Built-in markers (skip, skipif, xfail) in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to skip the test unconditionally.

PyTest

import pytest

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

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

💡 Hint

Common Mistakes

Using @pytest.mark.skipif without a condition

Using @pytest.mark.xfail which marks expected failure, not skip

The @pytest.mark.skip() marker skips the test unconditionally.

2fill in blank

medium

Complete the code to skip the test only if Python version is less than 3.8.

PyTest

import pytest
import sys

@pytest.mark.[1](sys.version_info < (3, 8))
def test_feature():
    assert True

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

💡 Hint

Common Mistakes

Using @pytest.mark.skip without condition

Using @pytest.mark.xfail which marks expected failure

The @pytest.mark.skipif(condition) marker skips the test only if the condition is true.

3fill in blank

hard

Fix the error in the code to mark the test as expected to fail.

PyTest

import pytest

@pytest.mark.[1]()
def test_buggy():
    assert 1 == 2

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

💡 Hint

Common Mistakes

Using @pytest.mark.skip() which skips the test

Using @pytest.mark.skipif(True) which skips unconditionally

The @pytest.mark.xfail() marker marks the test as expected to fail.

4fill in blank

hard

Fill both blanks to skip the test if the platform is Windows and mark it as expected to fail otherwise.

PyTest

import pytest
import sys

@pytest.mark.[1](sys.platform == 'win32')
@pytest.mark.[2](sys.platform != 'win32')
def test_platform():
    assert False

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

💡 Hint

Common Mistakes

Using unconditional skip which can't be conditional

Mixing skip and skipif incorrectly

Use @pytest.mark.skipif(sys.platform == 'win32') to skip on Windows, and @pytest.mark.xfail(sys.platform != 'win32') to mark expected failure otherwise. The skipif takes precedence if its condition is true.

5fill in blank

hard

Fill the blanks to skip the test if Python version is less than 3.7, xfail if on Linux, and run normally otherwise.

PyTest

import pytest
import sys
import platform

@pytest.mark.[1](sys.version_info < (3, 7))
@pytest.mark.[2](platform.system() == 'Linux')
def test_conditions():
    assert True

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

💡 Hint

Common Mistakes

Using non-existent marker like xfailif

Using skip instead of skipif for version check

Use @pytest.mark.skipif(sys.version_info < (3, 7)) to skip if Python < 3.7, and @pytest.mark.xfail(platform.system() == 'Linux') to xfail on Linux. Runs normally if Python ≥ 3.7 and not Linux.
