Basically, we have an application layout that demands some content  
for, e.g. the sidebar… during functional testing, we want to assert  
that our views properly provide this content.

Example:

- application.rhtml has stuff like “yield :title”, “yield :sidebar”,  
etc.
- views contain “content\_for :title”, “content\_for :sidebar”, etc.

Question:

- When writing functional tests, is there a way to test that the views  
properly call “content\_for :sidebar”, i.e. that “yield :sidebar” in  
the layout does not result in an empty string?

I’m rather new to Rails, just started using functional tests a few  
days ago… despite much searching, I couldn’t find a solution to the  
issues above.

Any hints are greatly appreciated. – Thanks!
