Disable logging selenium python

How to disable logging using Selenium with Python binding

Simple question: how to completely disable logging when using Selenium from Python bindings, ex code as follows:

options = webdriver.ChromeOptions(); options.add_argument('--log-level 3') browser = webdriver.Chrome(chrome_options=options) 

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.

Solution 1:

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.

Solution 2:

driver = webdriver.Chrome(service_log_path='/dev/null') 

Solution 3:

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.

Solution 4:

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

Solution 5:

chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])

How to disable logging using selenium with python binding?

When using Selenium with Python binding for web automation, the logging mechanism can generate a large amount of output that can be distracting or interfere with the output of your script. To resolve this issue, you may want to disable logging for Selenium. There are a few methods to accomplish this.

Method 1: Disable logging globally using the logging module

To disable logging globally using the logging module in Python with Selenium, you can follow these steps:

logging.basicConfig(level=logging.CRITICAL)

from selenium import webdriver options = webdriver.ChromeOptions() options.add_argument('--disable-logging') driver = webdriver.Chrome(options=options)

import logging from selenium import webdriver logging.basicConfig(level=logging.CRITICAL) options = webdriver.ChromeOptions() options.add_argument('--disable-logging') driver = webdriver.Chrome(options=options)

This code will disable logging globally using the logging module in Python with Selenium.

Method 2: Set log level for individual loggers

To disable logging using Selenium with Python binding, you can use the «Set log level for individual loggers» method. Here are the steps and code examples:

Step 1: Import the necessary libraries:

import logging from selenium.webdriver.remote.remote_connection import LOGGER

Step 2: Set the log level for the logger you want to disable. In this case, we will disable the «remote_connection» logger:

LOGGER.setLevel(logging.WARNING)

Step 3: Create a new instance of the WebDriver with the desired options. In this case, we will use the Chrome driver:

from selenium import webdriver options = webdriver.ChromeOptions() options.add_argument('--disable-logging') driver = webdriver.Chrome(options=options)

Step 4: Use the WebDriver instance to navigate to the desired webpage:

driver.get('https://www.example.com')

Step 5: Close the WebDriver instance:

Putting it all together, the complete code would look like this:

import logging from selenium.webdriver.remote.remote_connection import LOGGER from selenium import webdriver LOGGER.setLevel(logging.WARNING) options = webdriver.ChromeOptions() options.add_argument('--disable-logging') driver = webdriver.Chrome(options=options) driver.get('https://www.example.com') driver.quit()

This code will disable logging for the «remote_connection» logger and create a new instance of the Chrome driver with logging disabled. The WebDriver instance will then navigate to the desired webpage and close the driver.

Method 3: Use a custom logging configuration file

To disable logging using Selenium with Python binding, you can use a custom logging configuration file. Follow the steps below to do so:

[loggers] keys=root [handlers] keys=consoleHandler [formatters] keys=simpleFormatter [logger_root] level=WARNING handlers=consoleHandler [handler_consoleHandler] class=StreamHandler level=WARNING formatter=simpleFormatter args=(sys.stdout,) [formatter_simpleFormatter] format=%(asctime)s - %(name)s - %(levelname)s - %(message)s datefmt=%Y-%m-%d %H:%M:%S

import logging.config logging.config.fileConfig('logging_config.ini')

from selenium import webdriver options = webdriver.ChromeOptions() options.add_argument('--log-level=3') driver = webdriver.Chrome(options=options)

In the code above, —log-level=3 sets the log level to WARNING , which is the level specified in the configuration file.

That’s it! You have successfully disabled logging using a custom logging configuration file in Selenium with Python binding.

if you set service_log_path = None, it won’t generate the geckodriver.log file:

driver = webdriver.Firefox(options=options, service_log_path=None)
