An extension of pytest test runner which provides a set of useful tools to simplify testing and development of the Flask extensions and applications.

How to start?

Considering the minimal flask application factory bellow in myapp.py as an example:

from flask import Flask

def create_app(config_filename):
   # create a minimal app
   app = Flask(__name__)
   app.config.from_pyfile(config_filename)

   # simple hello world view
   @app.route('/hello')
   def hello():
      return 'Hello, World!'

   return app

You first need to define your application fixture in conftest.py:

from myapp import create_app

@pytest.fixture
def app():
    app = create_app()
    return app

Finally, install the extension with dependencies and run your test suite:

$ pip install pytest-flask
$ pytest
