Practice - 5 Tasks

Complete the code to import the requests library for testing external services.

💡 Hint

Common Mistakes

Importing pytest instead of requests

Importing unittest which is for unit tests, not HTTP calls

The requests library is used to make HTTP calls to external services in tests.

medium

Complete the code to mock the external HTTP GET request using pytest and requests.

PyTest

def test_api_call(mocker):
    mock_get = mocker.patch('requests.[1]')
    mock_get.return_value.status_code = 200
    response = requests.get('http://example.com')
    assert response.status_code == 200

💡 Hint

Common Mistakes

Patching the wrong HTTP method like post or put

Not patching the requests method at all

The get method is patched to mock the HTTP GET request.

3fill in blank

hard

Fix the error in the test by completing the assertion to check the mocked JSON response.

PyTest

def test_api_json_response(mocker):
    mock_get = mocker.patch('requests.get')
    mock_get.return_value.status_code = 200
    mock_get.return_value.json = lambda: {'key': 'value'}
    response = requests.get('http://example.com')
    assert response.json() [1] {'key': 'value'}

💡 Hint

Common Mistakes

Using 'is' which checks identity, not equality

Using '!=' which checks for inequality

The assertion should check equality with == to verify the JSON content.

4fill in blank

hard

Fill both blanks to create a pytest fixture that mocks requests.post and returns a 201 status code.

PyTest

@pytest.fixture
def mock_post(mocker):
    mock = mocker.patch('requests.[1]')
    mock.return_value.status_code = [2]
    return mock

💡 Hint

Common Mistakes

Patching the wrong HTTP method

Using incorrect status code like 200 instead of 201

The fixture patches requests.post and sets the status code to 201 (Created).

5fill in blank

hard

Fill all three blanks to write a test that uses the mock_post fixture and asserts the response status code is 201.

PyTest

def test_create_resource(mock_post):
    response = requests.[1]('http://example.com/resource')
    assert response.[2] == [3]

💡 Hint

Common Mistakes

Using 'get' instead of 'post' for creation

Checking wrong attribute like 'json' instead of 'status_code'

Expecting wrong status code like 200

The test calls requests.post, checks status_code, and expects 201.
