1 关于appium driver

在之前的文章我们已经完整的安装了appium以及安装过程中相关问题的排查；
我们启动下appium的服务看看：

C:\Users\Administrator>appium
[Appium] Welcome to Appium v2.2.3
[Appium] Appium REST http interface listener started on http://0.0.0.0:4723
[Appium] You can provide the following URLs in your client code to connect to this server:
[Appium]        http://172.16.1.33:4723/
[Appium]        http://127.0.0.1:4723/ (only accessible from the same host)
[Appium]        http://172.23.16.1:4723/
[Appium] No drivers have been installed in C:\Users\Administrator\.appium. Use the "appium driver" command to install the one(s) you want to use.
[Appium] No plugins have been installed. Use the "appium plugin" command to install the one(s) you want to use.

发现提示appium driver没有安装，我们安装下吧；
appium driver测试驱动是分开管理的，默认不会安装任何的测试驱动，通过 appium driver 子命令管理所有的驱动；
官方可用的驱动如下：

C:\Users\Administrator>appium driver list
 - Listing available drivers
✔ Listing available drivers
 - uiautomator2 [not installed]
 - xcuitest [not installed]
 - mac2 [not installed]
 - espresso [not installed]
 - safari [not installed]
 - gecko [not installed]
 - chromium [not installed]

我们的环境是Android，所以需要安装下uiautomator2，其他的按照情况来安装即可。

2 安装appium driver

我们使用以下appium driver install uiautomator2命令安装，但是报错了：

C:\Windows\System32>appium driver install uiautomator2
- Installing 'uiautomator2' using NPM install spec 'appium-uiautomator2-driver'
× Installing 'uiautomator2' using NPM install spec 'appium-uiautomator2-driver'
Error: × Encountered an error when installing package: npm command 'install --save-dev --omit=peer --save-exact --global-style --no-package-lock appium-uiautomator2-driver --json' failed with code 1.

STDOUT:
{
  "error": {
    "code": "ETIMEDOUT",
    "summary": "request to https://registry.npmjs.org/appium-uiautomator2-driver failed, reason: ",
    "detail": "This is a problem related to network connectivity.\nIn most cases you are behind a proxy or have bad network settings.\n\nIf you are behind a proxy, please make sure that the\n'proxy' config is set properly.  See: 'npm help config'"

解决方法是修改npm的镜像源：

# 1.查看npm镜像设置
npm config get registry
# 2.将npm设置为淘宝镜像
npm config set registry https://registry.npm.taobao.org
# 3.再次查看npm镜像设置
npm config get registry

再次安装就成功了：

C:\Windows\System32>appium driver install uiautomator2
 - Installing 'uiautomator2' using NPM install spec 'appium-uiautomator2-driver'
√ Installing 'uiautomator2' using NPM install spec 'appium-uiautomator2-driver'
i Driver uiautomator2@2.34.2 successfully installed
 - automationName: UiAutomator2
 - platformNames: ["Android"]

3 安装Appium Python Client

Python Client针对不同的语言有不同的安装方法，我们使用的python版本的；
关于appium的安装过程的步骤之前已经介绍，也可参考管放文档：Quickstart Intro；
安装Appium Python Client：

pip install Appium-Python-Client

Successfully built Appium-Python-Client
Installing collected packages: sortedcontainers, urllib3, sniffio, pysocks, pycparser, idna, h11, certifi, attrs, wsproto, outcome, cffi, trio, trio-websocket, selenium, Appium-Python-Client
Successfully installed Appium-Python-Client-3.1.0 attrs-23.1.0 certifi-2023.11.17 cffi-1.16.0 h11-0.14.0 idna-3.6 outcome-1.3.0.post0 pycparser-2.21 pysocks-1.7.1 selenium-4.16.0 sniffio-1.3.0 sortedcontainers-2.4.0 trio-0.23.1 trio-websocket-0.11.1 urllib3-2.1.0 wsproto-1.2.0

