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.
