Gem which uses dummy rails app for tests

[Balasankar C <balasankarc@autistici.org>]

Hi,
Is there any documentation available on how to handle gems that use a
dummy rails app to test their functionality? I patched out the bundler
requirements but am getting this error

/usr/lib/ruby/vendor_ruby/rails/application/configuration.rb:105:in
`database_configuration': Cannot load
`Rails.application.database_configuration`: (RuntimeError)
Could not load database configuration. No such file -

It seems, the database.yml file is not getting detected.
The gem in question is rqrcode-rails3 which is a member of GitLab
runtime dependency chain.
