How to click Allow on Show Notifications popup using Selenium Webdriver

Please Follow below steps :

A) USING JAVA :

For Old Chrome Version (<50):

//Create a instance of ChromeOptions class
ChromeOptions options = new ChromeOptions();

//Add chrome switch to disable notification - "**--disable-notifications**"
options.addArguments("--disable-notifications");
        
//Set path for driver exe 
System.setProperty("webdriver.chrome.driver","path/to/driver/exe");

//Pass ChromeOptions instance to ChromeDriver Constructor
WebDriver driver =new ChromeDriver(options);

---

For New Chrome Version (>50):

//Create a map to store  preferences 
Map<String, Object> prefs = new HashMap<String, Object>();
    
//add key and value to map as follow to switch off browser notification
//Pass the argument 1 to allow and 2 to block
prefs.put("profile.default_content_setting_values.notifications", 2);
    
//Create an instance of ChromeOptions 
ChromeOptions options = new ChromeOptions();
    
// set ExperimentalOption - prefs 
options.setExperimentalOption("prefs", prefs);
    
//Now Pass ChromeOptions instance to ChromeDriver Constructor to initialize chrome driver which will switch off this browser notification on the chrome browser
WebDriver driver = new ChromeDriver(options);

---

For Firefox :

WebDriver driver ;
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("permissions.default.desktop-notification", 1);
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
driver = new FirefoxDriver(capabilities);
driver.get("http://google.com");

---

B) USING PYTHON :

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

option = Options()

option.add_argument("--disable-infobars")
option.add_argument("start-maximized")
option.add_argument("--disable-extensions")

# Pass the argument 1 to allow and 2 to block
option.add_experimental_option(
    "prefs", {"profile.default_content_setting_values.notifications": 1}
)

driver = webdriver.Chrome(
    chrome_options=option, executable_path="path-of-driver\chromedriver.exe"
)
driver.get("https://www.facebook.com")

C) USING C#:

ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-notifications"); // to disable notification
IWebDriver driver = new ChromeDriver(options);

import unittest
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
import time


class SendMsgSkype(unittest.TestCase):

    @classmethod
    def setUpClass(cls):

        options = Options()
        options.add_argument("--disable-notifications")

        cls.driver = webdriver.Chrome("./chromedriver.exe", chrome_options=options)

        cls.driver.implicitly_wait(5)
        cls.driver.maximize_window()
        cls.driver.get("https://web.skype.com/ru/")

It works for me. More details here: http://nullege.com/codes/show/src@t@a@[email protected]/21/selenium.webdriver.Chrome
