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:

.. code-block:: python

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:

.. code-block:: python

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.

.. _@havok2063: https://github.com/havok2063 .. _@TWood67: https://github.com/TWood67 .. _#113: https://github.com/pytest-dev/pytest-flask/pull/113

0.15.1 (2020-02-03)

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

.. _#105: https://github.com/pytest-dev/pytest-flask/pull/105

0.15.0 (2019-05-13)

Properly register the options marker (#97_).

.. _#97: https://github.com/pytest-dev/pytest-flask/pull/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_).

.. _@o1da: https://github.com/o1da .. _#90: https://github.com/pytest-dev/pytest-flask/pull/90

0.13.0 (2018-09-29)

JSONReponse now supports comparison directly with status codes:

.. code-block:: python
```
assert client.get('invalid-route', headers=[('Accept', 'application/json')]) == 404
```
Thanks @dusktreader_ for the PR (#86_).

.. _@dusktreader: https://github.com/dusktreader .. _#86: https://github.com/pytest-dev/pytest-flask/pull/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_).
