使用python在appium中运行测试时如何防止每次重新安装应用程序

Question

I have written a python test suit for automation testing of an Android App . There are multiple test cases in this suit. I have put only 2 right now.

The problem is that, After each test case the app gets uninstalled, and installed back again. This happens with each test case. It takes so much time to get uninstalled and install back..

Appium version I am using is 1.5.0

I have tried using :

desired_caps['noReset'] = 'true'

desired_caps['fullReset'] = 'false'

and

appium --no-reset

But, of no use..

This is my python code file 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)

I have commented the quit statement in teardown function..

Please help me..

Answer 1

On appium version 1.5 they changed the command line argument, you should now use it this way:

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

More info available on appium's websites: http://appium.io/docs/en/writing-running-appium/default-capabilities-arg/

Answer 2

Comment this before each test case,

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

and run it only during the end of last test case. Since this will kill the appium session
