Comment (by Rob Atkinson): Happy to suggest some documentation clarifications once I have got my test cases working.. I have been using setUp() for the data, but there is some initial data i want autoloaded in all environments, and as this is part of the app i want to do unit tests on the loading process too. i got a bit lost in the deprecation discussion around fixtures - is this auto loading something we want to do in migrations? Then i want to add some additional data, currently using setUp() - but setUpTestCase() should be fine - but here the question is the inheritance one - if i am testing an app that extends this app - the perhaps the pattern is to import and extend the test case and inherit these methods too? If the extended add needs to add data - does it override setUpTestCase() and then call super.setUpTestCase()? Finally (and this is my ultimate use case) - i have an app that allows a user to load a file and process it using metadata they provide. This app is then extended for specialised resource types - so i want a test case for a FileField. IMHO the testing guidelines should cover (at least with links to more information) the following common patterns - separation of unit and integration tests (is testing parsing of an uploaded file in an app a unit test? - i can test the parser separately - but i want to unit test the selection and setup of the parser with the uploaded file and other user supplied metadata ) - testing FileField CRUD operations (as these seem to require user code to handle cleanups then testing is vital - https://docs.djangoproject.com/en/2.0/topics/files/ does not provide information on how deletions are managed or testing processes - but if its handled automatically and we dont need to test this ourselves then lets add a note to explain that) - testing views that use external services. (there are various references to mocking and third party tools, but this seems to be a key function and the docs are silent) - for example, we wouldnt have a government application locally that wouldnt use the mandated official external street address validation service -- Ticket URL: <https://code.djangoproject.com/ticket/28983#comment:2> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
