This is used to mark a test function as requiring the database. It will ensure the database is setup correctly for the test. Each test will run in its own transaction which will be rolled back at the end of the test. This behavior is the same as Django’s standard django.test.TestCase class.
In order for a test to have access to the database it must either be marked using the django_db mark or request one of the db or transcational_db fixtures. Otherwise the test will fail when trying to access the database.
type transaction: bool param transaction: The transaction argument will allow the test to use real transactions. With transaction=False (the default when not specified), transaction operations are noops during the test. This is the same behavior that django.test.TestCase uses. When transaction=True, the behavior will be the same as django.test.TransactionTestCase
If you want access to the Django database inside a fixture this marker will not help even if the function requesting your fixture has this marker applied. To access the database in a fixture, the fixture itself will have to request the db or transactional_db fixture. See below for a description of them.
Specify a different settings.ROOT_URLCONF module for the marked tests.
|Parameters:||urls (string) – The urlconf module to use for the test, e.g. myapp.test_urls. This is similar to Django’s TestCase.urls attribute.|
@pytest.mark.urls('myapp.test_urls') def test_something(client): assert 'Success!' in client.get('/some_url_defined_in_test_urls/')
pytest-django provides some pytest fixtures to provide dependencies for tests. More information on fixtures is available in the py.test documentation.
An instance of a django.test.client.RequestFactory
from myapp.views import my_view def test_details(rf): request = rf.get('/customer/details') response = my_view(request) assert response.status_code == 200
An instance of a django.test.Client
def test_with_client(client): response = client.get('/') assert response.content == 'Foobar'
An instance of a django.test.Client, that is logged in as an admin user.
def test_an_admin_view(admin_client): response = admin_client.get('/admin/') assert response.status_code == 200
As an extra bonus this will automatically mark the database using the django_db mark.
This fixture will ensure the Django database is set up. This only required for fixtures which want to use the database themselves. A test function should normally use the django_db() mark to signal it needs the database.
This fixture can be used to request access to the database including transaction support. This is only required for fixtures which need database access themselves. A test function would normally use the django_db() mark to signal it needs the database.
This fixture runs a live Django server in a background thread. The server’s URL can be retreived using the live_server.url attribute or by requesting it’s string value: unicode(live_server). You can also directly concatenate a string to form a URL: live_server + '/foo.
