Complete the code to import pytest for writing tests.

💡 Hint

Common Mistakes

Importing unrelated modules like requests or json.

Using unittest instead of pytest for this example.

We use pytest to write and run tests in Python.

medium

Complete the code to define a simple integration test function.

PyTest

def test_components_work_together():
    result = component_a() [1] component_b()
    assert result == 'success'

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

💡 Hint

Common Mistakes

Using logical operators like 'and' which don't combine values.

Using multiplication or subtraction which don't apply here.

We combine outputs from component_a() and component_b() using + to simulate integration.

3fill in blank

hard

Fix the error in the assertion to correctly check the integration result.

PyTest

def test_integration():
    output = integrate_components()
    assert output [1] 'expected output'

💡 Hint

Common Mistakes

Using inequality operator instead of equality.

Using comparison operators like > or < which don't apply.

The assertion should check if output equals the expected string using ==.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps component names to their test results if the result is successful.

PyTest

results = {name: result for name, result in components.items() if result [1] 'success' and name [2] 'component_x'}

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

A==

B!=

💡 Hint

Common Mistakes

Mixing up equality and inequality operators.

Using the same operator for both blanks incorrectly.

The comprehension keeps items where result == 'success' and name != 'component_x'.

5fill in blank

hard

Fill all three blanks to create a test that asserts all components return 'ok' status.

PyTest

def test_all_components_ok():
    statuses = {name: status for name, status in check_statuses().items() if status [1] 'ok'}
    assert all(status [2] 'ok' for status in statuses.values()) [3] True

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

A==

D!=

💡 Hint

Common Mistakes

Using '!=' instead of '==' in filters or checks.

Using '==' instead of 'is' for boolean comparison.

The comprehension filters statuses equal to 'ok', the assertion checks all statuses equal 'ok', and is True confirms the boolean result.
