Appium [已解决] 真机已安装 app，不要每次都重新安装 apk ，如何执行其他用例时能获取到 driver 属性信息
真机上已经调用如下类方法进行了安装 app
class installApp():
''' 安装app '''
def installAndroidApp(self):
''' 定义安装app函数--安卓 '''
# Returns abs path relative to this file and not cwd
PATH = lambda p: os.path.abspath(os.path.join(os.path.dirname(__file__), p))
desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '4.3'
desired_caps['deviceName'] = 'Android Emulator'
desired_caps['app'] = PATH(r'G:\workspace\src\common\testApp\testApp.apk')
desired_caps['app-Package'] = 'com.android.test'
desired_caps['app-Activity'] = '.test'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
time.sleep(2)
return driver
执行下一个用例的时候，也需要使用 driver 的属性方法，可是不能再调用上面的函数了，因为调用还是会再次安装 app，
请问：如何在不安装 app 的情况下，获取 driver 的属性方法呢？
查询了下资料，说是将
desired_caps['app'] = PATH(r'G:\workspace\src\common\testApp\testApp.apk')
代码注释掉，不过我试了，注释掉上面这行后，依然报错：
#!/usr/bin/env python
# -*- encoding:UTF-8 -*-
from appium import webdriver
import time,os
class getDriverInfo():
''' 获取driver属性信息的类 '''
def androidDriverInfo(self):
''' 定义获取driver属性信息的函数--安卓 '''
# Returns abs path relative to this file and not cwd
#PATH = lambda p: os.path.abspath(os.path.join(os.path.dirname(__file__), p))
desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '4.3'
desired_caps['deviceName'] = 'Android Emulator'
#desired_caps['app'] = PATH(r'G:\workspace\src\common\testApp\testApp.apk')
desired_caps['app-Package'] = 'com.android.test'
desired_caps['app-Activity'] = '.test'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
time.sleep(2)
return driver
if __name__ == '__main__':
driverInfo = getDriverInfo()
app = driverInfo.androidDriverInfo()
print app.contexts()
报错的信息如下：
File "C:\Python27\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 164, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: u"A new session could not be created. (Original error: No app set; either start appium with --app or pass in an 'app' value in desired capabilities, or set androidPackage to launch pre-existing app on device)"
请问大家是如何解决执行测试用例的时候，不要每次都重新安装 apk ，就可以获取 driver 属性信息的？
不是很明白，但是你的意思是不要每次都重新安装 apk 吧？
#1 楼 @lihuazhang 是的，执行下个用例，就不用再需要安装 app，直接使用 driver 属性信息
设置全局 driver，后面 case 都掉它！
在 阿里-sh-lihuazhang C-上海 - 西陆之风 @ 上海-L.T. 的帮助下，终于解决了这个问题
from appium import webdriver
from common.testCaseBase import desired_capabilities
class getDriverInfo():
''' 获取driver属性信息的类 '''
def androidDriverInfo(self):
''' 定义获取driver属性信息的函数--安卓 '''
desired_caps = desired_capabilities.get_desired_capabilities('WeChat_480.apk')
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
print '\n for test',driver,'\n'
return driver
def iOSDriverInfo(self):
''' 定义安装app函数-iOS '''
pass
if __name__ == '__main__':
driverInfo = getDriverInfo()
driver = driverInfo.androidDriverInfo()
如上代码调用的时候，安装 app，如果 app 已经安装了，在不想安装 app 的情况下， 可通过 dos 窗口，通过启动 appium 带上 --no-reset 即可避免执行用例的时候再次安装 app
--no-reset 参数解释 如下：
--no-reset Don't reset app state between sessions (IOS: don't
delete app plist files; Android: don't uninstall app
before new session)
如上解释可通过 dos 窗口执行 appium --no-reset -h 获得
原来的代码也可以使用，总之一句话，app 已安装，在不想每次执行用例都需要再次安装 app 的情况下，启动 appium 带上--no-reset 即可
from common.testCaseBase import desired_capabilities
#6 楼 @strayeagle 你这个模块是自己写的吗？
我根据例子里面的 import desired_capabilities 引入报没有这个模块
import unittest
from appium import webdriver
from appium.common.exceptions import NoSuchContextException
import desired_capabilities
import desired_capabilities
ImportError: No module named desired_capabilities
@mongnet
desired_capabilities 类内容如下：

def get_desired_capabilities(app):

return desired_caps

app = get_desired_capabilities('testBase_2.1.apk')
print app
谢谢 @strayeagle 的回复，我开始还以为这个模块是系统的了
客户端的勾选 no reset
