Optionally testing caching in Rails 3 functional tests -

generally, want functional tests not perform action caching. rails seems on side, defaulting config.action_controller.perform_caching = false in environment/test.rb. leads normal functional tests not testing caching.

so how test caching in rails 3.

the solutions proposed in thread seem rather hacky or taylored towards rails 2: how enable page caching in functional test in rails?

i want like:

test "caching of index method"   with_caching     :index     assert_template 'index'     :index     assert_template ''   end end 

maybe there better way of testing cache hit?

you're liable end tests stomping on each other. should wrap ensure , reset old values appropriately. example:

module actioncontroller::testing::caching   def with_caching(on = true)     caching = actioncontroller::base.perform_caching     actioncontroller::base.perform_caching = on     yield   ensure     actioncontroller::base.perform_caching = caching   end    def without_caching(&block)     with_caching(false, &block)   end end 

i've put module can include in test class or parent class.
