Single parameter in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to parametrize the test with a single value.

PyTest

import pytest

@pytest.mark.parametrize('number', [[1]])
def test_is_positive(number):
    assert number > 0

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

A-3

B0

C5

D-1

💡 Hint

Common Mistakes

Using zero or negative numbers which cause the test to fail.

Forgetting to put the parameter inside a list.

The test is parametrized with the value 5, which is positive, so the assertion passes.

2fill in blank

medium

Complete the code to parametrize the test with multiple values using a single parameter.

PyTest

import pytest

@pytest.mark.parametrize('value', [1, 2, [1]])
def test_is_integer(value):
    assert isinstance(value, int)

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

A3.5

BNone

C'4'

D3

Attempts:

💡 Hint

Common Mistakes

Using a float or string instead of an integer.

Not including the parameter inside the list.

The parameter list includes 1, 2, and 3, all integers, so the test passes for all.

3fill in blank

hard

Fix the error in the code by completing the parameter list correctly.

PyTest

import pytest

@pytest.mark.parametrize('item', [1])
def test_not_none(item):
    assert item is not None

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

A[1, 2, 3]

B[None, 1, 2]

C1, 2, 3

DNone

💡 Hint

Common Mistakes

Passing a tuple instead of a list.

Including None which causes the test to fail.

The parameter list must be a list of values. Using [1, 2, 3] correctly passes the test.

4fill in blank

hard

Fill both blanks to parametrize the test with a single parameter and check for even numbers.

PyTest

import pytest

@pytest.mark.parametrize('[1]', [2, 4, 6, 8])
def test_is_even([2]):
    assert [2] % 2 == 0

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

💡 Hint

Common Mistakes

Using different names in the decorator and function argument.

Using names that do not match the parameter list.

Using 'num' as the parameter name in both places matches the parameterized values and the test argument.

5fill in blank

hard

Fill all three blanks to parametrize the test with a single parameter and assert it is a string.

PyTest

import pytest

@pytest.mark.parametrize('[1]', ['apple', 'banana', 'cherry'])
def test_is_string([2]):
    assert isinstance([3], str)

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

Dvalue

3 left

💡 Hint

Common Mistakes

Using different names in the decorator and function argument.

Mismatching the variable name in the assertion.

The parameter name 'fruit' is used in the decorator and as the function argument. The assertion checks if 'fruit' is a string.
