Testing multiple exceptions in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to test if a ValueError is raised.

PyTest

import pytest

def test_value_error():
    with pytest.raises([1]):
        int('abc')

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

ATypeError

BValueError

CKeyError

DIndexError

💡 Hint

Common Mistakes

Using TypeError instead of ValueError

Not using pytest.raises context manager

The pytest.raises() function expects the exception type to check. Here, int('abc') raises a ValueError.

2fill in blank

medium

Complete the code to test if a ZeroDivisionError is raised.

PyTest

import pytest

def test_zero_division():
    with pytest.raises([1]):
        result = 10 / 0

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

AValueError

BOverflowError

CArithmeticError

DZeroDivisionError

💡 Hint

Common Mistakes

Using ValueError or ArithmeticError instead of ZeroDivisionError

Not using the context manager correctly

Dividing by zero raises a ZeroDivisionError. The test checks for this specific exception.

3fill in blank

hard

Fix the error in the test to correctly check for multiple exceptions.

PyTest

import pytest

def test_multiple_exceptions():
    with pytest.raises(([1])):
        int('abc')
        result = 10 / 0

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

AValueError, ZeroDivisionError

BValueError ZeroDivisionError

C[ValueError, ZeroDivisionError]

D['ValueError', 'ZeroDivisionError']

💡 Hint

Common Mistakes

Using a list instead of a tuple

Passing exception names as strings

To test multiple exceptions, pass a tuple of exception types without brackets or quotes around the types.

4fill in blank

hard

Fill both blanks to test if either KeyError or IndexError is raised.

PyTest

import pytest

def test_key_or_index_error():
    with pytest.raises(([1], [2])):
        d = {}
        _ = d['missing_key']

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

AKeyError

BIndexError

CValueError

DTypeError

Attempts:

3 left

💡 Hint

Common Mistakes

Using ValueError or TypeError instead

Not passing a tuple of exceptions

The test checks for either KeyError or IndexError. Both are valid exceptions to catch here.

5fill in blank

hard

Fill all three blanks to test if either AttributeError, TypeError, or ValueError is raised.

PyTest

import pytest

def test_multiple_exceptions_complex():
    with pytest.raises(([1], [2], [3])):
        obj = None
        obj.some_method()

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

AAttributeError

BTypeError

CValueError

DKeyError

Attempts:

3 left

💡 Hint

Common Mistakes

Including KeyError which is unrelated here

Not using a tuple for multiple exceptions

This test expects one of three exceptions: AttributeError if the method does not exist, TypeError if the call is invalid, or ValueError for invalid values.
