Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a test case that checks if a function returns the expected result.

Testing Fundamentals

def test_addition():
    result = add(2, 3)
    assert result [1] 5

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

A==

B=

C!=

D<

💡 Hint

Common Mistakes

Using '=' instead of '==' in the assertion.

The assertion must check if the result is equal to 5 using '=='.

2fill in blank

medium

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

Testing Fundamentals

import pytest

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

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

ATrue

BNone

CFalse

D0

Attempts:

3 left

💡 Hint

Common Mistakes

Using False which causes the test to run instead of skipping.

The test is skipped when the condition is True, so use True.

3fill in blank

hard

Fix the error in the assertion to properly check if a list contains an item.

Testing Fundamentals

def test_contains():
    items = ['apple', 'banana', 'cherry']
    assert [1] in items

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

Aitems

B'banana'

C'grape'

Dbanana

💡 Hint

Common Mistakes

Forgetting quotes around the string item.

The item to check must be a string literal in quotes, so use 'banana'.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps words to their lengths only if length is greater than 3.

Testing Fundamentals

lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

B<

C>

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Using the word itself as value instead of its length.

Using '<' instead of '>' in the condition.

The dictionary maps each word to its length, so use len(word). The condition filters words longer than 3, so use >.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary with uppercase keys and values greater than 0.

Testing Fundamentals

result = [1]: [2] for [3], v in data.items() if v > 0}

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

Ak.upper()

Bv

Ck

Dvalue

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'value' instead of 'v' for values.

Using 'value' or 'v' instead of 'k' for keys in the loop.

Keys are converted to uppercase with k.upper(), values remain v, and the loop variable for keys is k.
