Source code for joop.cli.test_flask

"""Flask testing module for joop.

This module provides functionality to start a Flask webserver for testing and development purposes.

Important: The test joop env is set as the jinja env for the Flask server. This is specific and desirable
    though your project may implement the environment otherwise.

Functions:
    start_test_flask():
        Starts the Flask webserver in debug mode using the `app` instance from `joop.flask`.

Dependencies:
    - Flask: Ensure Flask is installed. If not, install it using `pip install joop[flask]`.

Usage:
    - Import the `start_test_flask` function and call it to start the Flask webserver.
