How do you set the logging level to show only warnings and errors?

Use logging.basicConfig(level=logging.WARNING) to show warnings and errors but hide info and debug messages.

What is the benefit of logging to a file instead of the console?

Logging to a file saves logs for later review. This helps when you want to check test results after they run or keep a history.

Show a simple example to set up logging in a Selenium Python script.

import logging
logging.basicConfig(filename='test.log', level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')

# Your Selenium code here
logging.info('Test finished')

A WARNING

B DEBUG

C ERROR

D INFO

DEBUG level shows detailed information useful for diagnosing problems.

What does the logging.basicConfig() function do?

A Sets up the logging system configuration

B Starts the Selenium browser

C Runs the test cases

It configures logging settings like level, format, and output destination.

Why might you want to log messages with timestamps?

A To know when events happened during the test

D To reduce log file size

Timestamps help track the timing of events and diagnose delays or failures.

TRACE is not a standard Python logging level; DEBUG is the most detailed.

How can you log an error message in Selenium Python?

Use logging.error() to log error messages properly.

Explain how to set up basic logging in a Selenium Python script and why it is useful.

Think about how logging helps track test progress and issues.
