from requests_mock_flask import add_flask_app_to_mock

app = flask.Flask(__name__)

@app.route('/')
def _() -> str:
    return 'Hello, World!'

@responses.activate

        flask_app=app,
        base_url='http://www.example.com',
    )

    response = requests.get('http://www.example.com')

    assert response.status_code == 200
    assert response.text == 'Hello, World!'

        )

        response = requests.get('http://www.example.com')

    session = requests.Session()
    adapter = requests_mock.Adapter()
    session.mount('mock', adapter)

    add_flask_app_to_mock(
        mock_obj=adapter,
        flask_app=app,
        base_url='mock://www.example.com',
    )

    response = session.get('mock://www.example.com')

    assert response.status_code == 200
    assert response.text == 'Hello, World!'

Use cases

  • Use the requests API for testing applications.
  • Create a test suite which can test a Flask application as well as a live web application, to make a verified fake.
  • Test a service which calls a Flask application that you have the source code for.
