Why is collecting screenshots useful during Selenium test failures?

When a Selenium test fails, why is it helpful to collect a screenshot at the moment of failure?

A It shows the exact state of the web page, helping to understand what went wrong visually.

B It speeds up the test execution by skipping other checks.

C It automatically fixes the error by refreshing the page.

D It deletes all cookies to reset the session.

💡 Hint

Think about how seeing the page helps you find problems.

A screenshot captures the page as it appeared during failure, giving visual clues that logs alone might miss.

How do logs support debugging in Selenium tests?

Why is it important to collect browser console logs during Selenium test runs?

A Logs automatically retry failed steps without user input.

B Logs increase the speed of the test by caching pages.

C Logs provide detailed error messages and warnings from the browser that help identify issues.

D Logs clear the browser history to avoid conflicts.

💡 Hint

Think about what information the browser console shows.

Browser console logs reveal JavaScript errors and warnings that can explain why a test failed.

What is the output of this Selenium Python code snippet?

Given the following Selenium Python code that collects a screenshot and saves it, what will be the result?

Selenium Python

import os

driver.get('https://example.com')
driver.save_screenshot('page.png')
print(os.path.exists('page.png'))

A True

B False

C SyntaxError

D FileNotFoundError

💡 Hint

Consider if the screenshot file is created after saving.

The save_screenshot method saves the image file, so checking its existence returns True.

📝 Syntax

Identify the syntax error in this Selenium Python code for collecting logs

Which option contains the correct syntax to collect browser logs in Selenium Python?

Selenium Python

logs = driver.get_log('browser')
for entry in logs:
    print(entry['message'])

A

logs = driver.get_log('browser')
for entry in logs:
print(entry['message'])

B

logs = driver.getLogs('browser')
for entry in logs:
    print(entry['message'])

C

logs = driver.get_log('browser')
for entry in logs
    print(entry['message'])

D

logs = driver.get_log('browser')
for entry in logs:
    print(entry['message'])

💡 Hint

Check method names and indentation carefully.

Option D uses the correct method name and proper Python indentation.

How to optimize evidence collection to reduce test runtime?

You want to collect screenshots only when a Selenium test step fails to save time. Which approach is best?

A Capture screenshots after every test step regardless of success or failure.

B Use try-except blocks around test steps and capture screenshots only in except blocks.

C Disable all evidence collection to speed up tests.

D Capture screenshots only before starting the test.

💡 Hint

Think about capturing evidence only when needed.

Capturing screenshots only on failure saves time and still provides useful debugging info.
