Test classes in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a test class in pytest.

PyTest

class TestExample:
    def [1](self):
        assert 1 + 1 == 2

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

Acheck_add

Ctest_addition

Dverify_addition

💡 Hint

Common Mistakes

Not starting the method name with 'test_' so pytest skips the test.

Using a method name that does not follow pytest naming conventions.

The method name must start with test_ for pytest to recognize it as a test.

2fill in blank

medium

Complete the code to use a setup method in a pytest test class.

PyTest

class TestSetup:
    def [1](self):
        self.value = 10

    def test_value(self):
        assert self.value == 10

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

Asetup_method

BsetUp

Csetup_class

Dsetup

Attempts:

3 left

💡 Hint

Common Mistakes

Using setup or setUp which are not recognized by pytest.

Using setup_class which runs once per class, not before each test.

In pytest, setup_method is used to run setup code before each test method.

3fill in blank

hard

Fix the error in the test class to correctly use a class-level setup in pytest.

PyTest

class TestClassSetup:
    @classmethod
    def [1](cls):
        cls.data = [1, 2, 3]

    def test_data_length(self):
        assert len(self.data) == 3

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

AsetupMethod

Bsetup_class

Csetup_class_method

Dsetup

💡 Hint

Common Mistakes

Using incorrect method names like setupMethod or setup.

Not using the @classmethod decorator.

The correct class-level setup method name in pytest is setup_class decorated with @classmethod.

4fill in blank

hard

Fill both blanks to correctly skip a test method conditionally in a pytest test class.

PyTest

import pytest

class TestSkip:
    @pytest.mark.[1](reason="Not ready")
    def [2](self):
        assert False

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

Askip

Bskipif

Ctest_skip

Dtest_skip_method

Attempts:

3 left

💡 Hint

Common Mistakes

Using skipif without a condition.

Naming the test method without the test_ prefix.

The decorator @pytest.mark.skip skips the test unconditionally. The test method must start with test_.

5fill in blank

hard

Fill all three blanks to correctly parametrize a test method inside a pytest test class.

PyTest

import pytest

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

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

Aparametrize

Btest_increment

Cinput

Dvalue

Attempts:

💡 Hint

Common Mistakes

Using wrong decorator names like parameterize.

Mismatch between parameter names in decorator and method signature.

Use @pytest.mark.parametrize to run a test with multiple inputs. The test method must start with test_. The parameter name must match the first argument of parametrize.
