Appium & Python: How to move to another app?

Question

I am making a testing bot with Python and Appium.

I need to extract the email of a button. I tired to extract href, but button are obviously something else than in smartphone applications.

So I click on this button which open my gmail with the New message window and the email in the "To" field.

SO I investigate and I could find only 1 tutoriel in Java :-(.

I found something else. SOmeone propose to instantiate new driver:

driver2 = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps2)
print("we setup driver2")
email = driver2.find_element_by_id("com.google.android.gm:id/to").text

But it stop immediately the browser. ANd Pycharm displayed this error:

Error Traceback (most recent call last): File "C:\\Users\\Nino\\AppData\\Local\\Programs\\Python\\Python37\\lib\\unittest\\case.py", line 59, in testPartExecutor yield File "C:\\Users\\Nino\\AppData\\Local\\Programs\\Python\\Python37\\lib\\unittest\\case.py", line 628, in run testMethod() File "C:\\Users\\Nino\\PycharmProjects\\mybot\\mybot_mybot.py", line 92, in test_scrap_email email = driver2.find_element_by_id("com.google.android.gm:id/to").text File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\selenium\\webdriver\\remote\\webdriver.py", line 360, in find_element_by_id return self.find_element(by=By.ID, value=id_) File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\appium\\webdriver\\webdriver.py", line 276, in find_element 'value': value})['value'] File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\selenium\\webdriver\\remote\\webdriver.py", line 321, in execute self.error_handler.check_response(response) File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\ap pium\\webdriver\\errorhandler.py", line 29, in check_response raise wde File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\appium\\webdriver\\errorhandler.py", line 24, in check_response super(MobileErrorHandler, self).check_response(response) File "C:\\Users\\Nino\\PycharmProjects\\mybot\\venv\\lib\\site-packages\\selenium\\webdriver\\remote\\errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.

I am using unittest which instantiate one driver going to 1 app (where there si the email button), then I instantiate in the middle of the code a new driver. But it bugs. And Icannot find anywhere an article or forum question about switching from 1 app to other app.

I prefer to let you te code of my bot:

Does anyone can help me please?

Answer 1

It seems like you just need switch context , you facing web in gmail , try :

driver2 = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps2)
print("we setup driver2")
driver2.switch_to.context('WEBVIEW_1')
email = driver2.find_element_by_id("com.google.android.gm:id/to").text

Or

# switch to webview
webview = driver.contexts.last
driver.switch_to.context(webview)

And please try without new initilize driver2

Please read this reference and this .

It looks like you're looking for start_activity function

The driver.start_activity method opens arbitrary activities on a device. If the activity is not part of the application under test, it will also launch the activity's application .

 driver.start_activity('com.foo.app', '.MyActivity') 

This way you should be able to switch between applications within the bounds of the same webdriver instance

You might also find Launch command useful as it is cross-platform approach allowing kicking off any installed application. The command is available via SeeTest Appium Extension .
