[RSpec] Setting a gem dep on rspec-rails

#1

For a while now, I’ve had the following in config/environment.rb :

config.gem ‘haml’
config.gem ‘rspec’, :lib => ‘spec’
config.gem ‘rspec-rails’, :lib => ‘spec/rails’

I just tried running the Rails console in production mode, and this
warning occured:

irb: warn: can’t alias context from irb_context.

After some googling, I learned that the gem deps on rspec and rspec-
rails are causing that warning. When I remove those two gem deps from
environment.rb , the warning disappears.

With that said, I’m wondering what the accepted way to setup gem
dependencies on rspec and rspec-rails is. Should one not bother?
Should the “config.gem” lines go in config/environments/test.rb ?

Thanks,
Nick

I should’ve tried the second solution I proposed before sending that
email. If you put the gem dependencies in config/environments/test.rb
and then enter the Rails console in test mode (script/console test),
the warning occurs.

Rails config.gem has never seemed to work 100% with libraries that
shouldn’t be loaded in all environments. With that said, I point you
to the wiki:

http://wiki.github.com/dchelimsky/rspec/rails-with-rspec-gems

If you try to use the rake tasks to find gem dependencies for your
app, it will not list them by default unless you set RAILS_ENV=test.

ie: RAILS_ENV=test rake gems

IMO, running “rake gems” should tell you the configured gems for
everything, and it should say what environments a particular gem is
required. It kind of defeats the purpose if I have to be so specific
when asking the “rake gems” task what gems the application relies on.

I’ve haven’t successfully gotten all of the rake tasks for gems to
work 100% in the test environment. For the most part the “gems” and
“gems:unpack” do function.

You can successfully bypass cofnig.gem and the associated rake tasks
by using “gem unpack”.

ie: cd vendor/gems ; gem unpack rspec ; gem unpack rspec-rails

Personally, I put rspec and rspec-rails in vendor/plugins, even if
it’s just using “gem unpack” to put them there. It makes easier to
upgrade to recent changes in rspec/rspec-rails in order to try out bug
fixes, or take advantage of new features.

Basically you’ve got options. I’d recommend gem unpacking into
vendor/gems or vendor/plugins. I don’t see an advantage at this point
of using config.gem since it doesn’t work 100% of the time, and it
doesn’t work necessarily as it should (of course IMO),

I don’t bother to use config.gem with rspec, but if you do then yes it
should go in test.rb

I don’t either, but I’d like to get it working for ppl who want to do
it.

If anybody w/ config.gem fu wants to help, that’d be awesome.

So yeah, executive summary: What Pat said.

I’ve decided to just freeze the rspec and rspec-rails gems into vendor/
gems/ . It makes life easy when moving the app between hosts, and
means that I don’t have to worry about config.gem shenanigans.

Thanks for all of your suggestions, guys. Much appreciated!

I think this kinda works for us, but I had a couple of issues. One is
the problem with rake files, which will depend on RSpec being visible
to rake when it loads (which will ignore your vendor/gems folder). I
fixed that by putting the rake file in a huge begin / rescue / end
block so when the require ‘spec’ fails it doesn’t load the rest of the
rake tasks. Ugly but functional.

The other issue was to do with a line in spec/rails which clobbers the
value of RAILS_ENV to be ‘test’ whatever it was previously set to. We
use an unconventional ‘features’ environment for running features
(means I can run cukes at the same time as specs) but this was going
hay-wire. I think David has put a patch for this into rspec-rails’
head but I don’t know if it’s made it’s way into a gem yet.

So yeah, executive summary: What Pat said.