4 安装测试对象

下载一个支持安卓6.0的扣扣，因为我们模拟器是安卓6.0的；
把下载的扣扣传到模拟器中，本地保存在如下：

F:\monkey_test\QQv5.apk

我们先卸载之前装的：

adb uninstall com.tencent.mobileqqi

F:\monkey_test>adb uninstall com.tencent.mobileqqi
Success

重新安装：

adb install QQv5.apk /data/temp

F:\monkey_test>adb install QQv5.apk /data/temp
Performing Push Install
QQv5.apk: 1 file pushed, 0 skipped. 13.1 MB/s (22506899 bytes in 1.634s)
        pkg: /data/local/tmp/QQv5.apk
        ver: /data/temp
Success

5 获取测试对象信息

以下有三种方式获取应用程序的信息；
我们需要获取的重要信息为：当前app的包名和活动窗口名；
三种方式都可以，选择自己方便的即可。

5.1 使用dumpsys

前提是需要先打开需要测试的app；
我们启动APP后在命令行输入：

adb shell dumpsys | find "mFocusedActivity"

可以看到如下：

 mFocusedActivity: ActivityRecord{54035c5 u0 com.tencent.mobileqqi/com.tencent.mobileqq.activity.InstallActivity t4}

那么重要信息有两个：

# 包名：com.tencent.mobileqqi
# 活动窗口名：com.tencent.mobileqq.activity.LoginActivity

5.2 使用AndroidKiller

AndroidKiller主要是对apk进行反编译操作获取相关信息；
这里不说了，自行搜索吧。

5.3 使用aapt

这个相对来说会方便点，直接找到安装包的路径，使用命令查看即可；
比如我的安装包在本地的F:\monkey_test下：

aapt dump badging QQv5.apk

查看的信息如下：

F:\monkey_test>aapt dump badging QQv5.apk

6 Capabilities详解

6.1 Capabilities介绍

Capabilities是启动appium服务端的参数设置；
关于Capabilities可以参考官方文档：Appium capabilities；
以下重点了解几个Capabilities参数。

6.2 automationName

automationName表示自动化测试引擎，好比测试驱动一样；
可供选择的有Appium、Selendriod、uiautomator2等；
本文及后续都使用的是uiautomator2。

6.3 platformName

platformName表示手机或模拟器使用的操作系统；
一般包括iOS、Android等；
本文使用Android。

6.4 platformVersion

platformVersion表示真机或模拟器操作系统的版本；
本文为Android6.0。

6.5 deviceName

deviceName表示使用的测试设备类型；
可以使用adb devices查看设备类型名称：

C:\Windows\System32>adb devices
List of devices attached
emulator-5554   device

比如我的是emulator-5554。

6.6 app

app表示安装包；
如果指定这个参数就会把指定的app安装到指定的路径。

6.7 newCommandTimeout

newCommandTimeout表示两条Appium命令间的最长时间间隔；
如果超时，会自动退出app。

6.8 noReset

noReset表示不需要在会话前重置应用状态；
默认为false。

6.9 fullReset

fullReset可通过卸载而不清空数据来重置应用状态；
默认为false。

6.10 appPackage和appActivity

启动待测试app的appPackage和appActivity；
appPackage是app的包名；
appActivity是app的活动窗口名；
这两个参数的获取已经在第五章节说明了。

还有几个参数，这个不一一说明了，直接看官方文档即可。

7 官方示例

以下这个是官方的一个示例，是python版本的；

import unittest
from appium import webdriver
from appium.options.android import UiAutomator2Options
from appium.webdriver.common.appiumby import AppiumBy

capabilities = dict(
    platformName='Android',
    automationName='uiautomator2',
    deviceName='Android',
    appPackage='com.android.settings',
    appActivity='.Settings',
    language='en',
    locale='US'
)

appium_server_url = 'http://localhost:4723'

class TestAppium(unittest.TestCase):
    def setUp(self) -> None:
        self.driver = webdriver.Remote(appium_server_url, options=UiAutomator2Options().load_capabilities(capabilities))

    def tearDown(self) -> None:
        if self.driver:
            self.driver.quit()

    def test_find_battery(self) -> None:
        el = self.driver.find_element(by=AppiumBy.XPATH, value='//*[@text="Battery"]')
        el.click()

