python3 -m pip install -r requirements.txt

Development

To start the app in development mode, execute

./run_app_dev.sh

The application will then be available at localhost:5000. You can test the functionality manually using curl, e.g. via

curl localhost:5000/api/v1/path_for_blueprint_x/test

or through the automated tests, by running

pytest

The commands should output

{
  "msg": "I'm the test endpoint from blueprint_x."
}

and

test/test_endpoints.py ....
