Nice little DSL trick for extending ExampleGroups in RSpec

describe ‘migration_generator’ do
include RSpec::Rails::Orm::ActiveRecord
include RSpec::Rails::Migration

end

Didn’t quite feel right. So I made it prettier DSL like using the
solution below :wink:

class Class
def use_orm orm
class_eval do
include “RSpec::Rails::Orm::#{orm.to_s.camelize}”.constantize
end
end

def specify_for type
raise ArgumentError, “Can not specify for #{type}” if !
[:migration, :model].include?(type)
class_eval do
include “RSpec::Rails::#{type.to_s.camelize}”.constantize
end
end
end

describe ‘migration_generator’ do
use_orm :active_record
specify_for :migration


end

Could it be done in a better way without polluting Class or some other
low lv Ruby class?
I want the functions from the included module to be avalable within
all my: before, after, it, describe etc. blocks.
