💡 Hint

Common Mistakes

Using 'Options' instead of 'ChromeOptions' causes an error because the import is specific.

💡 Hint

Common Mistakes

Passing a string instead of a list causes a type error.

Using 'disable-automation' is incorrect switch name.

The excludeSwitches option expects a list of strings. Using a list with 'enable-automation' disables the info bar.

💡 Hint

Common Mistakes

Using 'set_profile' instead of 'profile' attribute.

Passing 'profile_path' instead of 'firefox_profile' to driver.

The profile attribute of FirefoxOptions is set to the FirefoxProfile object. The firefox_profile parameter is passed to the Firefox driver.

Fill all three blanks to create ChromeOptions, add headless argument, and set window size.

Selenium Python

options = ChromeOptions()
options.add_argument([1])
options.add_argument([2])
driver = webdriver.Chrome(options=options)
# Verify window size is set to 1920x1080
size = driver.get_window_size()
assert size['width'] == [3] and size['height'] == 1080

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

A'--headless=new'

B'--window-size=1920,1080'

C1920

D'--headless'

Attempts:

💡 Hint

Common Mistakes

Using old '--headless' may cause different behavior.

Passing window size as separate arguments instead of one string.

Comparing width to string instead of integer.

Use '--headless=new' for modern headless mode, set window size with '--window-size=1920,1080', and check width as integer 1920.
