Fixture as function argument in PyTest - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a fixture in pytest?

A fixture is a function that sets up some data or state before a test runs and can be used by tests by declaring it as a function argument.

beginner

How do you use a fixture in a pytest test function?

You add the fixture name as a parameter to the test function. pytest will automatically call the fixture and pass its result to the test.

intermediate

Why is using fixtures as function arguments helpful?

It keeps tests clean and reusable by separating setup code from test logic, making tests easier to read and maintain.

beginner

What happens if a fixture returns a value?

The returned value is passed to the test function as the argument with the fixture's name.

intermediate

Can a test function use multiple fixtures as arguments?

Yes, you can list multiple fixture names as parameters, and pytest will provide each fixture's value to the test.

How do you tell pytest to use a fixture in a test?

A Import the fixture inside the test function

B Call the fixture function inside the test manually

C Add the fixture name as a parameter to the test function

D Use a decorator on the test function

pytest automatically injects fixtures when you list their names as test function parameters.

What does pytest do when a fixture is listed as a test function argument?

A Throws an error

B Ignores the fixture

C Runs the test before the fixture

D Runs the fixture and passes its return value to the test

pytest runs the fixture first and passes its result to the test function.

Can a fixture be used by more than one test function?

A Yes, fixtures are reusable

B No, fixtures are single-use

C Only if imported explicitly

D Only if decorated with @shared

Fixtures are designed to be reusable across multiple tests.

What is the main benefit of using fixtures as function arguments?

A Separates setup code from test logic

B Makes tests run faster

C Requires less code to write tests

D Allows tests to run in parallel

Fixtures help keep setup code separate, making tests cleaner and easier to maintain.

If a fixture returns a database connection, how do you access it in the test?

A By using a global variable

B By adding the fixture name as a test function argument

C By importing the fixture module

D By calling the fixture inside the test

The fixture's return value is passed to the test when you list the fixture name as an argument.
