1661620 - Switching focus to a window handle via the driver throws an undefined error

Status: UNCONFIRMED

(Core :: Widget: Cocoa, defect, P5)

Description

[iamjohnnywang]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.135 Safari/537.36

Steps to reproduce:

Noticed this when our WebdriverIO (v4) tests run via Saucelabs suddenly started failing. Not sure how to reproduce outside the context of the testing framework (or what the underlying Selenium/protocol commands are), but this was experienced with the v80 of the Firefox driver:

1. Run a test via WDIO that opens up a new popup window
2. Get the window handle (via browser.windowHandles())

COMMAND GET "/wd/hub/session/eb8c5ca47c8d4eb0aa3dbbb2780ca869/window_handles"
DATA {}
RESULT ["22","4294967300"]

3. Try to focus on the window handle (via browser.switchTab(popupWindowHandle))
   calling ` started failing with

COMMAND POST "/wd/hub/session/eb8c5ca47c8d4eb0aa3dbbb2780ca869/window"
DATA {"name":"4294967300","handle":"4294967300"}

Actual results:

The switch/focus command fails with "Expected "handle" to be a string, got [object Undefined] undefined", even though a handle string is definitely being passed into the command.

Expected results:

The switch/focus command should work

Hi iamjohnnywang,

Thanks for your report.

I don't have the specific setup to test it on my end but I'll add this ticket to the Widget: cocoa component in the hope someone from their team can take a look.

Best,
Virginia
