Simple question: how to completely disable logging when using Selenium from Python bindings, ex code as follows:
browser = webdriver.Chrome()
I've tried things like:
options = webdriver.ChromeOptions();
options.add_argument('--log-level 3')
browser = webdriver.Chrome(chrome_options=options)
or even:
options = webdriver.ChromeOptions();
options.add_argument('--disable-logging')
browser = webdriver.Chrome(chrome_options=options)
but still the file 'chromedriver.log' is appearing on each new run of the tests.
You may set options.add_argument("--log-level=3") for Chrome browser to be run with Selenuim, or you may set logging level to some higher level with:
import logging
logger = logging.getLogger('selenium.webdriver.remote.remote_connection')
logger.setLevel(logging.WARNING) # or any variant from ERROR, CRITICAL or NOTSET
But some messages will appear anyway in this case, including the starting DevTools message or SSL handshake error messages.
To run Chrome browser with Selenium in console in completely silent mode, you should use this snippet:
options = Options()
options.headless = True
options.add_experimental_option("excludeSwitches", ["enable-logging"])
That trick will suppress any console message from either the Selenium driver or the browser itself, including the first message DevTools listening on ws://127.0.0.1 at the very start.
At the same time some runtime step-by-step data can be saved to service log file, in case its argument has been added.
driver = webdriver.Chrome(service_log_path='/dev/null')
The source code of Chrome's webdriver, shows the existence of an option called service_log_path.
So if you want to get rid of the file, you could set this property to
/dev/null if you are running under Linux/Unix ;
NUL under windows
Hope it helps
Just example for Windows people:
webdriver.Firefox(log_path='NUL')
Accepted answer is correct, but if you are new to Python / windows like i am, example like this will cut you few hours of google time.
To disable logging using Selenium and Python you need to add an experimental option through an instance of ChromeOptions() as follows:
add_experimental_option('excludeSwitches', ['enable-logging'])
Implementation
selenium4 compatible code
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
options = Options()
options.add_experimental_option('excludeSwitches', ['enable-logging'])
s = Service('C:\\BrowserDrivers\\chromedriver.exe')
driver = webdriver.Chrome(service=s, options=options)
this worked for me:
chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
courtesy of:
https://joshuatz.com/posts/2020/selenium-webdriver-disabling-chrome-logging-messages/
if you set service_log_path = None, it won't generate the geckodriver.log file:
driver = webdriver.Firefox(options=options, service_log_path=None)
I know this is old but this is still the first thing that comes up when you search for a way to prevent logging from selenium and it did not get rid of the "dev listening" messages for me and I found a way that does:
ChromeDriverService service = ChromeDriverService.CreateDefaultService();
service.HideCommandPromptWindow = true;
IWebDriver driver = new ChromeDriver(service,options);

I'm trying to initiate a tor browsing session through Tor Browser 9.5 which uses the default Firefox v68.9.0esr using GeckoDriver and Selenium through Python on a windows-10 system. But I'm facing an error as:
Code Block:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
import os
torexe = os.popen(r'C:\Users\username\Desktop\Tor Browser\Browser\TorBrowser\Tor\tor.exe')
profile = FirefoxProfile(r'C:\Users\username\Desktop\Tor Browser\Browser\TorBrowser\Data\Browser\profile.default')
profile.set_preference('network.proxy.type', 1)
profile.set_preference('network.proxy.socks', '127.0.0.1')
profile.set_preference('network.proxy.socks_port', 9050)
profile.set_preference("network.proxy.socks_remote_dns", False)
profile.update_preferences()
firefox_options = webdriver.FirefoxOptions()
firefox_options.binary_location = r'C:\Users\username\Desktop\Tor Browser\Browser\firefox.exe'
driver = webdriver.Firefox(firefox_profile= profile, options = firefox_options, executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get("https://www.tiktok.com/")
Where as the same code block works through Firefox and Firefox Nightly using the respective binaries.
Do I need any additional settings? Can someone help me out?
Firefox Snapshot:
Firefox Nightly Snapshot:
I managed to resolve this by updating to v9.5.1 and implementing the following changes:
Note that although the code is in C# the same changes to the Tor browser and how it is launched should be applied.
