Parametrized fixtures in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a parametrized fixture with pytest.

PyTest

import pytest

@pytest.fixture(params=[1, 2, 3])
def number(request):
    return request.[1]

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

💡 Hint

Common Mistakes

Using request.params instead of request.param.

Trying to return request.value which does not exist.

The request.param attribute gives the current parameter value in a parametrized fixture.

Complete the test function to receive the parametrized fixture value.

PyTest

def test_is_positive([1]):
    assert [1] > 0

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

💡 Hint

Common Mistakes

Using param or request as parameter names instead of the fixture name.

Not including any parameter in the test function.

The test function must accept the fixture name as a parameter to receive its value.

3fill in blank

hard

Fix the error in the fixture to correctly parametrize it with strings.

PyTest

import pytest

@pytest.fixture(params=[1])
def greeting(request):
    return request.param

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

A"hello, hi, hey"

B('hello', 'hi', 'hey')

C['hello', 'hi', 'hey']

Dhello, hi, hey

💡 Hint

Common Mistakes

Passing a single string instead of a list of strings.

Passing unquoted words without brackets.

The params argument must be a list or tuple of values. A list literal with quotes is correct.

4fill in blank

hard

Fill both blanks to parametrize a fixture with numbers and use it in a test.

PyTest

import pytest

@pytest.fixture(params=[1])
def num(request):
    return request.param

def test_even([2]):
    assert [2] % 2 == 0

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

A[2, 4, 6]

Bnum

Cnumber

D[1, 3, 5]

💡 Hint

Common Mistakes

Using odd numbers in the params list.

Using a different parameter name in the test function than the fixture name.

The fixture is parametrized with even numbers in a list. The test function must accept the fixture name num to get the values.

5fill in blank

hard

Fill all three blanks to create a parametrized fixture with mixed types and test their types.

PyTest

import pytest

@pytest.fixture(params=[1])
def data(request):
    return request.param

def test_type([2]):
    assert isinstance([3], (int, str))

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

A[42, 'answer', 7]

Bdata

D[42, 7, 13]

Attempts:

3 left

💡 Hint

Common Mistakes

Using only integers in the params list.

Using different names for the test function parameter and the variable in the assertion.

The fixture is parametrized with a list containing integers and a string. The test function receives the fixture data and checks if its type is int or str.
