pytest-flask 1.3.0

A set of py.test fixtures to test Flask applications.

pytest-flask

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

To view a more detailed list of extension features and examples go to the PyPI overview page or package documentation.

How to start?

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

from flask import Flask

def create_app():
   # create a minimal app
   app = Flask(__name__)

   # 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

Changelog

1.3.0 (2023-10-23)

• Fix compatibility with Flask 3.0 – the consequence is that the deprecated and incompatible request_ctx has been removed.

1.2.1

• Fix bug in :meth:pytest_flask.fixtures.live_server where SESSION_COOKIE_DOMAIN was set to false due to original_server_name defaulting to “localhost”. The new default is “localhost.localdomain”.

• Drop support for python 3.6 and 3.5

1.2.0 (2021-02-26)

• Remove deprecated :meth:live_server.url

• fixture request_ctx is now deprecated and will be removed in the future

• JSONReponse.json removed in favour of Werkzeug.wrappers.Response.json

1.1.0 (2020-11-08)

• Speedup live server start time. Use socket instead of server pulling (#58) to check server availability and add new --live-server-wait option to set the live server wait timeout. Thanks to @jadkik.

1.0.0 (2020-03-03)

Important

• live_server is now session-scoped by default. This can be changed by using the live-server_scope option in your pytest.ini (#113). Thanks @havok2063 for the initial patch and @TWood67 for finishing it up.

• pytest 5.2 or later is now required.

• Python 2.7 and 3.4 are no longer supported.

0.15.1 (2020-02-03)

• Fix ImportError with Werkzeug 1.0.0rc1 (#105).

0.15.0 (2019-05-13)

• Properly register the options marker (#97).

0.14.0 (2018-10-15)

• New --live-server-host command-line option to set the host name used by the live_server fixture.

  Thanks @o1da for the PR (#90).

0.13.0 (2018-09-29)

• JSONReponse now supports comparison directly with status codes:

  assert client.get('invalid-route', headers=[('Accept', 'application/json')]) == 404

  Thanks @dusktreader for the PR (#86).

0.12.0 (2018-09-06)

• pytest-flask now requires pytest>=3.6 (#84).

• Add new --live-server-port option to select the port the live server will use (#82). Thanks @RazerM for the PR.

• Now live_server will try to stop the server cleanly by emitting a SIGINT signal and waiting 5 seconds for the server to shutdown. If the server is still running after 5 seconds, it will be forcefully terminated. This behavior can be changed by passing --no-live-server-clean-stop in the command-line (#49). Thanks @jadkik for the PR.

• Internal fixes silence pytest warnings, more visible now with pytest-3.8.0 (#84).

0.11.0 (compared to 0.10.0)

• Implement deployment using Travis, following in line with many other pytest plugins.
