使用 ruby 搭配 jasmine

gem 'jasmine'

Jasmine.configure do |config|
  # You can add rack handlers for specific urls
  config.add_rack_path '/something' do
    [200]

  config.add_rack_app MyRackApp
  # You can configure the port that the `rake jasmine` command starts a server on
  config.server_port = 12345
  # You can configure the port that the `rake jasmine:ci` command starts it's server on
  config.ci_port = 54321
  # You can add [custom formatters](#section-Custom_Formatters)
  config.formatters << My::Custom::Formatter
  # You can use a [custom runner](#section-Custom_Runners)
  # The `runner` option on config should be a lambda or Proc that receives a formatter
  # and server url and returns a constructed runner object. The lambda allows you to
  # configure other options that need to be configured at initialization time.
