If you didn't have that line yet (recommended, because test-first makes this
stuff very easy), then what missing behavior would you see in the resulting
page? Would it behave as if the user were logged out?
Get that behavior going, then specify it didn't happen, and that the correct
If you merely test that logged_in_member got called, and if it caught a bug, the
spec you envision would simply continue to report it was called. Behavior Driven
Development is about specifying behaviors at a slightly higher level than their
raw source lines!
Also, why isn't logged_in_member called from a "before" action? And
I would also build a scratch Rails site and throw the "salted authentication"
plugin at it. That generates a very nice set of unit tests which show how things
like this are done, IIRC!
