Conftest for shared fixtures in Selenium Python - Test Execution Trace

Test Overview

This test uses a shared fixture from conftest.py to open a browser, navigate to a page, and verify the page title. It checks that the fixture correctly provides the WebDriver instance.

Test Code - PyTest

Selenium Python

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


def test_open_google(browser):
    browser.get('https://www.google.com')
    title = browser.title
    assert 'Google' in title

# conftest.py
import pytest
from selenium import webdriver

@pytest.fixture

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

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	PyTest starts and loads conftest.py to find fixtures	PyTest environment ready with browser fixture available	-	PASS
2	Test function test_open_google is called with browser fixture injected	Browser fixture creates Chrome WebDriver instance	-	PASS
3	Browser navigates to 'https://www.google.com'	Chrome browser opens Google homepage	-	PASS
4	Test retrieves page title from browser	Page title is 'Google'	Check if 'Google' is in page title	PASS
5	Test asserts that 'Google' is in the page title	Assertion passes because title contains 'Google'	assert 'Google' in title	PASS
6	Test completes, browser fixture quits the WebDriver	Chrome browser closes	-	PASS

Failure Scenario

Failing Condition: Browser fixture fails to create WebDriver or page title does not contain 'Google'

Execution Trace Quiz - 3 Questions

What does the browser fixture in conftest.py do?

A Checks the page title for correctness

B Defines the test function to run

C Creates and provides a WebDriver instance for tests

D Closes the browser after test completion

Key Result

Using a shared fixture in conftest.py helps reuse browser setup and teardown code across multiple tests, making tests cleaner and easier to maintain.
