在 Ruby 中使用 jasmine

gem 'jasmine'

Jasmine.configure do |config|
  # You can add rack handlers for specific urls
  config.add_rack_path '/something' do
    [200]
  end
  # And mount other rack applications
  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.
  config.runner = lambda do |formatter, server_url|
    My::Custom::Runner.new(formatter, server_url, 100)
  end
end

class My::Custom::Formatter
  # `format` is called by the runner every time it gets a batch of results from the page.
  # The parameter will be an array of `Jasmine::Result` objects
  def format(results)
    results.each do |result|
      puts result.status
    end
  end

  # `done` will be called by the runner after all results have come in.
  def done
    puts 'Done running tests'
  end
end

class My::Custom::Runner
  def initialize(formatter, jasmine_server_url, result_batch_size)
    # The formatter passed in is responsible for making sure all configured
    # formatters receive the same messages.
    @formatter = formatter
    # The `jasmine_server_url` is the full http://<host>:<port> url where
    # the jasmine server was started
    @jasmine_server_url = jasmine_server_url
    @result_batch_size = result_batch_size
  end

  # `run` is responsible coordinating the test run.
  def run
    # Here we're using Phantom to load the page and run the specs
    command = "#{Phantomjs.path} 'phantom_run.js' #{@jasmine_server_url} #{@result_batch_size}"
    IO.popen(command) do |output|
      # The `phantom_jasmine_run.js` script writes out batches of results as JSON
      output.each do |line|
        raw_results = JSON.parse(line, :max_nesting => false)
        # Formatters expect to get `Jasmine::Result` objects.
        # It is the runner's job to convert the result objects from the page,
        # and pass them to the `format` method of their formatter.
        results = raw_results.map { |r| Result.new(r) }
        @formatter.format(results)
      end
    end
    # When the tests have finished, call `done` on the formatter to run any
    # necessary completion logic.
    @formatter.done
  end

  # If the runner needs some javascript to be loaded into the page as part of the load,
  # it returns the full path in `boot_js`
  def boot_js
    File.expand_path('runner_boot.js', __FILE__)
