Python Support?

[kiebak3r]

Does this currently support python?

Integrated into my test suite & cannot get it to find the element, it times out..

I can see JS uses driver.findElement where as the python equivelant is driver.find_element

Is python supported or am i doing something wrong?!

Any help would be great.

@kiebak3r

Does this currently support python? Yes. It's client agnostic. As the implementation is done on server side.

For some reason, your session gets terminated.

[debug] [AppiumDriver@0a01] Encountered internal error running command: NoSuchDriverError: A session is either terminated or not started

I also see the element is not present after the entire timeout is completed

[kiebak3r]

Do you have any recommendations on how to proceed?

If I remove the plug-in and add say a 10 second sleep timer, then the element is located and interacted with, then re adding the plug in and removing the sleep timer I get this error.

Thanks for your previous comment and any further advice would be great

[saikrishna321]

Can you share the code snippet and also fulllogs as gist please @kiebak3r

[kiebak3r]

As requested

https://gist.github.com/kiebak3r/b918fc5b67c9208a5c12dd0019ef9b1f

[saikrishna321]

Thanks @kiebak3r will look into it!

I notice client is sending css-selector and server is converting the request to android-matcher.

@KazuCocoa any idea?

[KazuCocoa]

What's the client version? Usually Appium Python client won't do the conversion. It is selenium client's behavior. Potentially Selenium client changed some method names so appium client need to update as same

[kiebak3r]

Currently running;

Appium-Python-Client - 2.7.1 selenium - 4.1.5 Appium Server - Appium v2.0.0-rc.3 Driver - uiautomator2@2.29.0

[saikrishna321]

@KazuCocoa In this line https://gist.github.com/kiebak3r/b918fc5b67c9208a5c12dd0019ef9b1f#file-without-plugin-txt-L174 the client is first sending with css-selector as locator strategy later UI2Driver is sending 'android uiautomator' as strategy to server - https://gist.github.com/kiebak3r/b918fc5b67c9208a5c12dd0019ef9b1f#file-without-plugin-txt-L178

I see UIA2 is doing this parsing - https://github.com/appium/appium-uiautomator2-driver/blob/master/lib/css-converter.js#L293-L308 Do you know why we decided this approach?

[KazuCocoa]

Python client sends css selector only when the find_element specifies it as https://github.com/appium/python-client/blob/fb8415edf11e5f7302e24df5c3354c0c69fe8776/appium/webdriver/webdriver.py#L379-L409 The id to css selector conversion is in the parent Selenium Python client behavior, appium client override them.

Do you know why we decided this approach?

We haven't provided CSS selector (and had no plant to support it in the native implementation side). Instead, to support the syntax, Dan added the conversion in the JS layer to use existing method in the native layer but to support CSS syntax only

[KazuCocoa]

Hm, latest https://github.com/SeleniumHQ/selenium/blob/b94159e08c5d45130ffa4cbe290d77fd6290a2d1/py/selenium/webdriver/remote/webdriver.py#L713 looks not break the existing behavior. I need to run the python client to see the behavior

[kiebak3r]

Any further update on this?

I will mention I did some more testing & noticed that the structure used in the original gist continues to not work - https://gist.github.com/kiebak3r/b918fc5b67c9208a5c12dd0019ef9b1f

But if I change the structure to use unit test framework then it works?? https://gist.github.com/kiebak3r/7268e6b9c2e061e02d7c0521eaffb96d

Any indication to why this might be the case?!

[saikrishna321]

I'm not a python person. @KazuCocoa can help

[KazuCocoa]

I haven't figured this out yet but maybe python's resolving dependency stuff...
