Urls concerns
|
|
-------------
|
|
|
|
# Basic usage
|
|
|
|
Attributes:
|
|
url_name (str): Name of view under test, as given to 'reverse'
|
|
function.
|
|
url_args (list, optional): Will be given to 'reverse' call.
|
|
url_kwargs (dict, optional): Same.
|
|
url_expcted (str): What 'reverse' should return given previous
|
|
attributes.
|
|
|
|
View url can then be accessed at the 'url' attribute.
|
|
|
|
# Advanced usage
|
|
|
|
If multiple combinations of url name, args, kwargs can be used for a view,
|
|
it is possible to define 'urls_conf' attribute. It must be a list whose
|
|
each item is a dict defining arguments for 'reverse' call ('name', 'args',
|
|
'kwargs' keys) and its expected result ('expected' key).
|
|
|
|
The reversed urls can be accessed at the 't_urls' attribute.
|
|
|
|
|
|
Users concerns
|
|
--------------
|
|
|
|
During setup, the following users are created:
|
|
- 'user': a basic user without any permission,
|
|
- 'root': a superuser, account trigramme: 200.
|
|
Their password is their username.
|
|
|
|
One can create additionnal users with 'get_users_extra' method, or prevent
|
|
these users to be created with 'get_users_base' method. See these two
|
|
methods for further informations.
|
|
|
|
By using 'register_user' method, these users can then be accessed at
|
|
'users' attribute by their label.
|
|
|
|
A user label can be given to 'auth_user' attribute. The related user is
|
|
then authenticated on self.client during test setup. Its value defaults to
|
|
'None', meaning no user is authenticated.
|
|
|
|
|
|
Automated tests
|
|
---------------
|
|
|
|
# Url reverse
|
|
|
|
Based on url-related attributes/properties, the test 'test_urls' checks
|
|
that expected url is returned by 'reverse' (once with basic url usage and
|
|
each for advanced usage).
|
|
|
|
# Forbidden responses
|
|
|
|
The 'test_forbidden' test verifies that each user, from labels of
|
|
'auth_forbidden' attribute, can't access the url(s), i.e. response should
|
|
be a 403, or a redirect to login view.
|
|
|
|
Tested HTTP requests are given by 'http_methods' attribute. Additional data
|
|
can be given by defining an attribute '<method(lowercase)>_data'.
