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

advanced

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.

Practice

1. What does the maximize_window() method do in Selenium WebDriver?

easy

A. It minimizes the browser window to the taskbar.

B. It closes the browser window.

C. It refreshes the current page.

D. It makes the browser window full screen.

Solution

1. Step 1: Understand the purpose of maximize_window()

   The method is designed to enlarge the browser window to fill the screen.

2. Step 2: Compare with other window methods

   Unlike minimize_window() which hides the window, maximize_window() expands it fully.

3. Final Answer:

   It makes the browser window full screen. -> Option D

4. Quick Check:

   maximize_window() = full screen [OK]

Hint: Maximize means full screen, minimize means hide [OK]

Common Mistakes:

• Confusing maximize with minimize
• Thinking maximize closes the window
• Assuming maximize refreshes the page

2. Which of the following is the correct syntax to minimize the browser window using Selenium in Python?

easy

A. driver.minimizeWindow()

B. driver.minimize()

C. driver.minimize_window()

D. driver.window.minimize()

Solution

1. Step 1: Recall Selenium WebDriver method names

   The correct method to minimize the window is minimize_window() called on the driver object.

2. Step 2: Check syntax correctness

   Options A, B, and C use incorrect method names or wrong casing.

3. Final Answer:

   driver.minimize_window() -> Option C

4. Quick Check:

   Correct method name = minimize_window() [OK]

Hint: Use exact method names with underscores in Selenium [OK]

Common Mistakes:

• Using camelCase instead of snake_case
• Calling minimize() without _window
• Trying to access window as a property

3. What will be the output of the following code snippet?

from selenium import webdriver

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

medium

A. {'width': 0, 'height': 0}

B. A dictionary with the current window width and height after maximizing

C. An error because get_window_size() is not a valid method

D. None

Solution

1. Step 1: Understand maximize_window() effect

   This method makes the browser window full screen, so the size will reflect the screen dimensions.

2. Step 2: Check get_window_size() output

   This method returns a dictionary with keys 'width' and 'height' showing current window size.

3. Final Answer:

   A dictionary with the current window width and height after maximizing -> Option B

4. Quick Check:

   maximize_window() + get_window_size() = size dict [OK]

Hint: get_window_size() returns dict with width and height [OK]

Common Mistakes:

• Expecting get_window_size() to return None or error
• Thinking maximize_window() does not affect size
• Confusing method names

4. Identify the error in the following Selenium Python code that tries to minimize the browser window:

from selenium import webdriver

driver = webdriver.Firefox()
driver.minimize()

medium

A. The method minimize() does not exist; should use minimize_window()

B. Firefox driver does not support window operations

C. Missing parentheses after webdriver.Firefox

D. minimize() should be called before creating the driver

Solution

1. Step 1: Check method name correctness

   The method to minimize the window is minimize_window(), not minimize().

2. Step 2: Verify driver and method compatibility

   Firefox driver supports window operations, so the error is due to wrong method name.

3. Final Answer:

   The method minimize() does not exist; should use minimize_window() -> Option A

4. Quick Check:

   Correct method = minimize_window() [OK]

Hint: Use full method names exactly as in docs [OK]

Common Mistakes:

• Using minimize() instead of minimize_window()
• Assuming Firefox driver lacks window methods
• Forgetting parentheses on driver creation

5. You want to test how your website behaves when the browser window is minimized and then maximized again. Which sequence of Selenium Python commands correctly achieves this?

hard

A. driver.minimize_window()
driver.maximize_window()

B. driver.maximize_window()
driver.minimize_window()

C. driver.set_window_size(0, 0)
driver.maximize_window()

D. driver.minimize()
driver.maximize()

Solution

1. Step 1: Minimize the window first

   Use minimize_window() to hide the browser window.

2. Step 2: Maximize the window after minimizing

   Use maximize_window() to restore it to full screen.

3. Step 3: Verify method correctness

   Options A, C, and D use incorrect methods or order; A reverses the intended test flow.

4. Final Answer:

   driver.minimize_window() driver.maximize_window() -> Option A

5. Quick Check:

   Minimize then maximize = B [OK]

Hint: Minimize first, then maximize to test window state changes [OK]

Common Mistakes:

• Reversing the order of minimize and maximize
• Using incorrect method names like minimize()
• Trying to set size to zero instead of minimizing
