💡 Hint

Common Mistakes

Using height value instead of width for the first argument.

Passing string instead of integer.

The set_window_size method takes width and height as arguments. Here, width should be 1024.

💡 Hint

Common Mistakes

Using fullscreen_window() which is different from maximize.

Using minimize_window() which minimizes the window.

The maximize_window() method maximizes the browser window to full screen.

3fill in blank

💡 Hint

Common Mistakes

Using window_size which is not a valid property.

Using camelCase names which are not used in Python Selenium.

The get_window_size() method returns the current window size as a dictionary.

4fill in blank

hard

Fill both blanks to resize the window to 800 width and 600 height.

Selenium Python

driver.set_window_size([1], [2])

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

💡 Hint

Common Mistakes

Swapping width and height values.

Using incorrect values like 1024 or 768.

The set_window_size method requires width and height as arguments. Here, width is 800 and height is 600.

5fill in blank

hard

Fill all three blanks to get the window size and check if width is greater than 1000.

Selenium Python

size = driver.[1]
if size['[2]'] [3] 1000:
    print('Wide window')

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

💡 Hint

Common Mistakes

Using 'height' instead of 'width' for comparison.

Using comparison operators like '<' or '==' instead of '>'.

Use get_window_size() method to get size, access 'width' key, and compare with > operator.

Practice

1. What does the Selenium method set_window_size(width, height) do in a test script?

easy

A. It refreshes the current browser window.

B. It maximizes the browser window to full screen.

C. It changes the browser window size to the specified width and height.

D. It closes the browser window.

Solution

1. Step 1: Understand the method purpose

   The method set_window_size(width, height) is designed to set the browser window to a specific size.

2. Step 2: Compare with other window methods

   Maximizing, closing, or refreshing are done by different methods like maximize_window(), close(), or refresh().

3. Final Answer:

   It changes the browser window size to the specified width and height. -> Option C

4. Quick Check:

   set_window_size changes size [OK]

Hint: Remember: set_window_size sets exact width and height [OK]

Common Mistakes:

• Confusing set_window_size with maximize_window
• Thinking it closes or refreshes the window
• Using wrong method names

2. Which of the following is the correct syntax to set the browser window size to 1024x768 in Selenium Python?

easy

A. driver.set_window_size(1024, 768)

B. driver.setWindowSize(1024, 768)

C. driver.window_size(1024, 768)

D. driver.set_size(1024, 768)

Solution

1. Step 1: Identify correct method name and syntax

   The correct method in Selenium Python is set_window_size(width, height) with underscore and lowercase.

2. Step 2: Check method call format

   It is called on the driver object as driver.set_window_size(1024, 768).

3. Final Answer:

   driver.set_window_size(1024, 768) -> Option A

4. Quick Check:

   Correct method name and parameters [OK]

Hint: Use underscores and lowercase for Selenium Python methods [OK]

Common Mistakes:

• Using camelCase instead of snake_case
• Calling non-existent methods like set_size
• Missing driver object before method

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

driver.set_window_size(800, 600)
size = driver.get_window_size()
print(size)

medium

A. {'width': 800, 'height': 600}

B. {'width': 600, 'height': 800}

C. An error because get_window_size() does not exist

D. None

Solution

1. Step 1: Understand set_window_size effect

   The window size is set to width=800 and height=600.

2. Step 2: Check get_window_size output

   The method get_window_size() returns a dictionary with keys 'width' and 'height' reflecting the current window size.

3. Final Answer:

   {'width': 800, 'height': 600} -> Option A

4. Quick Check:

   get_window_size returns current size dict [OK]

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

Common Mistakes:

• Swapping width and height values
• Assuming get_window_size() does not exist
• Expecting a tuple instead of dict

4. Identify the error in this Selenium Python code snippet that tries to set the window size:

driver.set_window_size(1024)

medium

A. Method name should be setWindowSize, not set_window_size.

B. Missing the height parameter in set_window_size method.

C. The driver object is not defined.

D. set_window_size cannot be called directly on driver.

Solution

1. Step 1: Check method parameters

   The method set_window_size requires two parameters: width and height.

2. Step 2: Identify missing argument

   Only one argument (1024) is provided, so height is missing, causing a TypeError.

3. Final Answer:

   Missing the height parameter in set_window_size method. -> Option B

4. Quick Check:

   Two parameters required for set_window_size [OK]

Hint: Always provide both width and height to set_window_size [OK]

Common Mistakes:

• Providing only one parameter instead of two
• Using camelCase method name in Python
• Assuming driver is undefined without context

5. You want to test a website's responsive design by setting the browser window to three sizes: 320x480, 768x1024, and 1920x1080. Which code snippet correctly sets these sizes one after another with Selenium Python?

hard

A. sizes = [(320, 480), (768, 1024), (1920, 1080)]
for size in sizes:
driver.set_window_size(size)

B. sizes = [320, 480, 768, 1024, 1920, 1080]
for size in sizes:
driver.set_window_size(size)

C. driver.setWindowSize(320, 480)
driver.setWindowSize(768, 1024)
driver.setWindowSize(1920, 1080)

D. sizes = [(320, 480), (768, 1024), (1920, 1080)]
for w, h in sizes:
driver.set_window_size(w, h)

Solution

1. Step 1: Understand the sizes list format

   Sizes should be stored as tuples of (width, height) for easy unpacking.

2. Step 2: Use a for loop with unpacking

   Loop over sizes and unpack each tuple into width and height to call set_window_size(w, h).

3. Step 3: Eliminate incorrect options

   sizes = [320, 480, 768, 1024, 1920, 1080] for size in sizes: driver.set_window_size(size) uses a flat list and passes single integers (missing height parameter). driver.setWindowSize(320, 480) driver.setWindowSize(768, 1024) driver.setWindowSize(1920, 1080) uses camelCase setWindowSize (incorrect for Python Selenium). sizes = [(320, 480), (768, 1024), (1920, 1080)] for size in sizes: driver.set_window_size(size) loops but passes tuples directly (TypeError, expects two arguments).

4. Final Answer:

   sizes = [(320, 480), (768, 1024), (1920, 1080)] for w, h in sizes: driver.set_window_size(w, h) -> Option D

5. Quick Check:

   Use tuple unpacking for width and height [OK]

Hint: Use tuple unpacking in loop to set window sizes [OK]

Common Mistakes:

• Passing single integers instead of width and height pairs
• Calling set_window_size with a tuple instead of two arguments
• Using camelCase (setWindowSize) instead of snake_case
