pytest with Selenium setup in Selenium Python - Test Execution Trace

Test Overview

This test opens a browser using Selenium with pytest, navigates to a website, checks the page title, and verifies it matches the expected title.

Test Code - pytest with Selenium

Selenium Python

import pytest
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options

@pytest.fixture

def driver():
    options = Options()
    options.add_argument('--headless')
    service = Service()
    driver = webdriver.Chrome(service=service, options=options)
    yield driver
    driver.quit()


def test_page_title(driver):
    driver.get('https://example.com')
    title = driver.title
    assert title == 'Example Domain', f"Expected title to be 'Example Domain' but got '{title}'"

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Pytest starts and sets up the Chrome WebDriver with headless option	Chrome browser instance is created but not visible (headless mode)	-	PASS
2	Browser navigates to 'https://example.com'	Browser loads the Example Domain webpage	-	PASS
3	Test retrieves the page title using driver.title	Page title is 'Example Domain'	Check if page title equals 'Example Domain'	PASS
4	Assertion verifies the page title matches expected	Title matches expected string	assert title == 'Example Domain'	PASS
5	Browser quits and test ends	Browser instance closed	-	PASS

Failure Scenario

Failing Condition: Page title does not match 'Example Domain' or page fails to load

Execution Trace Quiz - 3 Questions

What does the test check after opening the browser and navigating to the page?

A The page title matches 'Example Domain'

B The page URL contains 'example.com'

C The page has a button with id 'submit'

D The page background color is white

Key Result

Using pytest fixtures to set up and tear down Selenium WebDriver ensures clean browser sessions for each test and avoids leftover browser processes.
