Maximize and minimize window in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the output of this Selenium Python code snippet?

Consider the following Selenium Python code that opens a browser, maximizes the window, and then prints the window size.
What will be printed?

Selenium Python

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

options = Options()
service = Service()
driver = webdriver.Chrome(service=service, options=options)
driver.maximize_window()
size = driver.get_window_size()
print(size)
driver.quit()

A {'width': 1920, 'height': 1080}

B {'width': 0, 'height': 0}

C SyntaxError

D TypeError

💡 Hint

Maximizing the window sets it to the screen's full resolution size.

The maximize_window() method sets the browser window to full screen size. The get_window_size() method returns the current window size as a dictionary with width and height. So the printed output will be the screen resolution, e.g., {'width': 1920, 'height': 1080}.

❓ assertion

intermediate

Which assertion correctly verifies the browser window is minimized?

You want to write a test assertion to check if the browser window is minimized after calling driver.minimize_window(). Which assertion is correct?

Selenium Python

driver.minimize_window()
size = driver.get_window_size()

A assert size['width'] == 0 and size['height'] == 0

B assert size['width'] > 0 and size['height'] > 0

C assert size == None

D assert size['width'] == 1920 and size['height'] == 1080

💡 Hint

When minimized, the window size is usually zero in width and height.

Minimizing the window typically sets its size to zero width and height. So the assertion that both width and height are zero correctly verifies the window is minimized.

Why does this Selenium Python code fail to maximize the window?

The following code is intended to maximize the browser window but does not work as expected. What is the most likely reason?

Selenium Python

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window
print(driver.get_window_size())
driver.quit()

A get_window_size() returns None causing an error.

B The maximize_window method is not called because parentheses are missing.

C The Chrome driver is not initialized correctly.

D driver.quit() is called before maximize_window.

💡 Hint

Check if maximize_window is actually executed as a method.

The maximize_window method must be called with parentheses: maximize_window(). Without parentheses, it is just a reference to the method and does not execute, so the window is not maximized.

❓ framework

Which Selenium WebDriver method is best to restore a minimized window to normal size?

After minimizing a browser window using driver.minimize_window(), which method should you call to restore it to its previous normal size?

A driver.maximize_window()

B driver.restore_window()

C driver.set_window_size(width, height)

D driver.fullscreen_window()

💡 Hint

There is no restore_window() method in Selenium.

Selenium does not have a restore_window() method. To restore a minimized window, you can set its size explicitly using set_window_size(width, height). maximize_window() makes it full screen, which may not be the previous size.

🧠 Conceptual

What is the expected behavior of driver.minimize_window() across different operating systems?

Which statement best describes the behavior of driver.minimize_window() in Selenium WebDriver on Windows, macOS, and Linux?

A It always sets the window size to zero width and height on all OS.

B It throws an error on Linux because minimize is unsupported.

C It maximizes the window on macOS and Linux instead of minimizing.

D It minimizes the window on all OS, but the window size may not become zero on macOS and Linux.

💡 Hint

Window management behavior can vary by OS and browser driver implementation.

driver.minimize_window() minimizes the browser window on all OS, but the actual window size after minimizing may differ. On Windows, size often becomes zero, but on macOS and Linux, the window may be minimized without size zero.
