每次我使用python在appium中运行测试时如何防止应用程序重新安装答案

【问题标题】：How to prevent app from re-installing each time when I run tests in appium using python每次我使用python在appium中运行测试时如何防止应用程序重新安装
【发布时间】：2016-07-11 16:25:48
【问题描述】：

我为 Android 应用程序的自动化测试编写了 python 测试套件。这套衣服有多个测试用例。我现在只放了2个。

问题在于，在每个测试用例之后，应用程序都会被卸载，然后重新安装。每个测试用例都会发生这种情况。卸载并重新安装需要花费很多时间..

我使用的Appium版本是1.5.0

我尝试过使用：

desired_caps['noReset'] = 'true'

desired_caps['fullReset'] = 'false'

和

appium --no-reset

但是，没有用..

这是我的python代码文件playpause.py：

class MaverickAndroidTests(unittest.TestCase):

    def setUp(self):
        "Setup for the test"
        desired_caps = {}
        desired_caps['browserName']=''
        desired_caps['platformName'] = 'Android'
        desired_caps['platformVersion'] = '4.4.2'       
        desired_caps['deviceName'] = 'karthikphone1'
        desired_caps['app'] = '/home/karthik/appiumworkspace/tests/app-debug (8).apk'
        desired_caps['noReset'] = 'true'
        desired_caps['fullReset'] = 'false'
        desired_caps['appPackage'] = 'com.prueba.maverick'
        desired_caps['app-activity'] = '.SplashActivity' 
        desired_caps['app-wait-activity'] = '.CommonViewActivity' 
        self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

    def test_on_play_and_pause(self):   
        self.driver.implicitly_wait(15) # seconds
        print(" ")
            element = WebDriverWait(self.driver, 15).until(EC.presence_of_element_located((By.ID, "tabs")))
        self.assertIsNotNone(element)
        element = WebDriverWait(self.driver, 15).until(EC.presence_of_element_located((By.XPATH, "//android.widget.TextView[@text='RECORD']")))
        self.assertIsNotNone(element)
        print element.text
        element.click() #click on RECORD tab
        element = WebDriverWait(self.driver, 30).until(EC.presence_of_element_located((By.ID, "Btn_Rec")))
        self.assertEqual("PRESS TO RECORD", element.text, "not equal")
        print(element.text)
        element.click()
        time.sleep(4)   
        element = WebDriverWait(self.driver, 10).until(EC.presence_of_element_located((By.ID, "Btn_Rec")))
        self.assertEqual("RECORDING... PRESS TO STOP", element.text, "not equal")
        print(element.text)
        element.click()
        time.sleep(1)
        element = WebDriverWait(self.driver, 30).until(EC.presence_of_element_located((By.ID, "Btn_Save")))
        element.click()
        time.sleep(2)
        print(' ')
        print('AUDIO RECORDED SUCCESSFULLY')    
        print(" ")

    def test_indefinite_times_Pausing_and_Unpausing(self):  
        element = WebDriverWait(self.driver, 30).until(EC.presence_of_element_located((By.ID, "Btn_Rec")))
        self.assertEqual("PRESS TO RECORD", element.text, "not equal")
        print(element.text)
        element.click()
        time.sleep(4)   
        element = WebDriverWait(self.driver, 10).until(EC.presence_of_element_located((By.ID, "Btn_Rec")))
        self.assertEqual("RECORDING... PRESS TO STOP", element.text, "not equal")
        print(element.text)
        element.click()
        time.sleep(1)
        element = WebDriverWait(self.driver, 30).until(EC.presence_of_element_located((By.ID, "Btn_Rec")))
        self.assertEqual("PAUSED... PRESS TO RESUME", element.text, "not equal")
        print(element.text)
        element.click()
        time.sleep(4)


    def tearDown(self):
        "Tear down the test"
    #   self.driver.quit()

if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(MaverickAndroidTests)
    unittest.TextTestRunner(verbosity=2).run(suite)

我已经在拆卸函数中注释了退出语句..

请帮帮我..

【问题讨论】：

标签： android python automation appium test-suite

【解决方案1】：

在 appium 1.5 版中，他们更改了命令行参数，您现在应该这样使用它：

appium --default-capabilities '{"noReset":true}'

更多信息请访问 appium 网站： http://appium.io/docs/en/writing-running-appium/default-capabilities-arg/

【讨论】：

我什至在设置函数中声明了noReset = true.. 那不行吗？？

【解决方案2】：

在每个测试用例之前注释这个，

> def tearDown(self):
>         "Tear down the test"
>         self.driver.quit()

并且仅在最后一个测试用例结束时运行它。因为这会杀死 appium 会话

【讨论】：

test_on_play_and_pause(self)' and test_indefinite_times_Pausing_and_Unpausing(self)' 是 2 个测试用例。对吗？！
def tearDown(self) 在我的测试服中只使用了一次。在测试服的末尾只有一个teardown 方法..
它会卸载应用程序，如果它之前存在的话。在测试test_on_play_and_pause(self) 时它会安装应用程序，在测试后它会卸载应用程序。再次安装并测试 test_indefinite_times_Pausing_and_Unpausing(self) 。在此之后测试结束..
我现在没有笔记本..我会在星期二拿回来..我会按照你说的去做，看看会发生什么..还是谢谢..:)
如果我删除退出功能代码，我会收到错误，说WebDriverException: Message: A new session could not be created. Details: Problem getting session data for driver type AndroidDriver; does it implement 'get driverData'?
