Fixture teardown (yield) in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a pytest fixture that uses yield for setup and teardown.

PyTest

import pytest

@pytest.fixture
def resource():
    print("Setup resource")
    [1]
    print("Teardown resource")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using return instead of yield causes teardown code to never run.

Using break or continue are invalid in this context.

The yield keyword in a pytest fixture pauses the function to provide the setup resource, then continues after the test for teardown.

medium

Complete the fixture to yield a value that tests can use.

PyTest

import pytest

@pytest.fixture
def data():
    setup_data = {'key': 'value'}
    [1] setup_data
    print("Cleanup after test")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using return ends the fixture immediately, skipping teardown.

Using print or raise does not provide the data correctly.

Using yield returns the setup data to the test, then runs cleanup after the test finishes.

hard

Fix the error in the fixture to ensure teardown runs after the test.

PyTest

import pytest

@pytest.fixture
def connection():
    print("Open connection")
    [1] 'conn'
    print("Close connection")

Drag options to blanks, or click blank then click option'

Cbreak

Dcontinue

💡 Hint

Common Mistakes

Using return causes teardown code to never execute.

Using break or continue is invalid syntax here.

Using yield pauses the fixture to provide the connection, then runs the close code after the test.

4fill in blank

hard

Fill both blanks to create a fixture that yields a resource and prints messages before and after the test.

PyTest

import pytest

@pytest.fixture
def file_resource():
    print("Opening file")
    [1] 'file'
    print([2])

Drag options to blanks, or click blank then click option'

Ayield

B"File closed"

C"File opened"

Dreturn

Attempts:

3 left

💡 Hint

Common Mistakes

Using return instead of yield skips teardown.

Printing "File opened" after yield is incorrect.

The fixture yields the resource, then prints "File closed" after the test finishes.

5fill in blank

hard

Fill all three blanks to create a fixture that sets up, yields a value, and cleans up with a print message.

PyTest

import pytest

@pytest.fixture
def setup_teardown():
    print([1])
    [2] 42
    print([3])

Drag options to blanks, or click blank then click option'

A"Setup started"

Byield

C"Teardown done"

Dreturn

Attempts:

3 left

💡 Hint

Common Mistakes

Using return instead of yield skips teardown.

Swapping setup and teardown messages.

The fixture prints setup message, yields the value 42, then prints teardown message after the test.
