xdist disable suffix

[lestatcheb]

need if we want to use only one database for xdist

[lestatcheb]

any news for this pull request?

[pelme]

Can you explain why this is needed? It seems to be that this will use the same database name for all xdist-processes - how would that be useful?

I am a bit skeptical about putting it in the Django settings, I think it would be better to have a pytest command line option or setting in pytest.ini for it.

Also: Before merging this there needs to be a test for it in https://github.com/pelme/pytest_django/blob/master/tests/test_db_setup.py.

It useful when you want use pytest-django with some external database (which use other people) and only with reuse-db option.
We use this for integration tests (instead of selenium) which go to network (instead of fixtures) and create some new data always in one external database.

I rewrote code to command line option and added test for 'gw' prefix.

Review please

Any news, guys?

@lestatcheb Thanks for the effort you have put into this.

However, I would like to finalize my work in the fixturefix branch. It will make configuration of the test database name trivial in any project, by just providing a custom fixture that does the database mangling. In this case that fixture would not really do anything, so it should be very straightforward. This issue will certainly be an example in the documentation.

See my comment in #128 for some more details about my plans. There will be more updates on this development after EuroPython.

To understand what you are trying to achieve a bit more: Are you having a single database and only do read only queries against it for all tests? What you are doing is probably not working 100 % reliable if you have any write queries unless there is something that I miss.

Again, thanks for working on this!

Ok, thanks you for great project :)
I'll wait for fixturefix branch.

No, we have a single database with read and write queries.
Ok, I tell more details.
We have dev environment, which contains:

1. One postgresql database
2. Many dev servers for testing new branches.
   Each dev server use one database which I mentioned above.
   Each server have gunicorns, nginx, etc.

We have some api which used by other services in dev.
Also we need to test some external api which we use by own.

So, if we need to test all these api we must use one database with reuse-db.
External api tests are very long (each test about 1-3 minutes), so we need to parallel them.
Here we need to run all our tests with xdist plugin, but we want use the same postgresql database for all tests.
These tests are like integration tests for testing all services we use.
We don't want to use selenium tests with browser, it is enough just to test api.

Should this be closed in favor of #336?

[pelme]

this is fixed in pytest 3.0, see the documentation and raise new issues/PRs if needed!
