Combining multiple parametrize decorators in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to parametrize the test with two values for x.

PyTest

@pytest.mark.parametrize('x', [1, 2])
def test_example([1]):
    assert x > 0

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

💡 Hint

Common Mistakes

Using a different parameter name in the function than in the decorator.

The parameter name in the test function must match the name used in the parametrize decorator.

medium

Complete the code to add a second parametrize decorator for y.

PyTest

@pytest.mark.parametrize('x', [1, 2])
@pytest.mark.parametrize([1], [3, 4])
def test_example(x, y):
    assert x + y > 0

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

💡 Hint

Common Mistakes

Using a parameter name that does not match the function argument.

The second parametrize decorator must use the parameter name 'y' to match the function argument.

3fill in blank

hard

Fix the error in the combined parametrize decorators to test all combinations of x and y.

PyTest

@pytest.mark.parametrize('x', [1, 2])
@pytest.mark.parametrize('y', [1])
def test_example(x, y):
    assert x != y

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

B[3, 4]

💡 Hint

Common Mistakes

Using parentheses or braces instead of square brackets for the parameter list.

The parametrize decorator expects a list of values for the parameter.

4fill in blank

hard

Fill both blanks to parametrize test with x and y and check their sum.

PyTest

@pytest.mark.parametrize([1], [1, 2])
@pytest.mark.parametrize([2], [3, 4])
def test_sum(x, y):
    assert x + y > 0

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

A'x'

B'z'

C'y'

D'value'

💡 Hint

Common Mistakes

Swapping parameter names or using incorrect names.

The first decorator should parametrize 'x' and the second 'y' to match the function parameters.

5fill in blank

hard

Fill all three blanks to parametrize x, y, and z and assert their product.

PyTest

@pytest.mark.parametrize([1], [1, 2])
@pytest.mark.parametrize([2], [3, 4])
@pytest.mark.parametrize([3], [5, 6])
def test_product(x, y, z):
    assert x * y * z > 0

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

A'x'

B'y'

C'z'

D'value'

💡 Hint

Common Mistakes

Using incorrect parameter names or missing one.

Each parametrize decorator must match the corresponding function parameter name.