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

8 测试示例

这里我们写一个我们自己的测试示例；
之前我们已经安装了测试对象扣扣，且已经获取到了它的相关信息；
我们启动appium服务，直接在命令行输入appium即可：
设计如下脚本：


# -*- coding:utf-8 -*-
# 作者：虫无涯
# 日期：2023/12/12
# 文件名称：test_qq.py
# 作用：appium启动一个应用程序
# 联系：VX(NoamaNelson)
# 博客：https://blog.csdn.net/NoamaNelson

from appium import webdriver
from appium.options.android import UiAutomator2Options
from appium.webdriver.common.appiumby import AppiumBy
import time

capabilities = dict(
    platformName='Android',
    automationName='uiautomator2',
    deviceName='emulator-5554',
    appPackage='com.tencent.mobileqqi',
    appActivity='com.tencent.mobileqq.activity.SplashActivity',
    language='en',
    locale='US'
)


print("start....")
# 创建driver对象
appium_server_url = 'http://localhost:4723'
driver = webdriver.Remote(appium_server_url, options=UiAutomator2Options().load_capabilities(capabilities))

# 启动应用程
print(driver.capabilities)
# driver.launch_app()

time.sleep(1)
print("已经连接到模拟器了~")

driver.quit()

执行脚本：

D:\Python37\python.exe F:/python_study/appium_test/test_qq.py
start....
{'platformName': 'Android', 
'automationName': 'uiautomator2', 
'deviceName': 'emulator-5554',

'language': 'en', 
'locale': 'US', 
'platform': 'LINUX',

'deviceApiLevel': 23, 'platformVersion': '6.0', 'deviceManufacturer': 'unknown', 'deviceModel': 'sdk_phone_armv7', 'deviceScreenSize': '768x1280', 'deviceScreenDensity': 320}
已经连接到模拟器了~

这时候appium的服务端也给出了启动信息：

[AndroidUiautomator2Driver@455c (f190abfc)] Proxying [DELETE /] to [DELETE http://127.0.0.1:8200/session/f9cc13f6-4c4e-4ab5-a2eb-8dfb44f05100] with no body

[Instrumentation] .
[Instrumentation] Time: 74.226
[Instrumentation]
[Instrumentation] OK (1 test)

同时模拟器中也打开了扣扣应用程序。

9 启动问题排查

9.1 urllib3 v2.0 only supports OpenSSL 1.1.1+

如果启动过程出现这个错误：

DEPRECATION: celery 5.0.5 has a non-standard dependency specifier pytz>dev. pip 24.0 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of celery or contact the author to suggest that they release a version with a conforming dependency specifiers. Discussion can be found at https://github.com/pypa/pip/issues/12063

则说明Python 环境使用的是 OpenSSL 1.1.0h，而 urllib3 v2.0 需要使用 OpenSSL 1.1.1；
解决方法是：

# 要么升级 OpenSSL 到 1.1.1 或更高版本。
# 要么降级 urllib3 到 v1.x 版本，可以通过命令 pip install urllib3==1.* 来实现。

本文使用降级 urllib3来解决的，但是可能会导致其他依赖包问题。

pip install urllib3==1.26.15

9.2 UnknownError: An unknown server-side error occurred

如果出现以下错误：

UnknownError: An unknown server-side error occurred while processing the command. Original error: Error executing adbExec. Original error: 'Command 'D:\\android-sdk-windows\\platform-tools\\adb.exe -P 5037 -s emulator-5554 shell pm install -r /data/local/tmp/appium_cache/72200c7819db015d5717d05800401c19b35842d5.apk' timed out after 20000ms'. Try to increase the 20000ms adb execution timeout represented by 'uiautomator2ServerInstallTimeout' capability

说明adb安装appium服务的时候报错；
解决方法是先卸载：

adb uninstall /data/local/tmp/appium_cache/72200c7819db015d5717d05800401c19b35842d5.apk

再原样使用命令安装即可：

adb  -P 5037 -s emulator-5554 shell pm install -r /data/local/tmp/appium_cache/72200c7819db015d5717d05800401c19b35842d5.apk