FirefoxProfile profile = new FirefoxProfile(profilePath);
profile.SetPreference("network.proxy.type", 1);
profile.SetPreference("network.proxy.socks", "127.0.0.1");
profile.SetPreference("network.proxy.socks_port", 9153);
profile.SetPreference("network.proxy.socks_remote_dns", false);
FirefoxDriverService firefoxDriverService = FirefoxDriverService.CreateDefaultService(geckoDriverDirectory);
firefoxDriverService.FirefoxBinaryPath = torPath;
firefoxDriverService.BrowserCommunicationPort = 2828;
var firefoxOptions = new FirefoxOptions
{
Profile = null,
LogLevel = FirefoxDriverLogLevel.Trace
};
firefoxOptions.AddArguments("-profile", profilePath);
FirefoxDriver driver = new FirefoxDriver(firefoxDriverService, firefoxOptions);
driver.Navigate().GoToUrl("https://www.google.com");
Important notes:
The following TOR configs need to be changed in about:config :
marionette.enabled: true
marionette.port: set to an unused port, and set this value to firefoxDriverService.BrowserCommunicationPort in your code. This was set to 2828 in my example.
note:
I am not sure whether this really is the definite answer (thus, I'd really appreciate feedback)
solution:
I've managed to send a get request to the check tor page (https://check.torproject.org/) and it displayed an unknown IP to me (additionally, IPs differ if you repeat the request after a time)
Essentially, I've set up the chrome driver to run TOR. Here's the code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
tor_proxy = "127.0.0.1:9150"
chrome_options = Options()
chrome_options.add_argument("--test-type")
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--disable-extensions')
chrome_options.add_argument('disable-infobars')
chrome_options.add_argument("--incognito")
chrome_options.add_argument('--proxy-server=socks5://%s' % tor_proxy)
driver = webdriver.Chrome(options=chrome_options)
driver.get('https://check.torproject.org/')
Because the driver is not in headless mode you can inspect the resulting page yourself. It should read:
"Congratulations. This browser is configured to use Tor. [IP Info]. However, it does not appear to be Tor Browser. Click here to go to the download page"
Make sure that the chromedriver.exe file is linked on the path or provide the path to the file as an argument to the driver.Chrome() function.
Edit: make sure TOR browser is running in the background, thanks #Abhishek Rai for pointing that out
I'm looking at this code:
#! python3
from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options
opts = Options()
opts.set_headless()
assert opts.headless # Operating in headless mode
browser = Firefox(options=opts)
browser.get('https://duckduckgo.com')
source: https://realpython.com/modern-web-automation-with-python-and-selenium/
the idea is to call a headless browser but I don't understand the logic behind this code. What is 'options', and what is 'Options'? What do they exactly do? what options=opts stands for?
Now trying to run this code and the webpage duckduckgo won't open. Any idea why?
Options is a class in the selenium firefox webdriver package.
opts is an instance of the Options class instantiated for the program.
When the code says:
opts = Options()
Python creates an instance of the class, and uses the the variable opts as the access point.
When the code says:
opts.set_headless()
Python is updating the instance of Options, to store the information “the user of this wants to start a headless instance of the browser”
When the code says:
browser = Firefox(options=opts)
Python is creating an instance of the Firefox class, and sending it the opts variable to configure the new instance. In this case, the only option that has been modified from the defaults is the headless flag.
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
import time
#--| Setup
options = Options()
options.add_argument("--headless")
caps = webdriver.DesiredCapabilities().FIREFOX
caps["marionette"] = True
browser = webdriver.Firefox(firefox_options=options, capabilities=caps, executable_path=r"geckodriver.exe")
#--| Parse
browser.get('https://duckduckgo.com')
logo = browser.find_elements_by_css_selector('#logo_homepage_link')
print(logo[0].text)
this code works ( gives output About DuckDuckGo ). I was told that opts.set_headless() is deprecated, maybe that's why it didn't give me any result.
I used to set up proxy on chrome like in a code below, but when i updated to selenium 3.8.1 proxy stops working, i dont get any errors it just doesn't use proxy server and i dont know why. My chromedriver is also up to date.
options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=192.99.55.120:3128')
driver = webdriver.Chrome(executable_path='C:\chromedriver_win32\chromedriver.exe', chrome_options=options)
driver.get("http://google.com/")
Would like to receive any advice, maybe alternative way to set up proxy for chromedriver.
