Selenium Python - Test Framework Integration (pytest)

In conftest.py, how do you create a Selenium WebDriver fixture that launches Chrome once before all tests run and closes it after all tests complete?

<pre>@pytest.fixture(scope='module')
def browser():
    driver = webdriver.Chrome()
    return driver
    driver.quit()</pre>

<pre>@pytest.fixture(scope='function')
def browser():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()</pre>

<pre>@pytest.fixture(scope='session')
def browser():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()</pre>

<pre>@pytest.fixture(scope='class')
def browser():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()</pre>

Step-by-Step Solution

Solution:

Step 1: Use session scope
Setting scope='session' ensures the fixture runs once per test session.
Step 2: Use yield to manage setup and teardown
Yield allows setup before tests and teardown after all tests finish.
Step 3: Properly quit the driver after tests
Calling driver.quit() after yield closes the browser cleanly.
Final Answer:
Fixture with session scope and yield -> Option C
Quick Check:
Session scope + yield for single browser instance [OK]

Quick Trick: Use session scope and yield for one browser per session [OK]

Common Mistakes:

Using function scope causing browser to open per test
Returning driver without yield prevents proper teardown
Using module or class scope opens browser multiple times
