I’m trying to set up testing on my ActiveResource project. The  
HttpMock appears to be what I want, but whenever I use the code in the  
“documentation”, I get the error

NameError: uninitialized constant ActiveResource::HttpMock

Is there something I need to do to enable HttpMock testing?

Thanks,  
Tom

I’ve never used HttpMock for testing, but I’d recommend checking out  
Fakeweb  
([http://fakeweb.rubyforge.org/](http://fakeweb.rubyforge.org/)) for testing against external resource. I  
use  
it for ActiveResource calls and for hitting other external APIs.

Hope that helps.

require ‘active\_resource/http\_mock’ first 😉

Oh wow. That was easy. Thanks Jeremy!

p.s. Did you find that documented somewhere?