If someone still interested, this is how i have finally solved the problem
from selenium.webdriver import Proxy
settings = {
"httpProxy": "192.99.55.120:3128",
"sslProxy": "192.99.55.120:3128"
}
proxy = Proxy(settings)
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
cap = DesiredCapabilities.CHROME.copy()
cap['platform'] = "WINDOWS"
cap['version'] = "10"
proxy.add_to_capabilities(cap)
from selenium.webdriver.chrome.webdriver import WebDriver as ChromeDriver
driver = ChromeDriver(desired_capabilities=cap, executable_path='C:\chromedriver_win32\chromedriver.exe')
try
options.add_argument('--proxy-server="http=192.99.55.120:3128;https=192.99.55.120:3128"')
also try running your chrome binary directly with these params to see whether it works or not
chrome.exe --proxy-server="http=192.99.55.120:3128"
If the navigator asks for the credentials username and password for the proxy and you need to handle this : (only if the alert come up)
driver.get("http://username:password#google.com/")
I am working on downloading HAR from Chrome for YouTube through Selenium Python Script.
Code Snippet:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={0}".format(url))
chrome_options.add_argument("--enable-quic")
self.driver = webdriver.Chrome(chromedriver,chrome_options = chrome_options)
self.proxy.new_har(args['url'], options={'captureHeaders': True})
self.driver.get(args['url'])
result = json.dumps(self.proxy.har, ensure_ascii=False)
I want QUIC to be used whenever I download HAR but when I look at the packets through Wireshark Selenium driver is using TCP only. Is there a way to force Chrome Driver to use QUIC? Or Is there an alternate to BMP?
A similar thing has been asked for Firefox in this question How to capture all requests made by page in webdriver? Is there any alternative to Browsermob? and there was a solution with Selenium alone without need of any BMP. So is it possible for Chrome?
Workaround for this problem could be: start Chrome normally (with your default profile or create another profile) and enable quic manually. Then start chromedriver with your profile loaded.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=/home/user/.config/google-chrome")
driver = webdriver.Chrome(executable_path="/home/user/Downloads/chromedriver", chrome_options=options)
I am trying to submit information in a webpage, but selenium throws this error:
UnexpectedAlertPresentException: Alert Text: This page is asking you
to confirm that you want to leave - data you have entered may not be
saved. ,
>
It's not a leave notification; here is a pic of the notification -
.
If I click in never show this notification again, my action doesn't get saved; is there a way to save it or disable all notifications?
edit: I'm using firefox.
You can disable the browser notifications, using chrome options. Sample code below:
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
With the latest version of Firefox the above preferences didn't work.
Below is the solution which disable notifications using Firefox object
_browser_profile = webdriver.FirefoxProfile()
_browser_profile.set_preference("dom.webnotifications.enabled", False)
webdriver.Firefox(firefox_profile=_browser_profile)
Disable notifications when using Remote Object:
webdriver.Remote(desired_capabilities=_desired_caps, command_executor=_url, options=_custom_options, browser_profile=_browser_profile)
selenium==3.11.0
Usually with browser settings like this, any changes you make are going to get throws away the next time Selenium starts up a new browser instance.
Are you using a dedicated Firefox profile to run your selenium tests? If so, in that Firefox profile, set this setting to what you want and then close the browser. That should properly save it for its next use. You will need to tell Selenium to use this profile though, thats done by SetCapabilities when you start the driver session.
This will do it:
from selenium.webdriver.firefox.options import Options
options = Options()
options.set_preference("dom.webnotifications.enabled", False)
browser = webdriver.Firefox(firefox_options=options)
For Google Chrome and v3 of Selenium you may receive "DeprecationWarning: use options instead of chrome_options", so you will want to do the following:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
options = webdriver.ChromeOptions()
options.add_argument('--disable-notifications')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
Note: I am using webdriver-manager, but this also works with specifying the executable_path.
This answer is an improvement on TH Todorov code snippet, based on what is working as of Chrome (Version 80.0.3987.163).
lk = os.path.join(os.getcwd(), "chromedriver",) --> in this line you provide the link to the chromedriver, which you can download from chromedrive link
import os
from selenium import webdriver
lk = os.path.join(os.getcwd(), "chromedriver",)
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(lk, options=chrome_options)
