Why markers categorize and control tests in PyTest - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to mark the test as slow.

PyTest

import pytest

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

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

💡 Hint

Common Mistakes

Using 'fast' marker for a slow test.

Confusing 'skip' marker with categorizing tests.

Using 'parametrize' which is for test data, not categorization.

The @pytest.mark.slow marker labels the test as slow, so it can be selected or skipped during test runs.

medium

Complete the code to skip the test when a condition is true.

PyTest

import pytest

@pytest.mark.skipif([1], reason="Not supported")
def test_feature():
    assert True

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

A1 == 2

BFalse

CTrue

D2 > 3

💡 Hint

Common Mistakes

Using False which does not skip the test.

Using expressions that evaluate to False.

Confusing skipif condition with test assertions.

The @pytest.mark.skipif(True, reason=...) decorator skips the test unconditionally.

Fix the error in the marker usage to run tests with the 'network' marker only.

PyTest

# Run tests with pytest -m [1]
pytest

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

A'network'

BNetwork

Cnetwork_tests

Dnetwork

💡 Hint

Common Mistakes

Using uppercase marker names.

Adding quotes around the marker name.

Using a different marker name than defined.

The marker name is case-sensitive and should be used without quotes in the command line.

4fill in blank

hard

Fill both blanks to mark a test to run only on Linux and skip otherwise.

PyTest

import pytest
import sys

@pytest.mark.skipif(sys.platform != [1], reason="Only Linux")
def test_linux_only():
    assert True

# Run with pytest -m [2]

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

A'linux'

B'win32'

Clinux

Dlinux_only

💡 Hint

Common Mistakes

Using unquoted platform names in the condition.

Using wrong platform string like 'win32' for Linux.

Confusing marker name with platform string.

The platform string for Linux is 'linux' (with quotes). The marker name is linux_only to select the test.

5fill in blank

hard

Fill all three blanks to create a parametrized test with a marker and skip condition.

PyTest

import pytest

@pytest.mark.[1]
@pytest.mark.parametrize("input", [1, 2, 3])
@pytest.mark.skipif(input == [2], reason="Skip input 2")
def test_values(input):
    assert input != 0

# Run tests with pytest -m [3]

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

B2

💡 Hint

Common Mistakes

Using different marker names in code and command.

Using wrong skip condition value.

Forgetting to quote marker names in code.

The marker name is param. The skip condition checks if input equals 2. The run command uses the same marker name param.
