Define a "good" API

[matclab]

The way the test are written (with w fixtures, and call and form_post imported from the helper module) is mainly inherited from day to day patching in order to make test work.

The API shall certainly be think about a bit more to adjust to the need express by people.

The actual state of the API shall be documented first though.

[matclab]

For now, the fixtures which have the same name that call arguments, shall be set explicitly:

@pytest.fixture
def controller():
   return 'myctrl'

def test_call(w, controller):
   assert call(w, 'funcname', controller=controller)

It would be nice to be able in call to use the fixtures for the parameters…

Not sure if doable without too much of magic.
