Quick answer:
One well-trodden path is to use the adapter pattern to isolate the behaviour
that actually interacts with the external file / network system behind an
interface. I'd recommend Steve Freeman and Nat Pryce's book "Growing Object
Oriented Software, Guided by Tests" (GOOS) where they talk about this in
detail, as well as many other very useful testing techniques. The examples are
in java, but the design principles apply equally to Ruby code.

[rspec-users] Routing assertions
Hi
Thanks for help me out
I have two routes :
match 'admin/categories' => 'admin#categories', :as =>
'admin_category'
match 'admin/categories/:sub_category' => 'admin#categories'
In rspec
--
For first route
assert_routing({:path => "admin/categories"}, {:controller =>
'admin', :action => 'categories'})
For second route
assert_recognizes({:controller=>'admin', :action =>
'categories', :sub_category=>'2'}, 'admin/categories/2')
---
For second route if i am using assert_routing method I am getting
below error
Failure/Error: assert_routing({:path => "admin/categories/2"},
{:controller => 'admin', :action => 'categories', :sub_category =>
'2'})
Test::Unit::AssertionFailedError:
found extras <{:sub_category=>"2"}>, not <{}>
Why assert_routing method is failing for second route? And also let
me know I which scenarios should I use assert_routing,
assert_generates and assert_recognizes?

I've been using the VCR gem lately and it is great. Maybe this would be useful if you're fetching from git using http?? ___ rspec-users mailing list rspec-users@rubyforge.org http://rubyforge.org/mailman/listinfo/rspec-users
