Testing a before_filter with a Rails.env condition

Testing RSpec
1

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.

def check_for_something
if Rails.env == ‘production’
…
end
end

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

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

HTH,

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 :wink:
