  names.each do |name|

# @return [String] the current example group description

  description = metadata[:description]
  RSpec.configuration.format_docstrings_block.call(description)
end


# Returns the class or module passed to the `describe` method (or alias).
# Returns nil if the subject is not a class or module.
# @example
#     RSpec.describe Thing do
#       it "does something" do
#         described_class == Thing
#       end
#     end

Hah, nawet działa

[code=ruby]require ‘rspec’

class Boromir
def walk_into_mordor!
raise “Nope”
end
end

RSpec::Core::ExampleGroup.singleton_class.define_example_method :one

describe Boromir do
one ‘does not simply walk into mordor’ do
expect {
Boromir.new.walk_into_mordor!
}.to raise_error(‘Nope’)
end
end[/code]
