pytest-timeout for time limits - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set a timeout of 5 seconds for the test function.

PyTest

import pytest

@pytest.mark.timeout([1])
def test_example():
    assert 1 + 1 == 2

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

💡 Hint

Common Mistakes

Using zero or None as timeout disables the timeout.

Forgetting to import pytest.

The @pytest.mark.timeout(5) decorator sets a 5-second timeout for the test.

2fill in blank

medium

Complete the code to apply a timeout of 3 seconds using a pytest fixture.

PyTest

import pytest

@pytest.fixture(autouse=True)
def set_timeout():
    pytest.timeout = [1]


def test_fast():
    assert True

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

💡 Hint

Common Mistakes

Setting timeout to zero disables it.

Not using autouse=True to apply fixture automatically.

Setting pytest.timeout = 3 inside an autouse fixture applies a 3-second timeout to tests.

3fill in blank

hard

Fix the error in the code to correctly apply a 2-second timeout to the test.

PyTest

import pytest

@pytest.mark.timeout([1])
def test_slow():
    import time
    time.sleep(3)
    assert True

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

💡 Hint

Common Mistakes

Setting timeout equal or greater than sleep time does not cause timeout.

Using negative timeout values.

The timeout must be less than the sleep time to trigger a timeout failure. Using 2 seconds works.

4fill in blank

hard

Fill both blanks to set a timeout of 4 seconds and handle the timeout exception in the test.

PyTest

import pytest
from pytest_timeout import TimeoutException

@pytest.mark.timeout([1])
def test_timeout_handling():
    try:
        import time
        time.sleep(5)
    except [2]:
        assert True

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

💡 Hint

Common Mistakes

Catching wrong exception type.

Setting timeout longer than sleep time.

Use @pytest.mark.timeout(4) to set timeout and catch TimeoutException to handle it.

5fill in blank

hard

Fill all three blanks to apply a 6-second timeout, skip the test if it times out, and import the correct decorator.

PyTest

import pytest
from pytest_timeout import [1]

@[2].timeout([3])
def test_skip_on_timeout():
    import time
    time.sleep(10)
    assert True

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

💡 Hint

Common Mistakes

Importing wrong names from pytest_timeout.

Using incorrect decorator syntax.

Import mark from pytest_timeout and use @mark.timeout(6) to set a 6-second timeout.
