Conftest for shared fixtures in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of a conftest.py file in pytest?

The conftest.py file is used to define shared fixtures and hooks that can be used across multiple test files without importing them explicitly.

beginner

How do you define a fixture in conftest.py for Selenium WebDriver?

You define a function with the @pytest.fixture decorator that initializes the WebDriver, yields it for use in tests, and then quits the driver after tests finish.

beginner

Why is it better to put Selenium WebDriver setup in conftest.py instead of each test file?

Putting WebDriver setup in conftest.py avoids repeating code, makes tests cleaner, and ensures consistent setup and teardown across all tests.

What does the scope parameter in a pytest fixture control?

The scope parameter controls how often the fixture is invoked. For example, scope='function' runs before each test, scope='session' runs once per test session.

beginner

How can you use a fixture from conftest.py in your test function?

Simply add the fixture name as a parameter to your test function. Pytest will automatically find and inject the fixture from conftest.py.

What is the main benefit of using conftest.py for fixtures?

A To run tests in parallel automatically

B To write test cases faster

C To avoid using Selenium WebDriver

D To share fixtures across multiple test files without imports

The conftest.py file allows sharing fixtures across test files without explicit imports.

Which decorator is used to define a fixture in pytest?

A @pytest.test

B @pytest.fixture

C @pytest.setup

D @pytest.driver

Fixtures in pytest are defined using the @pytest.fixture decorator.

If you want a Selenium WebDriver fixture to run once per test session, which scope should you use?

A function

B module

C session

D class

Using scope='session' makes the fixture run once for the entire test session.

How do you ensure the WebDriver quits after a test using a fixture?

A Use yield in the fixture and call driver.quit() after yield

B Call driver.quit() inside the test

C Do nothing, it quits automatically

D Use a global variable

Using yield in the fixture allows setup before yield and teardown (like driver.quit()) after yield.

How do you use a fixture named browser in your test function?

A Add <code>browser</code> as a parameter to the test function

B Import browser and call it

C Call <code>pytest.browser()</code>

D Use <code>self.browser</code> inside the test

Pytest injects fixtures by matching parameter names in test functions.

Explain how to create and use a Selenium WebDriver fixture in conftest.py.

Think about setup and teardown using yield.

Describe the benefits of using conftest.py for shared fixtures in Selenium testing.

Consider how shared setup helps in many tests.
