💡 Hint

Common Mistakes

Leaving __init__.py empty

Adding unnecessary code causing errors

An empty __init__.py file with 'pass' makes the folder a package without errors.

4fill in blank

hard

Fill both blanks to create a test package with a test module and a test function.

PyTest

tests/
  __init__.py
  test_math.py

# Inside test_math.py:
def [1]():
    assert 3 * 3 == [2]

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

Common Mistakes

Wrong function name not starting with 'test'

Wrong expected value in assertion

The function name must start with 'test' and the assertion must check the correct product 9.

5fill in blank

hard

Fill all three blanks to create a test package with a test module, test function, and a failing assertion.

PyTest

tests/
  __init__.py
  test_strings.py

# Inside test_strings.py:
def [1]():
    result = 'hello'.upper()
    assert result == '[2]'
    assert result != '[3]'

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

Wrong function name

Wrong expected string in assertion

Confusing uppercase and lowercase

The test function checks that 'hello'.upper() equals 'HELLO' and is not 'hello'.
