Headless browser execution in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a headless Chrome browser instance.

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument([1])
driver = webdriver.Chrome(options=options)
driver.get('https://example.com')
driver.quit()

Drag options to blanks, or click blank then click option'

A"--headless"

B"--disable-gpu"

C"--start-maximized"

D"--incognito"

💡 Hint

Common Mistakes

Using arguments unrelated to headless mode like "--disable-gpu" or "--incognito".

Not adding any argument and expecting headless mode.

Adding the "--headless" argument tells Chrome to run without opening a visible window.

Complete the code to set up Firefox in headless mode using Selenium.

Selenium Python

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.[1] = True
driver = webdriver.Firefox(options=options)
driver.get('https://example.com')
driver.quit()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using unrelated properties like 'fullscreen' or 'incognito'.

Setting the property to a string instead of a boolean.

Setting options.headless = True enables Firefox to run without a GUI.

3fill in blank

hard

Fix the error in the code to correctly run Chrome in headless mode.

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument([1])
driver = webdriver.Chrome(options=options)
driver.get('https://example.com')
driver.quit()

Drag options to blanks, or click blank then click option'

A"--start-maximized"

B"--disable-extensions"

C"--headless"

D"--incognito"

💡 Hint

Common Mistakes

Not passing options to webdriver.Chrome() causes headless mode to be ignored.

Using wrong arguments that don't enable headless mode.

The code misses passing the options to Chrome driver. Adding the headless argument is correct, but options must be passed to webdriver.Chrome(options=options).

4fill in blank

hard

Fill both blanks to create a headless Chrome driver with disabled GPU.

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument([1])
options.add_argument([2])
driver = webdriver.Chrome(options=options)
driver.get('https://example.com')
driver.quit()

Drag options to blanks, or click blank then click option'

A"--headless"

B"--disable-gpu"

C"--start-maximized"

D"--incognito"

💡 Hint

Common Mistakes

Forgetting to disable GPU can cause rendering problems in headless mode.

Using unrelated arguments like "--incognito".

Headless mode requires "--headless" argument. Disabling GPU with "--disable-gpu" helps avoid some rendering issues in headless mode.

5fill in blank

hard

Fill all three blanks to create a Firefox headless driver, navigate to a page, and quit.

Selenium Python

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.[1] = True
driver = webdriver.Firefox(options=options)
driver.get([2])
driver.[3]()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Not setting headless to True causes the browser to open visibly.

Using incorrect method to close the browser like 'close' instead of 'quit'.

Passing URL without quotes causes syntax errors.

Set options.headless = True to run Firefox headless, navigate to the URL string, then call driver.quit() to close the browser.
