I don't think it's working incorrectly -- just a little unintuitively. 
In short,  R() only prepends the app root (i.e. '/test') to the 
generated URL when called from within a View -- not Controllers.

This can be worked around by using the "slash method"[1]:

     self / R(Foo, Bar) #=> '/test/foo/bar'

See the Camping docs for the R() helper method[2], and the "Using R in 
the View" section in particular, for a fuller explanation.
