Grouping related tests in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a test function using pytest.

PyTest

def test_[1]():
    assert 2 + 2 == 4

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

💡 Hint

Common Mistakes

Not starting the function name with 'test_' so pytest won't detect it.

Using vague names that don't describe the test purpose.

The test function name should start with test_ followed by a descriptive name. Here, test_addition clearly describes the test.

2fill in blank

medium

Complete the code to group related tests inside a class using pytest.

PyTest

class TestMathOperations:
    def [1](self):
        assert 3 * 3 == 9

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

Ccheck_multiply

Dmultiply_test

💡 Hint

Common Mistakes

Omitting 'test_' prefix in method names inside test classes.

Using method names that don't start with 'test_' so pytest skips them.

In pytest, test methods inside classes must start with test_ to be recognized as tests.

3fill in blank

hard

Fix the error in the test class so pytest recognizes the test method.

PyTest

class TestStrings:
    def [1](self):
        assert 'hello'.upper() == 'HELLO'

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

💡 Hint

Common Mistakes

Naming test methods without 'test_' prefix inside classes.

Using names that pytest does not recognize as tests.

Pytest requires test methods to start with test_ to detect and run them.

4fill in blank

hard

Fill both blanks to create a test class with two test methods for addition and subtraction.

PyTest

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

    def [2](self):
        assert 5 - 3 == 2

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

Atest_addition

Badd_test

Ctest_subtraction

Dsubtract_test

Attempts:

3 left

💡 Hint

Common Mistakes

Not using 'test_' prefix for one or both methods.

Using unclear or inconsistent method names.

Both test methods must start with test_ so pytest can find and run them.

5fill in blank

hard

Fill all three blanks to create a test class with grouped tests for multiplication, division, and modulus.

PyTest

class TestOperations:
    def [1](self):
        assert 4 * 2 == 8

    def [2](self):
        assert 10 / 2 == 5

    def [3](self):
        assert 10 % 3 == 1

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

Atest_multiply

Btest_divide

Ctest_modulus

Dmultiply_test

Attempts:

3 left

💡 Hint

Common Mistakes

Using inconsistent naming conventions for test methods.

Forgetting the 'test_' prefix on any method.

All test methods must start with test_ to be recognized by pytest. The names describe the operation tested.
