I'm trying to write a test for a method that uses a ferret search, but
can't validate that the results are a_a_f results because my class test
doesn't work.  Can anyone set me straight?  Here's some console
experimentation that shows the root of the problem.

>> users = User.find_with_ferret("max", :per_page => 2)
=> [#<User ...
...
]
>> users.size
=> 2
>> users.next_page #call a ferret-results-specific method
=> 2
>> users.kind_of?(ActsAsFerret::SearchResults)
=> false

What class should i be testing against, if it's not
ActsAsFerret::SearchResults?  If i do type on the results i just get
Array.

Hi,

SearchResults is a *really* thin wrapper around a standard Ruby Array
instance. If you really want to check it's a SearchResults instance
and not something else, check for Array and whether it behaves like it
should by looking at the 'special' methods the SearchResults class
adds, maybe like this:

assert_equal Array, results.class
%w(total_hits current_page per_page total_pages).each {|m| assert
results.respond_to?(m.to_sym) }

cheers,
Jens

ah ok.  i should have thought to just put that same method that i
referred to into a 'responds_to' call in my test, like you suggest :)

Thanks Jens
