Cannot Handle Pywinauto Related Exceptions With `try Except` Block In Python Properly?

My main goal: Automating Zoom my zoomModule.py file is: import os, pywinauto from pywinauto import Desktop from pywinauto import findwindows from pywinauto.application import Appli

Solution 1:

Seems like I have figured out how to print() the errors raised by pywinauto to the console/terminal without crashing my code with the help of this answer.

open_join_meeting_window function - Before ↓↓↓

# after importsdefopen_join_meeting_window():
    """opens the Join Meeting Popup Window; returns the Join Meeting Window"""
    zoomMainWin = get_Zoom_Main_Window()
    zoomMainWin["Zoom"].child_window(
        title="Home", control_type="TabItem"
    ).wrapper_object().click_input()
    zoomMainWin["Zoom"].child_window(
        title="Join", control_type="Button"
    ).wrapper_object().click_input()
    try:
        joinMeetingWin = app.connect(title="Join Meeting", timeout=15)
        print("Connected to Join Meeting Window.")
    except (findwindows.ElementNotFoundError, pywinauto.timings.TimeoutError) as e:
        print("Err before joinMeetingWin: ", e)
        pass

open_join_meeting_window function - after modification ↓↓↓

defopen_join_meeting_window():
    """opens the Join Meeting Popup Window; returns the Join Meeting Window"""
    zoomMainWin = get_Zoom_Main_Window()
    zoomMainWin["Zoom"].child_window(
        title="Home", control_type="TabItem"
    ).wrapper_object().click_input()
    zoomMainWin["Zoom"].child_window(
        title="Join", control_type="Button"
    ).wrapper_object().click_input()
    try:
        joinMeetingWin = app.connect(title="Join Meeting", timeout=15)
        print("Connected to Join Meeting Window.")
    except Exception as e:
        logging.error(traceback.format_exc())
        if e.__class__.__name__ == "TimeoutError":
            print("[TimeoutError]:- The `Join Meeting Window` is taking longer time to appear.")
    print("Passed the try-except block!!")
        pass

New terminal logs↓↓↓

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    joinMeetingWin = app.connect(title="hhh", timeout=6)

    raise err
pywinauto.timings.TimeoutError

[TimeoutError]:- The`Join Meeting Window` is taking longer time to appear.
Passed the try-except block!!

First, the traditional traceback is printed. Then the name of the error raised by pywinauto is used in the control-flow to decide what to do.

Solution 2:

Change this :

joinMeetingWin = app.connect(title="Join Meeting", timeout=6)

by this :

joinMeetingWin = app.connect(title="Join", timeout=6)
