rspec users - Aug 2011 - Testing a before_filter with a Rails.env condition

Hi

We have the occasional ApplicationController before_filter that is
conditioned by the Rails.env and we like the following style:

  before_filter :check_for_something if Rails.env ==
''production''

And wish to spec this in an ApplicationController spec using an anonymous
controller (e.g.
http://relishapp.com/rspec/rspec-rails/docs/controller-specs/anonymous-controller
)

*Q. Just wondering how we can
Rails.stub(:env).and_return(''production'') to
trigger the before_filter?*

As it stands we have moved the conditional down into the method and stub in
the before(:each)

e.g.

before_filter :check_for_something

def check_for_something
  if Rails.env == ''production''
      ...
  end
end

before(:each) do
  Rails.stub(:env).and_return(''production'')
 end

Cheers
Shane

This approach won''t work because this line is eval''d once and
only once when the file is loaded.

This approach works because Rails.env inside the check_for_something method is
eval''d each time the method is called.

Yeah sorry I realised that was what was happening.

But thought I''d ask the question in case there might have been
something I
was missing (in the docs) or a smart hack ;-)
