Window size control in Selenium Python - Test Execution Trace

Test Overview

This test opens a browser, sets the window size to 1024x768 pixels, and verifies that the window size is correctly applied.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
import time

# Initialize Chrome WebDriver
service = Service()
driver = webdriver.Chrome(service=service)

try:
    # Open a website
    driver.get('https://example.com')

    # Set window size to 1024x768
    driver.set_window_size(1024, 768)

    # Get current window size
    size = driver.get_window_size()

    # Assert window size is as expected
    assert size['width'] == 1024 and size['height'] == 768, f"Window size is {size}, expected 1024x768"

finally:
    driver.quit()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Initialize Chrome WebDriver	Browser is starting but not yet opened any page	-	PASS
2	Open the URL 'https://example.com'	Browser displays the Example Domain homepage	-	PASS
3	Set browser window size to width=1024 and height=768	Browser window is resized to 1024x768 pixels	-	PASS
4	Retrieve current window size	Browser window size info is fetched	Check if width == 1024 and height == 768	PASS
5	Assert that window size matches 1024x768	Window size is confirmed as 1024x768	Assertion passes if size matches expected values	PASS
6	Close the browser	Browser is closed and WebDriver session ends	-	PASS

Failure Scenario

Failing Condition: Window size after setting does not match 1024x768

Execution Trace Quiz - 3 Questions

What does the test verify after setting the window size?

A That the page title contains 'Example Domain'

B That the browser navigated to the correct URL

C That the browser window size is exactly 1024x768 pixels

D That the browser window is maximized

Key Result

Always verify that window size changes are applied by retrieving the size after setting it, to ensure your test environment matches expected conditions.
