Tests fail: missing Mongoid config file

[joliss]

Running bundle install && rake on HEAD (fb4ec) with Ruby 1.9.2 fails with the following error message:

Mongoid config not found. Create a config file at: config/mongoid.yml
to generate one run: rails generate mongoid:config

/var/lib/gems/1.9.1/gems/mongo-1.1.2/lib/mongo/connection.rb:495:in `connect': failed to connect to any given host:port (Mongo::ConnectionFailure)

Full output: https://gist.github.com/772968

I couldn't find any info on this in the README or at https://github.com/plataformatec/devise/wiki/Contributing , so I'm lost at this point. Is there anything I have to set up to run the tests, or is there a file missing from the repository (or some other problem with the test suite)?

You don't need a config (we configure it manually). But you need to have mongo running. If this does not work at all, feel free to create a config file at test/rails_app/config/mongoid.yml.

Thanks! I was thrown off by the message about the missing config file.

I'd like to add a note to the documentation that MongoDB 1.6 or newer is required to run the tests, but I'm not sure where to put it. Do you think the README is a good place? (I'm wondering because it serves as a home page, and most users won't want to run devise's test suite.)

(From #770.)

About the warning, I think that it should be raised by the mongoid gem, no? Devise does not do anything in special...

(I'm assuming you're referring to the config file warning here, right?) Yeah -- I guess it'd be nice to suppress it, but so long as the tests run fine, I don't think it's a big deal. The warning followed by an immediate failure just made me assume that it was the cause of the failure.

And for posterity, it specifically happens in mongoid's lib/mongoid/railtie.rb:

  # After initialization we will attempt to connect to the database, if
  # we get an exception and can't find a mongoid.yml we will alert the user
  # to generate one.
  initializer "verify that mongoid is configured" do
    config.after_initialize do
      begin
        ::Mongoid.master
      rescue ::Mongoid::Errors::InvalidDatabase => e
        unless Rails.root.join("config", "mongoid.yml").file?
          puts "\nMongoid config not found. Create a config file at: config/mongoid.yml"
          puts "to generate one run: rails generate mongoid:config\n\n"
        end
      end
    end
  end
