Logging setup in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

💻 Command Output

What is the output of this Selenium Python logging setup?

Given the following Python code snippet configuring logging for Selenium, what will be printed to the console?

Selenium Python

import logging
from selenium import webdriver

logging.basicConfig(level=logging.INFO, format='%(levelname)s:%(message)s')
logger = logging.getLogger('selenium.webdriver.remote.remote_connection')

logger.info('Starting WebDriver')
driver = webdriver.Firefox()
logger.info('WebDriver started')
driver.quit()

A No output printed

B

Starting WebDriver
WebDriver started

C

DEBUG:Starting WebDriver
DEBUG:WebDriver started

D

INFO:Starting WebDriver
INFO:WebDriver started

💡 Hint

Check the logging level and format specified in basicConfig.

The logging level is set to INFO, so INFO messages are printed with the specified format including the level name.

❓ Configuration

intermediate

Which logging configuration disables Selenium's DEBUG logs?

You want to suppress DEBUG logs from Selenium WebDriver but keep INFO and above logs visible. Which logging configuration achieves this?

A logging.basicConfig(level=logging.WARNING)

B logging.basicConfig(level=logging.INFO)

C logging.basicConfig(level=logging.DEBUG)

D logging.basicConfig(level=logging.ERROR)

💡 Hint

DEBUG logs are lower than INFO level.

Setting level to INFO shows INFO, WARNING, ERROR, CRITICAL logs but hides DEBUG logs.

❓ Troubleshoot

advanced

Why does this Selenium Python logging code not print any logs?

Consider this code snippet: import logging logger = logging.getLogger('selenium.webdriver.remote.remote_connection') logger.info('Test log message') Why does it not print anything to the console?

A No logging configuration is set, so default level WARNING hides INFO messages

B The logger name is incorrect, so messages are discarded

C The info method is misspelled, causing no output

D The logger is disabled by default in Selenium

💡 Hint

Default logging level is WARNING if not configured.

Without configuring logging, the default level is WARNING, so INFO messages are ignored and not printed.

🔀 Workflow

advanced

What is the correct order to enable file logging for Selenium Python logs?

Arrange these steps in the correct order to log Selenium WebDriver messages to a file named 'selenium.log' with INFO level.

A 1,4,2,3

B 1,2,4,3

C 4,1,2,3

D 2,1,4,3

💡 Hint

You must create the handler before setting formatter and level, then add it to logger.

First create the FileHandler, then create and set the formatter, then set the level, and finally add the handler to the logger.

✅ Best Practice

expert

Which practice is best for managing Selenium Python logs in a CI/CD pipeline?

In a CI/CD environment, you want to capture Selenium WebDriver logs efficiently without cluttering the console. Which approach is best?

A Use print statements instead of logging for simplicity

B Disable all logging to avoid slowing down tests

C Configure logging to write to a rotating file handler and only show warnings/errors on console

D Print all logs to console with DEBUG level for full detail

💡 Hint

Consider log size and readability in automated environments.

Rotating file handlers prevent huge log files and showing only warnings/errors on console keeps output clean.
