Implement more fixtures

[ramnes]

A few tests (e.g. in test_helpers.py) implement the creation / deletion of the resources they need by themselves. This approach has a problem: if the test fails, the resources are left behind. Tests should have no side effect, shouldn't depend on other tests side effects, and should be idempotent.

I'd like to work on this. I've identified the problematic tests and have a solution , Can I take this on?

Of course! PR welcome.
