Fixtures for browser setup/teardown in Selenium Python - Test Execution Trace

Test Overview

This test uses a fixture to open a browser before the test and close it after. It verifies that the page title is correct after navigating to the website.

Test Code - pytest

Selenium Python

import pytest
from selenium import webdriver
from selenium.webdriver.common.by import By

@pytest.fixture
def browser():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()

def test_page_title(browser):
    browser.get('https://example.com')
    assert browser.title == 'Example Domain'

Execution Trace - 4 Steps

Step	Action	System State	Assertion	Result
1	Pytest fixture 'browser' starts: opens Chrome browser	Chrome browser window opens, ready for commands	-	PASS
2	Test navigates browser to 'https://example.com'	Browser loads the Example Domain webpage	-	PASS
3	Test checks that page title equals 'Example Domain'	Page title is 'Example Domain'	assert browser.title == 'Example Domain'	PASS
4	Test ends, fixture 'browser' teardown runs: closes browser	Chrome browser window closes	-	PASS

Failure Scenario

Failing Condition: Page title does not match 'Example Domain' after navigation

Execution Trace Quiz - 3 Questions

What does the fixture 'browser' do in this test?

A It runs the test code inside the browser

B It opens the browser before the test and closes it after

C It only opens the browser but does not close it

D It checks the page title automatically

Key Result

Using fixtures for browser setup and teardown ensures tests start with a fresh browser and clean up resources, making tests reliable and preventing leftover browser instances.
