When finishing the script with "Ctrl+C" (KeyboardInterrupt) does not close Selenium Firefox

[emmalee]

I'm using the selenium to manipulate a page, when running the script it opens the firefox, but what I wanted to do is the following, if any problem happens in the script or if the user finishes, I want the firefox to close too.

I tried various things like:

Use the exit:

def __exit__(self):
    self.fechaAba()

Or the del:

def __del__(self):
    self.fechaAba()

The function I'm using is this, it's working, I use it in the exceptions to close the firefox when the error.

def fechaAba(self):
    try:
        self.__driver.driver.close()
    except:
        setLog("Firefox ja finalizado")

But for example if it tightens Ctrl + C to finish the script it does not close the firefox, the closest I got was using the atexit:

import atexit
def __init__(self):
    atexit.register(self.exit_handler)

def exit_handler(self):
    self.fechaAba()

It presents the message "Firefox already finished", but firefox remains open:

KeyboardInterrupt

[2017-09-28 15:16:41]: Firefox ja finalizado
[2017-09-28 15:16:42]: Firefox ja finalizado

When I use the driver.close() it enters the exception and presents the message "Firefox already finished", i.e. it failed to execute the command, and when I use quit the effect is similar, it usually performs the quit(Does not enter the exception), but the firefox remains open.

I made a small example:

from selenium import webdriver

import time

import atexit

class WhatsappAPI(object):
driver = None

def __init__(self):
    print "__init__"
    atexit.register(self.exit_handler)
    self.driver = webdriver.Firefox()
    self.driver.get("http://web.whatsapp.com")

def comeca_acao(self):
    while True:
        time.sleep(10)
        print "ok"

def exit_handler(self):
    print "exit_handler"
    self.driver.quit()

def __exit__(self):
    print "__exit__"
    self.driver.quit()

def __del__(self):
    print "__del__"
    self.driver.quit()

w = WhatsappAPI()

w.comeca_acao()

Result:

teste.py

init

Traceback (most recent call last):

File "C:\Users\Futurotec\Documents\futurofone_chat\branch\v3.12_externo\WhatsappBot - Instalador\Final\WhatsappWebAPI\teste.py", line 34, in <module>

w.comeca_acao()

File "C:\Users\Futurotec\Documents\futurofone_chat\branch\v3.12_externo\WhatsappBot - Instalador\Final\WhatsappWebAPI\teste.py", line 17, in comeca_acao

time.sleep(10)

KeyboardInterrupt

exit_handler

del

When it appears in the terminal "init" it opens firefox, when ctrl grip c the firefox continues open, what I want is that firefox closes to ctrl tightening c or when entering any exception. In exceptions it already works, but when ctrl tightening c not.

Try treating the KeyboardInterrupt exception when running the program, e.g.

try:    
  w = WhatsappAPI()
  w.comeca_acao()
except KeyboardInterrupt:
  w.driver.quit()
  print "Ate logo!"
