Simple test suite enabling Django app testing via $ python setup.py test
Project description
Django Setuptest
Simple module enabling Django app testing via $ python setup.py test.
Normally when you execute $ python setup.py test for Django related modules you’re almost certain to run into DJANGO_SETTINGS_MODULE environment variable issues, e.g.:
ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.
This module overcomes this by configuring the DJANGO_SETTINGS_MODULE environment variable before executing your test suite. As a bonus it also generates Coverage and PEP 8 reports as part of the test.
Installation
Provide a test_suite argument to the setup call specifying the setuptest.setuptest.SetupTestSuite test suite, e.g.:
setup( # ... test_suite='setuptest.setuptest.SetupTestSuite', )
Alternatively provide a cmdclass test argument to the setup call specifying the setuptest.test command, e.g.:
from setuptest import test #... setup( # ... cmdclass={'test': test}, )
This overrides Python’s builtin test command to enable the Django testrunner as well as allowing you to pass --failfast as a commandline argument, i.e.:
$ python setup.py test --failfast
For the cmdclass method to work django-setuptools should be installed and available in your Python path prior to running the test command, in which case django-setuptest is not required to be specified as part of the tests_required argument as detailed next.
Provide a tests_require argument to the setup call including django-setuptest (required only if not already installed) and other package dependencies needed to execute the tests, e.g.:
setup( # ... tests_require=( 'django-setuptest', ), )
Specify your test specific Django settings in a test_settings module in the same path as your app’s setup.py. These settings will be used when executing the tests, e.g. in test_settings.py:
DATABASE_ENGINE = 'sqlite3' INSTALLED_APPS = ( 'myapp', )
In order for the test suite to find your tests you must provide either a packages or py_modules argument to the setup call, e.g.:
from setuptools import setup, find_packages setup( # ... packages=find_packages(), ) # Or alternatively... setup( # ... py_modules=['myapp'], )
Usage
Once correctly configured you can execute tests from the command line:
$ python setup.py test
or, if you want the test suite to stop after the first test failure is detected:
$ python setup.py test --failfast
This should output your test results as well as Coverage and PEP 8 reports.
To mute the output of the Coverage and PEP 8 reports provide the --quiet option:
$ python setup.py test --quiet
To automatically restart the test runner when code changes are detected (similar to how runserver restarts) provide the --autoreload option:
$ python setup.py test --autoreload
To only run tests for a particular test case specify the test case as the --label option:
$ python setup.py test --label app.TestCase
Or for a particular test method specify the test case’s test method as the --label option:
$ python setup.py test --label app.TestCase.test_method
Sample Output
Example output of dummy test including Coverage and PEP 8 reports:
$ python setup.py test running test running egg_info writing django_dummy.egg-info/PKG-INFO writing top-level names to django_dummy.egg-info/top_level.txt writing dependency_links to django_dummy.egg-info/dependency_links.txt reading manifest file 'django_dummy.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' writing manifest file 'django_dummy.egg-info/SOURCES.txt' running build_ext Creating test database for alias 'default'...
