Pytest-django: py.test: error: unrecognized arguments: --reuse-db

[rodrigorodriguescosta]

When I type : py.test show the error

py.test: error: unrecognized arguments: --reuse-db

my pytest.ini

  [pytest]
  addopts = --reuse-db
  DJANGO_SETTINGS_MODULE=untitled1.settings

My test_unidade.py

import pytest

__author__ = 'Rodrigo'
pytestmark = pytest.mark.django_db

@pytest.mark.django_db
def test_cadastra_unidade():
    unidade = TipoUnidade()
    unidade.nome = 'AA'
    unidade.save()

I followed this tutorial http://pytest-django.readthedocs.org/en/latest/database.html

I'd like pytest creates the database like django test

What's wrong?

Probably it can be related with your environment. Can you show how you run tests? and pip freeze also will be good.

When I remove the param addopts = --reuse-db from pytest.ini the tests runs normally, but the database is not created.

When I run py.test shows only the message

 usage: py.test [options] [file_or_dir] [file_or_dir] [...]
 py.test: error: unrecognized arguments: --reuse-db

I don't see pytest-django installed in your environment. So, probably, it is a reason. To list active plugins for py.test you can run:

When plugin is installed, you can use extra comandline options provided by that plugin, if not, you'll get error.

Thanks for the report! As @Stranger6667 points out, this looks like pytest-django is not properly installed.

Please reopen this issue if django shows up in --traceconfig and --reuse-db does still does not work, or if there is anything that you think we can improve in the getting started tutorial.
