When you write a module, you write unit tests (or you should - I don't because I am a bad person, but I want to change - honest).
Should modules generated with Features be unit tested where applicable/possible, or is a suite of Selenium tests enough?
For example, say I have a Feature that has a node type and a couple of user roles and/or permissions for said content type. Is it good practice (or even necessary) for SimpleTests to be written to test creation of my content type?
For clarity, I am aware of Unit test for custom content type, but I am after an answer regarding all unit testable functionality, not just content types.
