Parameterize with test data in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the pytest module needed for parameterization.

Selenium Python

import [1]

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

Apytest

Bselenium

Crequests

Dunittest

💡 Hint

Common Mistakes

Importing unittest instead of pytest

Forgetting to import any testing module

We use pytest to enable parameterized tests in Python.

2fill in blank

medium

Complete the code to add the pytest decorator for parameterizing the test with two inputs.

Selenium Python

@pytest.mark.[1]("input,expected")
def test_example(input, expected):
    assert input + 1 == expected

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

Afixture

Bskip

Cmark

Dparametrize

💡 Hint

Common Mistakes

Using @pytest.mark.fixture instead

Misspelling the decorator name

The @pytest.mark.parametrize decorator allows running the test with different inputs.

3fill in blank

hard

Fix the error in the parameterized test data format by completing the code.

Selenium Python

@pytest.mark.parametrize("input,expected", [
    (1, 2),
    (2, [1]),
    (3, 4)
])
def test_add_one(input, expected):
    assert input + 1 == expected

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

💡 Hint

Common Mistakes

Using wrong expected values that do not match input + 1

Syntax errors in the list of tuples

The expected value for input 2 should be 3, since 2 + 1 = 3.

4fill in blank

hard

Fill both blanks to create a parameterized test that checks if a string contains a substring.

Selenium Python

@pytest.mark.parametrize("text,substring")
def test_contains(text, substring):
    assert [1] in [2]

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

Asubstring

Btext

Attempts:

3 left

💡 Hint

Common Mistakes

Reversing the order of substring and text

Using equality instead of 'in'

The test checks if the substring is inside the text, so substring in text is correct.

5fill in blank

hard

Fill all three blanks to create a parameterized test that checks if a number is within a range.

Selenium Python

@pytest.mark.parametrize("num,low,high")
def test_in_range(num, low, high):
    assert [1] <= [2] <= [3]

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

Alow

Bnum

Attempts:

3 left

💡 Hint

Common Mistakes

Swapping num with low or high

Using separate comparisons instead of chained

The test asserts that num is between low and high, so the correct order is low <= num <= high.
