdownd. Exiting.》

上代碼：

#!/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"  （經過上面得到）
c = wda.Client('http://localhost:8100')

# 啓動應用
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定位參考網易圖所示，這裏只是舉個栗子，並非網易代碼
        s(name='home btn newtask',className='Button').tap()

if __name__ == '__main__':
    unittest.main()

 

運行成功！！！！

2、經過WEditor定位元素　　　　　　    返回目錄

以前作uiautomator2-Android自動化時，用到了這個進行定位元素，很是方便，facebook-wda-IOS自動化也能夠經過這個進行定位元素。

首先，啓動weditor

python -m weditor

有時候會報錯：OSError: [Errno 48] Address already in use

提示您地址已經被佔用，因此咱們能夠查看weditor的17310端口，看看哪些軟件佔用了此端口：

# 查看端口使用狀況
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佔用了端口，選擇殺死進程
kill 396
kill 8244

接着再啓動weditor，發現仍是報錯：

ModuleNotFoundError: No module named 'atx'

須要安裝atx：

You are using pip version 9.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

在安裝cv2，做用是讀取圖像相關的：

 pip install opencv-python

 

再次運行weditor，又發生錯誤：

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

語法錯誤，通過大神調試得知原來是，atx版本問題，升級atx版本。

# 查看pip下各個庫的版本
pip list

# 得知
atx (1.1.2.dev18)
pip (9.0.1)

# 升級pip
pip install --upgrade pip

# 升級atx
pip install -U atx

# 再查看pip下各個庫版本
    Package       Version    
--------------- -----------  
     atx           1.2.0 
     pip           18.1  

# 最後再運行weditor
python -m weditor

 

weditor終於啓動成功！！！！！

瀏覽器自動打開weditor，選擇IOS，輸入地址：http://localhost:8100，點擊【Connect】鏈接，出現小綠葉🍀表示鏈接成功，再點擊藍色按鈕【Reload】刷新以下：

 

 至此facebook-wda安裝以及元素定位講解到此爲止。
