Naming conventions
We found so far a few patterns emerging in our py.test fixtures. The naming conventions for those are documented on this page.
Utilities - _util
Used for fixtures which are used to ensure that the pre-conditions of the test are met. Usually it does not matter so much for the test how they achieve this. Most utilities will clean up automatically after themselves.
Use the suffix _util.
Page objects - {route_name}_page
Used as abstractions of pages.
Use the suffix _page and if possible use the route name as the prefix.
